Raising Snails
Heliciculture is the process of farming or raising snails. Snail farming on a large-scale
basis requires a considerable investment in time, equipment, and resources.
Prospective snail farmers should carefully consider these factors, especially if their
goal is to supply large quantities to commercial businesses. Anyone who wishes to
raise snails should expect to experiment until he finds what works best in his specific
situation. Expect a few problems.
Roasted snail shells have been found in archaeological excavations, an indication that
snails have been eaten since prehistoric times. In ancient Rome, snails were fattened
up in "cochlear" gardens before they were eaten. "A Virginia Farmer" (1)
described keeping snails in a cool, moist and shady environment, supplying artificial dew if
necessary, containing them on an "island" surrounded by water to prevent escape,
supplying vegetation as feed, and fattening them on corn meal.
Pliny described the snail garden of Fulvius Hirpinus 2,000 years ago as having separate
sections for different species of snails. Hirpinus allegedly fed his snails on meal and wine.
(2) [But note, stale beer placed in a shallow dish is a way of
killing them. Snails are attracted to the yeast in beer and will crawl into the dish and drown.]
The Romans selected the best snails for breeding. "Wall fish" were often eaten in Britain,
but were never as popular as on the continent. There, people often ate snails during Lent,
and in a few places, they consumed large quantities of snails at Mardi Gras or Carnival, as a
foretaste of Lent.
According to some sources, the French imported brown garden snails to California in
the 1850's, raising them as the delicacy escargot. Other sources claim that Italian
immigrants were the first to bring the snail to the U.S..
U.S. imports of snails were worth more than $4.5 million in 1995 and came from 24
countries. This includes preserved or prepared snails and snails that are live, fresh,
chilled, or frozen. Major exporters to the U.S. are France, Indonesia, Greece and
China. The U.S. exported live, fresh, chilled, or frozen snails worth $55,000 to 13
countries; most were shipped to Japan, the Netherlands, and the United Kingdom.

This publication provides a general overview of farming edible terrestrial snails. The
authors have used many sources believed to be reliable. Information supplied by some
farmers or researchers may conflict with information supplied by others. The
information applies to several different species of snails, and not all of it necessarily
applies to one particular species.

Edible land snails range in size from about one millimeter long to the giant African
snails, which occasionally grow up to 312mm (1 foot) in length. "Escargot" most
commonly refers to either Helix aspersa or to Helix pomatia, although other varieties
of snails are eaten. Achatina fulica, a giant African snail, is sliced and canned and
passed off on some consumers as escargot. Terms such as "garden snail" or "common
brown garden snail" are rather meaningless since they refer to so many types of snails,
but they sometimes mean H. aspersa.
- Helix aspersa Muller is also known as the French "petit gris," "small grey snail," the
"escargot chagrine," or "La Zigrinata." The shell of a mature adult has four to five
whorls and measures 30 to 45mm across. It is native to the shores of the
Mediterranean and up the coast of Spain and France. It is found on many British Isles,
where the Romans introduced it in the first century A.D. (Some references say it dates
to the Early Bronze Age.) In the early 1800's the French brought it into California
where it has become a serious pest. These snails are now common throughout the U.S.
It was introduced into several Eastern and Gulf states even before 1850 and, later
introduced into other countries such as South Africa, New Zealand, Mexico, and
Argentina. H. aspersa has a life span of 2 to 5 years. This species is more adaptable
to different climates and conditions than many snails, and is found in woods, fields,
sand dunes, and gardens. This adaptability not only increases H. aspersa's range, but
it also makes farming H. aspersa easier and less risky.
- Helix pomatia Linne measures about 45mm across the shell. It also is called the
"Roman snail," "apple snail," "lunar," "La Vignaiola," the German
"Weinbergschnecke," the French "escargot de Bourgogne" or "Burgundy snail," or
"gros blanc." Native over a large part of Europe, it lives in wooded mountains and
valleys up to 2,000 meters (6,000 feet) altitude and in vineyards and gardens. The
Romans may have introduced it into Britain. Immigrants introduced it into the U.S. in
Michigan and Wisconsin. Many prefer H. pomatia to H. aspersa for its flavor and its
larger size, as the "escargot par excellence."
- Otala lactea or Helix lactea is sometimes called the "vineyard snail," "milk snail," or
"Spanish snail." The shell is white with reddish brown spiral bands and measures
about 26 to 35mm in diameter. Many think it tastes better than H. aspersa.
- Iberus alonensis--the Spanish "cabretes" or "xona fina"--measures about 30mm
across the shell.
- Cepaea nemoralis--Helix nemoralis, the "wood snail," or the Spanish "vaqueta,"--
measures about 25mm across the shell. It inhabits Central Europe and was introduced
into and inhabits many U.S. states, from Massachusetts to California and from
Tennessee to Canada. Its habitat ranges widely from woods to dunes. It mainly eats
dead plant material, but it likes nettles and buttercups and will eat dead worms and
dead snails.
- Cepaea hortensis, or Helix hortensis, the "garden snail," measures about 20mm across
the shell and has distinct dark stripes. It is native to central and northern Europe.
Introduced into Maine, Massachusetts, and New Hampshire in colonial times, it never
became established in these states. Its habitat varies like C. nemoralis, but C.
hortensis is found in colder and wetter places than nemoralis. Their smaller size and
some people's opinion that snails with striped shells do not taste as good make
hortensis and nemoralis less popular.
- Otala punctata or Archelix punctata, called "vaqueta" in some parts of Spain,
measures about 35mm across the shell.
- Otala vermiculata--also called Eobania v. or Helix v., the "vinyala," "mongeta," or
"xona"--measures about 25mm. It is found in Mediterranean countries and was
introduced into Louisiana and Texas.
- Helix lucorum, sometimes called "escargo turc," measures about 45mm across the
shell. It is found in central Italy and from Yugoslavia through the Crimea to Turkey
and around the Black Sea.
- Helix adanensis comes from around Turkey.
- Helix aperta measures about 25mm. Its meat is highly prized. It is native to France,
Italy, and Mediterranean countries and has become established in California and
Louisiana. Sometimes known as the "burrowing snail," it is found above ground only
during rainy weather. In hot, dry weather, it burrows three to six inches into the
ground and becomes dormant until rain softens the soil.
- Theba pisana--also called the "banded snail"or the "cargol avellanenc"--measures
about 20mm and lives on dry, exposed sites, usually near the sea. Native to Sicily, it
has been spread to several European countries, including England. This snail is a
serious garden pest and is the "white snail" that California once eradicated by using
flamethrowers to burn off whole areas. In large numbers, up to 3,000 snails per tree, it
can ravage a garden in 24 hours and a citrus or other crop in a couple of nights.
- Sphincterochila candidisima or Leucochroa candidisima, the "cargol mongeta," or
"cargol jueu" measures about 20mm.
- Achatina fulica, one of several giant African snails, grows up to 326mm (one foot)
long. Its origin is South of the Sahara in East Africa. This snail was purposely
introduced into India in 1847. There was an unsuccessful attempt to establish it in
Japan in 1925. It has been purposely and accidentally transported to other Pacific
locations and was inadvertently released in California after World War II, in Hawaii,
and later in North Miami Florida in the 1970's. In many places, it is a serious
agricultural pest that causes considerable crop damage. Also, due to its large size, its
slime and fecal material create a nuisance as does the odor that occurs when something
like poison bait causes large numbers to die. The U.S. has made considerable effort to
eradicate Achatina. The U.S. Department of Agriculture (USDA) bans the
importation of, and it is illegal to possess, live giant African snails.
"There is no such thing as the giant African or West African snail since there are many
genera containing numerous species. . . . For instance, the giant snail in Ghana is
taken to mean Achatina Achatina (Linne), but in Nigeria this might refer to
Arachachatina Marginata (Swainson), and in East Africa to Achatina fulica Bodich.
There are, therefore, several giant land snails in Africa, and not just one species."

Snails are hermaphrodites. Although they have both male and female reproductive
organs, they must mate with another snail of the same species before they lay eggs.
Some snails may act as males one season and as females the next. Other snails play
both roles at once and fertilize each other simultaneously. When the snail is large
enough and mature enough, which may take several years, mating occurs in the late
spring or early summer after several hours of courtship. Sometimes there is a second
mating in summer. (In tropical climates, mating may occur several times a year. In
some climates, snails mate around October and may mate a second time 2 weeks later.)
After mating, the snail can store sperm received for up to a year, but it usually lays
eggs within a few weeks. Snails are sometimes uninterested in mating with another
snail of the same species that originated from a considerable distance away. For
example, a H. aspersa from southern France may reject a H. aspersa from northern
France.
Snails need soil at least 2 inches deep in which to lay their eggs. For H. pomatia, the
soil should be at least 3 inches deep. Keep out pests such as ants, earwigs, millipedes,
etc. Dry soil is not suitable for the preparation of a nest, nor is soil that is too heavy.
In clay soil that becomes hard, reproduction rates may decrease because the snails are
unable to bury their eggs and the hatchlings have difficulty emerging from the nest.
Hatchability of eggs depends on soil temperature, soil humidity, soil composition, etc.
Soil consisting of 20% to 40% organic material is good. Keep the soil 65 F to 80 F,
best around 70. Maintain soil moisture of 80%. One researcher removes eggs
immediately after they are deposited, counts them, then keeps them on moist cotton
until the eggs hatch and the young start to eat. Snails lose substantial weight by laying
eggs. Some do not recover. About one-third of the snails will die after the breeding
season.
H. pomatia eggs measure about 3mm in diameter and have a calcareous shell and a
high yolk content. H. pomatia lays the eggs in July or August, 2 to 8 weeks after
mating, in holes dug out in the ground. (Data varies widely on how long after mating
snails lay eggs.) The snail puts its head into the hole or may crawl in until only the top
of the shell is visible; then it deposits eggs from the genital opening just behind the
head. It takes the snail 1 to 2 days to lay 30 to 50 eggs. Occasionally, the snail will
lay about a dozen more a few weeks later. The snail covers the hole with a mixture of
the slime it excretes and dirt. This slime, which the snail excretes to help it crawl and
to help preserve the moisture in its soft body, is glycoprotein similar to eggwhite.
Fully-developed baby H. pomatia snails hatch about 3 to 4 weeks after the eggs are
laid, depending on temperature and humidity. Birds, insects, mice, toads and other
predators take a heavy toll on the young snails. The snails eat and grow until the
weather turns cold. They then dig a deep hole, sometimes as deep as 1 foot, and seal
themselves inside their shell and hibernate for the winter. This is a response to both
decreasing temperature and shorter hours of daylight. When the ground warms up in
spring, the snail emerges and goes on a binge of replacing lost moisture and eating.
H. aspersa eggs are white, spherical, about 3mm in diameter and are laid 5 days to 3
weeks after mating. (Data varies widely due to differences in climate and regional
variations in the snails' habitats.) H. aspersa lays an average of 85 eggs in a nest that
is 1- to 1 1/2-inches deep. Data varies from 30 to over 120 eggs, but high figures may
be from when more than one snail lays eggs in the same nest.
In warm, damp climates, H. aspersa may lay eggs as often as once a month from
February through October, depending on the weather and region. Mating and egg-laying begin
when there are at least 8 hours of daylight and continue until days begin to get shorter. In the
United States, longer hours of sunlight that occur when temperatures are still too cold will affect
this schedule, but increasing hours of daylight still stimulate egg laying. If warm enough, the
eggs hatch in about 2 weeks, or in 4 weeks if cooler. It takes the baby snails several more days
to break out of the sealed nest and climb to the surface. In a climate similar to southern California's,
H. aspersa matures in about 2 years. In central Italy, H. aspersa hatches and emerges
from the soil almost exclusively in the autumn. If well fed and not overcrowded, those snails
that hatch at the start of the season will reach adult size and form a lip at the edge of
their shell by the following June. If you manipulate the environment to get more early
hatchlings, the size and number of snails that mature the following year will increase.
In South Africa, some H. aspersa mature in 10 months, and under ideal conditions in a
laboratory, some have matured in 6 to 8 months. Most of H. aspersa's reproductive
activity takes place in the second year of its life.
By contrast, one giant African snail, Achatina fulica, lays 100 to 400 elliptical eggs
that each measure about 5mm long. Each snail may lay several batches of eggs each
year, usually in the wet season. They may lay eggs in holes in the ground like H.
pomatia, or lay eggs on the surface of a rocky soil, in organic matter, or at the base of
plants. In 10 to 30 days, the eggs hatch releasing snails about 4mm long. These snails
grow up to 10mm per month. After 6 months, the Achatina fulica is about 35mm long
and may already be sexually mature. Sexual maturity takes 6 to 16 months, depending
on weather and the availability of calcium. This snail lives 5 or 6 years, sometimes as
many as 9 years.

Within the same snail population and under the same conditions, some snails will grow
faster than others. Some will take twice as long to mature. This may help the species
survive bad weather, etc., in the wild. However, a snail farmer should obviously select
and keep the largest and fastest maturing snails for breeding stock. Sell the smaller
snails. By selecting only the largest, the average size of the snail may increase
significantly in only a couple of generations. Most of the differences in growth are
probably due to environmental factors including stocking density. However, to
whatever extent these differences are genetic, you might as well breed large, fast-growing
snails instead of small, slower-growing ones.
Several factors can greatly influence the growth of snails including: population
density; stress [snails are sensitive to noise, light, vibration, unsanitary conditions,
irregular feedings, being touched, etc.]; feed; temperature and moisture; and the
breeding technology used.
H. aspersa requires at least 3% to 4% calcium in the soil (or another source of
calcium) for good growth. Most snails need more calcium in the soil than H. aspersa.
Low calcium intake will slow the growth rate and cause the shell to be thinner.
Calcium may be set out in a feeding dish or trough so the snails can eat it at will. Food
is only one calcium source. Snails may eat paint or attack walls of buildings seeking
calcium, and they also will eat dirt.
A newborn's shell size depends on the egg size since the shell develops from the egg's
surface membrane. As the snail grows, the shell is added onto in increments.
Eventually the shell will develop a flare or reinforcing lip at its opening. This shows
that the snail is now mature; there will be no further shell growth. Growth is measured
by shell size, since a snail's body weight varies and fluctuates, even in 100% humidity.
The growth rate varies considerably between individuals in each population group.
Adult size, which is related to the growth rate, also varies, thus the fastest growers are
usually the largest snails. Eggs from larger, healthier snails also tend to grow faster
and thus larger.
Dryness inhibits growth and even stops activity. When it becomes too hot and dry in
summer, the snail becomes inactive, seals its shell and estivates (becomes dormant)
until cooler, moister weather returns. Some snails estivate in groups on tree trunks,
posts, or walls. They seal themselves to the surface thus sealing up the shell opening.

Successful snail culture requires the correct equipment and supplies, including: snail
pens or enclosures; devices for measuring humidity (hygrometer), temperature
(thermometer), soil moisture, and light (in foot candles); a weight scale and an
instrument to measure snail size; a kit for testing soil contents; and a magnifying glass
to see the eggs. You also may need equipment to control the climate (temperature and
humidity), to regulate water (e.g., a sprinkler system to keep the snails moist and a
drainage system), to provide light and shade, and to kill or keep out pests and
predators. Some horticultural systems such as artificial lighting systems and water
sprinklers may be adapted for snail culture. You will have better results if you use
snails of the same kind and generation. Some recommend putting the hatchlings in
another pen.
Four Systems: Snail farms may be outdoors; in buildings with a controlled climate;
or in closed systems such as plastic tunnel houses or "greenhouses." In addition,
snails may breed and hatch inside in a controlled environment and then (after 6 to 8
weeks) may be placed in outside pens to mature.
Climate: A mild climate (59-75 F) with high humidity (75% to 95%) is best for
snail farming, though most varieties can stand a wider range of temperatures. The
optimal temperature is 70 F for many varieties. When the temperature falls below
45 F, snails hibernate. Under 54 F the snails are inactive, and under 50 F, all
growth stops. When the temperature rises much above 80 F or conditions become too
dry, snails estivate. Wind is bad for snails because it speeds up moisture loss, and
snails must retain moisture.
Moisture: Snails need damp, not wet, environments. Although
snails need moisture, you must drain wet or waterlogged soil to make it suitable for them.
Similarly, rainwater must run off promptly. Snails breathe air and may drown in overly wet
surroundings. A soil moisture content of 80% of capacity is favorable. In the hours of
darkness, air humidity over 80% will promote good snail activity and growth.
Ninety-nine percent of snail activity, including feeding, occurs in the cool, dark
nighttime, with peak activity taking place 2 to 3 hours after darkness begins. The
cooler temperature stimulates activity, and the nighttime dew helps the snail move
easily. They hide in sheltered places during most of the day. If necessary, use misting
sprayers, like those used for plant propagation, in dry climates to maintain adequate
humidity and moisture levels.
Soil: Use a good medium soil that has neither a lot of sand
nor too much clay. Snails are unable to dig into hard, dry clay. Soils with too much
sand do not contain enough water. Soil that contains 20% to 40% organic matter is good.
The soil should be similar to that of a garden in which green, leafy vegetables thrive.
If your snail farm contains plants, keep them wet and properly care for them. Regularly
remove any weeds. Neutralize soil that is too acidic with lime to make it suitable (at about pH 7).
Besides the pH value of the soil, calcium must be available either from the soil or
another readily available source, since snail shells are 97% to 98% calcium carbonate.
If in doubt, you can add a little ground limestone. One researcher treats the soil with
polyacrylamide at the rate of 12.5cc of a 160-g M.A./one preparation in 250cc of
water per kilogram of dry soil. This stabilization treatment helps the soil structure
resist washing. This allows regular cleaning without destroying the crumb structure of
the soil that is beneficial for egg laying.
Snails dig in soil and ingest it. Good soil favors snail growth and provides some of
their nutrition. Lack of access to good soil may cause fragile shells even when the
snails have well-balanced feed; the snails growth may lag far behind the growth of
other snails on good soil. Snails will often eat feed, then go eat dirt. Sometimes, they
will eat only one or the other. This may be one reason that you should not crowd too
many snails into too small a pen. The soil, unless frequently changed, will become
fouled with mucus and droppings. Chemical changes also may occur in the soil. A
mixture of peat, clay, compost, CaCO3 at pH 7 makes a very good soil. Leaf mold at
pH 7 works almost as well. Organic matter in the soil seems as important as
carbonates. Soils that are richest in exchangeable calcium and magnesium stimulate
growth best. Usable carbonates and total calcium are important. Calcium may be
added to the soil at the rate of 10 pounds per 100 square feet. Calcium may also be set
out in a feeding dish or trough so the snails can eat it at will.
[Note: The U.S. Animal and Plant Health Inspection Service (APHIS) Standards for Snail-Rearing Facilities were revised March 2001 and are available at
http://www.aphis.usda.gov/plant_health/permits/index.shtml.]
Enclosures for snails are usually long and thin instead of square. This allows you to
walk around (without harming the snails) and reach in the whole pen. The enclosure
may be a trough with sides made of wood, block, fiber cement sheets, or galvanized
sheet steel. Cover it with screen or netting. The covering will confine the snails and
keep out birds and other predators. Fences or walls are usually 2-feet high plus at least
5 inches into the ground. Fencing made of galvanized metal or hard-plastic sheets
helps keep out some predators. A cover will protect against heavy rain. Shade (which
may be a fine mesh screen) on warm winter days helps keep the snails dormant. Use
5mm mesh or finer for pen screens or fences. Pens containing baby snails will need a
finer mesh.
Snails like hiding places, especially during the warm daytime. For example, purchase
plastic soil drainage pipes from the local garden center, split them in two lengthwise,
and stack one layer one way and the next layer at a right angle. This will provide
shelter and will increase by 50% the number of snails you can put in the pen.
A sprinkler system will ensure moisture when needed. Turn it on at sunset. If turned
on early in the day, the moisture may drive snails out into hot sunshine. Monitor
temperature and humidity using a thermometer and a hygrometer.
Although you can use fencing for the enclosure's sides, the bottom, if not the ground
or trays of dirt, must be a surface more solid than screening. A snail placed in a wire-mesh-bottom
pen will keep crawling, trying to get off the wires and onto solid, more comfortable ground.
Preventing escapes: In an open pen, curve the top of the fences inward in a half
circle to confine the vineyard snail. H. aspersa will escape from such an open pen, so
you could use an electric fence to contain them. [The electric fence top has two or
more thin wires that are 2 to 4mm apart. Each wire carries the opposite charge of the
wire next to it. Use a battery or transformer to supply 4 to 12 volts to the wire. A snail
will get a mild shock and retract when it crawls over a wire and touches a second
wire.]
Another technique to confine snails is to bend the fence top inward into a sharp "V"
shape with about a 20 angle. The snail's shell will hit the bent-back part of the screen
before he can reach up and start crawling on it. This blocks him, and the angled
screen automatically compensates for the size of the snail.
Another alternative, especially handy for solid wall enclosures, is to attach to the wall
a horizontal piece of screen that projects inward several inches over the enclosure.
Make the screen with material like nylon monofilament that is moderately stiff and
springy yet easily flexible. On the inside edge of the screen, remove the cross fibers
until you've created a fringe several inches wide. As the would-be escapee crawls on
the underside of the screen and moves out onto the fringe, his weight pulls several
individual fibers down. One by one, another fiber gets away from the snail and
springs back up out of reach. Eventually the snail is dangling by a thread. He then
falls because the surface area is not big enough to crawl on.
Since snails usually will not cross a copper band, another solution is to top the fence
with 3-inch-wide (or wider) copper band. You could bend the band so that part of it
faces inward and is parallel to the pen floor. If the band is placed too close to the
ground, rain may wash soil against the copper and leave a residue that may enable the
snail to cross it. Also, be sure to bury the bottom of the fence deep enough into the
ground so that the snails don't dig under it.
Pens with gardens: An alternate method is to make a square
pen with a 10-foot-square garden in it. Plant about six crops, e.g., nettles and artichokes,
inside the pen. The snails choose what they want to eat. If it has not rained, turn sprinklers
on for about 15 minutes at dusk, unless the snails are dormant. A disadvantage to this
method is that, if the snails are not mature at the end of the year, it is difficult to replant
fresh plant crops in the pens.
Plastic tunnels make cheap, easy snail enclosures, but it is
difficult to regulate heat and humidity. The tunnel will be 10 to 20 warmer than the outside,
and snails become dormant as the temperature climbs above 80 F.
Indoor pens: With snails raised indoors under controlled
conditions, reproduction varies according to the geographic origin of the breeding stock.
For example, one researcher found that H. aspersa snails from Brittany seem to
do better indoors than snails from another region. To breed snails indoors, keep the
temperature at 70 F. and the relative humidity at 80% to 90%; some sources say 95%.
Another source recommends 75% humidity by day and 95% at night. The Center for
Heliciculture once recommended 65-75% humidity during the day and 85-95% at night
at 68 F. In any event, avoid humidity higher than 95% (some say 90%) for any length
of time. Excessive humidity can kill snails. Optimum temperature and relative humidity
depend on several things, including the snail variety and even where breeding stock
was gathered. For H. aspersa, the optimum temperature for hatching eggs seems to be
68 F at 100% relative humidity. The second best temperature/humidity combination
depends on where the snails came from and results can drop drastically to 0% hatching
at 62.6 F and 100% humidity. Err on the side of a few degrees warmer or a small
percentage dryer. Do not keep the soil wet when the humidity is maintained at 100%,
as the eggs will absorb water, swell up, and burst.
Use fluorescent lights to give artificial daylight. Different snails respond differently to
day length. The ratio of light to darkness influences activity, feeding, and mating andegg-laying. Eighteen or more hours of light apparently stimulate H. aspersa growth,
while less than 12 hours inhibit it. Some snail species may associates the long hours
of light with the start of summer--the peak growing season. Eighteen hours of
daylight also appear optimal for breeding (mating and egg laying), but snails will
breed in darkness.
Breeding boxes and cages: Snails can be bred in boxes or
cages stacked several units high. Use an automatic sprinkler system to provide moisture.
Breeding cages should have a feed trough and a water trough. Plastic trays that are a
couple of inches deep are adequate; deeper water troughs increase the chance of
snails drowning in them. These trays may be set on a bed of small gravel. Fill small
plastic pots, e.g., flower pots about 3 inches deep, with sterilized dirt (or a loamy pH
neutral soil) and set them in the gravel to give the snails a place to lay their eggs.
Remove and replace each pot after the snails lay eggs. (Set one pot inside another
so that you can easily lift one out without shifting the gravel.)
After the snails have laid their eggs, put the pots in a nursery where the eggs will
hatch. Keep the young snails in the nursery for about 6 weeks. Then move them to a
separate pen as young snails do best if kept with other snails of similar size. Eight
hours of daylight is optimal for young snails.
The following is an example of starting H. pomatia in boxes:
Build wooden boxes measuring 25 by 35cm and 25cm high. Cut a 6cm-diameter hole (to
drain excess moisture) in the bottom and cover the hole with plastic screening, well secured.
Cover a frame with plastic screening to create the box lid. The lids either must open or be
removable. Keep the boxes on shelves so they are easily accessible. Fill the boxes
one-third full with loose, uncompacted garden soil baked to kill all organisms (insects,
nematodes, bacteria, etc.). [Use soil that does not have fertilizer or chemicals in it.]
Partially cover the soil with moss, but leave enough room for the snails to crawl around on
the dirt. Sprinkle water on the moss.
Move to boxes (three per box) those snails in the outdoor pen that are starting to make
holes in which to lay their eggs. After the snails lay eggs, return them to the outside
pen. The soil in the boxes must not dry out. Always keep the moss slightly moist.
Too much moisture is dangerous, however, as the eggs may swell up and burst. The
eggs hatch in about 25 days, but the baby snails remain in the egg "shells." They then
work their way out of the nest for about 10 additional days before they appear on the
moss and on the sides of the box. Snails on the wood sides of the box are in danger of
drying out and must be carefully removed and put on the moss. Shells are very fragile
at this time.
Feed the baby snails tender lettuce leaves (Boston type, but head type is probably just
as good.) [This description does not include a water trough, but the authors assume
there is one. The snails should have water available.]
Three weeks after the snails appear on the moss, carefully remove the baby snails and
put them together in a temporary container. Carefully remove the moss and dirt,
watching for any more baby snails. Replace the dirt and moss with fresh
(sterilized/baked) dirt and fresh moss. Count and return the snails to the box.
The young snails can be kept over winter in these boxes. Stack the boxes in a cool
room protected from frost. The room should never get colder than 32 F nor warmer
than 37.4 F. Snails will become active again the following spring when the
temperature rises above 41 F. Feed them for 4 weeks. They should now average
about 8mm. Move them to a pen, carefully clean and dry the boxes, and prepare the
boxes for the new season. H. pomatia matures in 18 months to 4 years.
Mixed system: A variation of the method above is to let the
snails lay the eggs in the outdoor pen, then carefully transfer the eggs to the boxes.
[The other steps are the same.] In the pen, look for snails that have dug holes and
are in them laying eggs. The tip of their shell will be visible. Stick a marker in the ground
next to the hole. When the snail is finished and leaves, use a garden trowel to dig up the
eggs and move them. This task is difficult. The eggs can be both physically damaged
and covered with dirt.
Example: Five stages of snail raising
Some who raise H. aspersa separate the five stages: reproduction, hatching, young,
fattening, and final fattening.
In a typical example, the breeding box has concrete sides, soil with earthworms (to
cleanse the soil) on the bottom, vegetation, curved tiles to provide shelter, feeders, and
a chicken waterer. Mosquito netting or screening covers the top. These breeding
boxes may be outside, or you may get better results when the boxes are inside a
greenhouse--as long as the greenhouse does not get too hot or too dry. One
researcher reported that in outdoor boxes, each breeder snail had about seven young.
In greenhouses, each breeder snail had about 9 to 12 young. The researcher felt that
under better weather conditions than those he had that year, each adult breeder snail
would have produced 15 young snails.
Fattening pens may be outside or in a greenhouse. High summer temperatures and
insufficient moisture cause dwarfing and malformations of some snails. This is more a
problem inside greenhouses if the sun overheats the building. A sprinkler system (e.g.,
a horticultural system or common lawn sprinklers) can supply moisture. Make sure
excess water can drain.
Fattening pens may contain 2-foot by 3-foot pieces (or other convenient size) of heavy
plastic sheets, hung from boards resting on a rack that lets the tips of the plastic sheets
just touch the ground. The plastic sheets are about 4 inches apart. The sheets give the
snails a resting and hiding place. Feeders may be located on the rack that supports the
plastic sheets.
Put a layer of coarse sand and topsoil with earthworms on the fattening pen's bottom.
The worms help clean up the snail droppings.
You can put snails that hatched the previous summer in a chilled room for hibernation
over winter. Then, about the 1st of April, (adjusted for your local climate), move them
to the final fattening pen. If you have several fattening pens, put the smaller snails in
one, medium in another, large in another. Do not exceed one-third pound of H.
aspersa snails per square foot of pen. Since snails lose weight when they estivate in
summer, some growers do not stock pens by weight but by count. For H. aspersa, 10
to 12 snails per square foot is about the maximum.
Breeding pens can be set up just like the fattening pens or the fattening pens can be
used as breeding pens after you harvest the mature snails. Harvest some snails and
leave some to breed.
The first snails to hatch eat the shells of their eggs. This gives them needed calcium
for their shells. They may then begin eating unhatched eggs. If the snail eggs are kept
at the optimum temperature, 68 F (for some varieties), and if none of the eggs lose
moisture, most eggs will hatch within 1 to 3 days of each other. Cannibalism also will
be low. If hatching extends over a longer period, cannibalism may increase. Some
eggs eaten are eggs that were not fertile or did not develop properly, but sometimes,
properly developing embryos might be eaten. A high density of "clutches" of egg
masses increases the rate of cannibalism, as other nearby egg masses are more likely to
be found and eaten. Snail egg has 12 to 20 times the protein of salad. The protein
helps the baby snails start developing quickly and be healthier. Snail egg is an
excellent starter food for newly hatched snails, but they tend to only eat eggs of their
own species.
Besides farming snails, it is possible to gather them free from artichoke, kiwifruit,
avocado, and citrus growers in some areas. The growers might pick the snails for you
for a fee. In citrus groves where copper bands have been placed around the tree
trunks, the snails will crawl up the tree to feed on the leaves. They will stop when they
come to the copper band and will remain there for days. The snails gathered just
below the band are easy to pick off.
Snails gathered in the wild to stock a snail farm may have a high mortality rate as they
adjust to the new conditions. These snails may have consumed poison baits,
agricultural chemicals, or poisonous plants (e.g., nightshade); therefore, you should
not immediately use them. Put them in a pen and feed them for at least 3 days to
purge their system of any toxins and to give them a chance to die if they have
consumed a lethal dose. If they are still healthy after 3 or 4 days, they should be O.K..
Withhold all food, except water, for the last 1 to 2 days.
Feeding season is April through October, (or may vary with the local climate), with a
"rest period" during the summer. Do not place food in one small clump so that there is
not enough room for all the snails to get to it. Snails eat solid food by rasping it away
with their tongues. Feeding activity depends on the weather, and snails may not
necessarily feed every day. Evening irrigation in dry weather may encourage feeding
since the moisture makes it easier for the snails to move about.
Put the breeding snails in the breeding pens in April or early May. Feed until mid
June when mating begins and the snails stop feeding. Snails resume eating after they
lay eggs. Once snails have laid their eggs, you can remove the adult snails. This
leaves more food and less crowding for the hatchlings.
Snails of the same species collected from different regions may have different food
preferences. Some foods that snails eat are: Alyssum, fruit and leaves of apple,
apricot, artichoke (a favorite), aster, barley, beans, bindweed, California boxwood,
almost any cabbage variety, camomile, carnation, carrot, cauliflower, celeriac (root
celery), celery, ripe cherries, chive, citrus, clover, cress, cucumbers (a favorite snail
food), dandelion, elder, henbane, hibiscus, hollyhock, kale, larkspur, leek, lettuce
(liked, and makes good snails), lily, magnolia, mountain ash, mulberry, mums,
nasturtium, nettle, nightshade berries, oats, onion greens, pansy, parsley, peach, ripe
pears, peas, petunia, phlox, plum, potatoes (raw or cooked), pumpkins, radish, rape,
rose, sorrel, spinach, sweet pea, thistle, thornapple, tomatoes (well liked), turnip,wheat, yarrow, zinnia. They will eat sweet lupines, but will reject bitter lupines and
other plants with high quinolizidine alkaloids. Snails also avoid plants that produce
other defensive chemicals, defensive stem hairs, etc.
Snails usually prefer juicy leaves and vegetables over dry ones. If you feed snails
vegetable trimmings, damaged fruit, and cooked potatoes, promptly remove uneaten
food as it will quickly spoil. You may supply bran that is wet or sprinkle dry bran
over leafy vegetables. The diet may consist of 20% wheat bran while 80% is fruit and
vegetable material. Some growers use oats, corn meal, soybean meal, or chicken
mash. Laying mash provides calcium, as does crushed oyster shells. Snails also may
eat materials such as cardboard (but do not purposely feed it to them); they can eat
through shipping cartons and escape. Snails may sometimes eat, within a 24-hour
period, food equal to 10%, and occasionally as much as 20%, of their body weight.
Active snails deprived of food will lose more than one-third of their weight before they
starve to death--a process that takes 8 to 12 weeks. Estivating snails can survive
much longer.
Supply calcium at least once a week if it is not available in the soil. It should not
contain harmful salts or be so alkaline as to burn the snails. Mix calcium with wet
bran or mashed potatoes and serve on a pan; this will keep any leftover food from
rotting on the ground.
Some researchers use chicken mash for feed. You can cut a plastic pipe in half
lengthwise to make two troughs which can be used as feeders for mash. Mix laying
mash (used for egg-producing hens) into the feed to provide calcium for the snails'
shells. Commercial chicken feeding mash is around 16% to 17% protein, from fish
meal and meat meal, making it good for growing snails. Supplying mash to hatchlings
might reduce cannibalism. Two feeds that snails like and that promote good growth
are: (A) broiler finisher mash consisting of 7% broiler concentrate, 58% corn, 16%
soya, 18% sorghum, 7 % limestone flour (40% Ca); and (B) chicken feed (pellets) for
layers consisting of 5% layer concentrate, 10%, corn, 15% soya, 20% sorghum, 44%
barley, 6% limestone flour (40%Ca).
Pellets are fine for larger snails, but mash is better for younger ones. Partially crush
pellets if you feed them to young snails. Snails do not grow well if rabbit pellets are
their primary diet. Snails show a distinct preference for moist feed. Ensure easy
access to enough water if you feed snails dry mash.
Be sure to frequently clean the feed and water dishes. The amount of feed a snail eats
depends very much on air humidity and on the availability of drinking water. You can
serve clean drinking water in a shallow container to reduce the risk of the snail
drowning. Some types of chicken waterers may be suitable. Other factors (e.g.,
temperature, light intensity, food preferences versus food supplied, etc.) also affect
feeding. A compromise, until you find the optimum feed, is to feed half green
vegetable material and half chicken feed/grain/animal protein.
Young H. aspersa readily eats milk powder. Its rapid rate of assimilation promotes
rapid growth.
Basic common sense hygiene may prevent the spread of disease or otherwise improve
the health and growth rate of snails. For example, remove and replace food daily to
prevent spoilage. Earthworms added to the soil will help keep the pen clean.
Parasites, nematodes, trematodes, fungi, and microarthropods may attack snails, and
such problems can spread rapidly when snail populations are dense. The bacterium
Pseudomonas aeruginosa causes intestinal infections that can spread rapidly in a
crowded snail pen.
Watch for predators such as: rats, mice, moles, skunks, weasels, birds, frogs and
toads, lizards, walking insects (e.g., some beetle and cricket varieties), some types of
flies, centipedes, and even certain cannibalistic snail varieties (such as Strangesta
capillacea).
Population density also affects successful snail production. Pens should contain no
more than six to eight fair-sized snails per square foot, or about four large H.
pomatias; or figure one kilogram per square meter (about .2 pounds of snail per square
foot), which automatically compensates for the size of the snails. If you want them to
breed, best results will occur with not more than eight snails per square meter (.8 snails
per square foot). Some sources say that, for H. pomatia to breed, .2 to .4 snails per
square foot is the maximum.
Snails tend not to breed when packed too densely or when the slime in the pen
accumulates too much. The slime apparently works like a pheromone and suppresses
reproduction. On the other hand, snails in groups of about 100 seem to breed better
than when only a few snails are confined together. Perhaps they have more potential
mates from which to choose. Snails in a densely populated area grow more slowly
even when food is abundant, and they also have a higher mortality rate. These snails
then become smaller adults who lay fewer clutches of eggs, have fewer eggs per
clutch, and the eggs have a lower hatch rate. Smaller adult snails sell for less.
Dwarfing is quite common in snail farming and is attributable mainly to rearing
conditions rather than heredity factors. Crowding snails is false economy. A
recommended rate for H. aspersa is not more than one-third pound per square foot of
soil surface for snails that weigh more than 1 gram and not more than .2 pound per
square foot for snails that weigh less. (One ounce is about 28 grams.)

Select only active snails for canning, processing or shipping. An inactive snail may be
sick or dying. It is best to ship live snails (laws permitting) while dormant, between
late Fall and early March, although it is then difficult to be sure they are "active."
Inspect each snail to be sure it looks healthy. Put them in a container packed in ice to
keep the temperature near (but not below) freezing to keep the snails dormant. When
the weather warms up and the snails are active, they cannot be packed so closely in
cartons. As live animals, you must handle them humanely. Some sources say not to
ship live snails (H. pomatia) after June begins, as they no longer have good flavor.
H. aspersa has a fragile shell until it matures and forms a lip, so immature snails are not commercially desirable.
Snails tend not to eat during shipping. Do not provide food, as it will spoil and may
make the snails sick or die. Purge the snails' digestive tracts to ensure that they are
clear of grit or previously-eaten food. Three or 4 days before transporting, put the
snails in a separate container without dirt or other kinds of food. Feed the snails
cornmeal or bran for several days. As it passes through the digestive tract, it will clean
out previously-eaten food. Stop feeding, but continue to supply water. Clean the pens
and snails several times a day to keep out mucus and fecal matter.
Shipping cartons must have air holes, preferably screened to prevent escape or injury
to the snails. Be careful not to injure snails with wires or staples when closing the
carton. Also remember, snails can push upward against a barrier with a force equal to
several times their own weight. Enough snails may cause the carton lids to pop off
and may even loosen nails.

Snails are mature when a lip forms at the opening of their shell. Before they mature,
their shells are more easily broken, making them undesirable. For H. aspersa,
commercial weight is 8 grams or larger.
The nutrient composition of raw snails (per 100 grams of edible portion), according to
information from the nutrient databank of France, is:
Energy (kcal): 80.5
Water (g): 79
Protein (g): 16
Available carbohydrates (g): 2
Fibres (g): 0
Fat (g): 1
Magnesium (mg): 250
Calcium (mg): 170
Iron (mg): 3.5
Vitamin C (mg): 0
Snails are washed, steamed, shelled, then washed in a vinegar- (or lemon juice) and
water-solution before they are canned. Producing a quality canned product is
somewhat tricky, and you must take care to prevent food poisoning. To prepare live
snails for cooking, remove the membrane, if any, over the shell opening. Soak the
snails in enough water to cover them. (Add 1/2-cup salt or 1/4-cup vinegar for every
50 snails.) Mucus will turn the water white. Change the water several times during
the 3- to 4-hour soaking. Rinse several times or under running water until no mucus
remains. Put snails in cold water and bring to a boil. Boil about eight minutes, then
drain and plunge the snails into cold water. Drain. With a needle or small fork, pick
the snails out of their shells. Remove the intestine and cut off all black parts. (Some
cooks also cut off the head, tail, and all "cartilage or gristle.") Prepare according to
your recipe. An alternate method is: Wash the snails well in clear water. Drop into
boiling salt water (to which you may add lemon juice and/or herbs), and cook--about
10-15 minutes--until you can easily remove the snails from their shells. Drain and
rinse.
Prepare the giant African snail by breaking away the shell, then cutting the foot away
from the rest of the body. The traditional way to remove the slime is to rub wood
ashes on the snail, then wash the snail (or part of the snail) under running water, then
repeat until no slime remains. You may substitute substances like flour (to which you
may add salt and vinegar) for ashes. Cut up the foot into convenient-sized pieces.
[You may dehydrate the leftover visceral mass, crush it up with the shell, and mix it in
poultry feed to make up 10% of your snail feed.] Another source says put the live
snails in boiling water for 30 minutes to kill them and to make removal from the shell
easy. During boiling, the snails will release a large quantity of mucus. Data varies,
but 28% to 46% of the live weight of Achatina is shell.

The same snails that some people raise or gather as food also are agricultural pests that
cause considerable crop damage. Introduced slug and snail varieties tend to be worse
pests than native species, probably due in part to the lack of natural controls. Snail
pests attack crops ranging from leafy vegetables to fruits that grow near the ground,
such as strawberries and tomatoes, to citrus fruits high up on trees.
The Federal Plant Pest Act defines a plant pest as "any living stage (including active
and dormant forms) of insects, mites, nematodes, slugs, snails,
protozoa, or other invertebrate animals, bacteria, fungi, other parasitic plants or reproductive parts
thereof; viruses; or any organisms similar to or allied with any of the foregoing; or any
infectious substances, which can directly or indirectly injure or cause disease or
damage in or to any plants or parts thereof, or any processed, manufactured, or other
products of plants..." The Animal Plant Health and Inspection Service (APHIS)
categorizes giant African snails as a "quarantine significant plant pest." The United
States does not allow live giant African snails into the country under any
circumstances. It is illegal to own or to possess them. APHIS vigorously enforces this
regulation and destroys or returns these snails to their country of origin. For more information, see APHIS Permits: Snails and Slugs, or the National Invasive Species Information Center Species Profile: Giant African Snail.
Since large infestations of snails can do devastating damage, many states have quarantines against nursery products, and other products, from infested states. Further, it is illegal to import snails (or slugs) into the U.S. without permission from the Plant Protection and Quarantine (PPQ) Division, Animal Plant Health and Inspection Service, U.S. Department of Agriculture. For more information, contact Plant Pest Evaluations Toll Free Telephone: 866-524-5421. APHIS also oversees interstate transportation of snails. To import snails into the U.S. and/or move them interstate, download application or apply on-line for an APHIS PPQ 526 Plant Pest Permit at http://www.aphis.usda.gov/permits/ppq_epermits.shtml. To access the on-line permitting system, create a level 2 eAuthentication account at https://eauth.sc.egov.usda.gov/eAuth/selfRegistration/selfRegLevel2Step1.jsp. To complete the level 2 eAuthentication process, contact your nearest local registration authority, which can be found at http://offices.sc.egov.usda.gov/locator/app.
The Food and Drug Administration (FDA) regulates the canning
of low-acid foods such as snails. According to FDA, "establishments engaged in the
manufacture of Low-acid or Acidified Canned Foods (LACF) offered for interstate commerce
in the United States are required. . .to register their facility. . .and file scheduled processes for
their products with" the FDA. This does not refer to fresh products. For appropriate forms,
contact: LACF Registration Coordinator, HFS-618, Food and Drug Administration, Center
for Food Safety and Applied Nutrition, 200 C Street, S.W., Washington, D.C. 20204.
Telephone: (202) 205-5282. FAX: (202) 205-4758 or (202) 205-4128.
Improper canning of low-acid meats, e.g., snails, involves a risk of botulism. When
canning snails for home consumption, carefully follow canning instructions for low-acid
meats to prevent food poisoning.
State laws also may apply to imports into certain states and to raising snails in a given
state. Your state also may want to inspect and approve your facility. Thus anyone
who plans to raise snails also should check with their State's Agriculture Department.

Royal Society of Medicine Services] 25, no. 4 (October 1991): 291-298. Includes
references.
Abstract: Food intake, growth and protein utilization were studied in the Helix aspersa snail
by means of a nutritional balance experiment. This was designed in a 5 X 11 factorial
arrangement involving 5 diets of different protein content (10.0, 12.5, 15.0, 17.5 and 20.0%)
and 11 animal ages (ranging over 15 to 180 days of age). Dietary protein content and animal
age determined food intake and protein utilization. The variations of dry matter and protein
intake rates, growth rates, growth efficiency factors and protein retention rates, depending on
dietary protein content or animal age were in agreement with what happens in other animals.
These results suggest that there is no need to use diets with more than 17.5% of crude protein
in these animals. XAU: Animal Estacion Experimental del Zaidin (CSIC), Granada, Spain.
