Taxonomic Grouping.

reproductive population status of the species in this location

Established- population is reproducing and overwintering
Reported- species seen; reproduction is not known - this is default status; many of these are actually established populations.
Failed- population was stocked but died out; failed to reproduce; or was eliminated.

To search for records occurring during a single year, enter the year in both boxes.

Otherwise, enter a starting and ending year.

The year range is inclusive (meaning that the starting and ending years will be included in the results).

salinity of introduction location.

Freshwater- introduced into areas of low salinity.
Marine/Brackish- introduced into areas of medium to high salinity

(also called vector) mechanism responsible for bringing the species to the new location.

Stocked- species was intentionally planted in the new location; i.e., stocked for sport, forage, stock contamination, biocontrol; includes legal and illegal stocking
Shipping- ballast water discharge and/or hull fouling
Aquarium release- species traditionally kept in aquaria (fish, snails) released into the wild by owners who no longer want them; can include escapes from aquaculture for locations in Florida since it is often impossible to distinguish between the two pathways in this area
Bait release- species introduced as discarded bait
Aquaculture- species that escaped from aquaculture facilities
Canals- species that gained access to new areas via canals
Pet Escape- species that were released by pet owners; species other than fish, snails
