Water and Fisheries
Fish Species Introduction
The fresh waters of the world make up only about three percent
of all the water on Earth. Yet they represent a great variety of
habitats, from small ponds to deep lakes, fast flowing brooks to
sluggish rivers, still canals and ditches, foaming waterfalls, and
dark underground pools and streams. Fish have adapted to all of
these different habitats. There are over 20,000 species of bony
fishes in the world but only 109 species in Oregon and of those
there are 24 in Central Oregon.
People have fished since pre-historic times as indicated by fossil
finds from the stone age (30,000 years). In the medieval times,
fish flesh was a valuable addition to the weekly diet and in fact
monks kept carp and other fish protected in isolated ponds known
as “stew ponds”.
