Over 1,200 native fish species inhabit the freshwater rivers, streams, and lakes of the United States and Canada. About 95% of these species are non-game species such as darters, minnows, and dace. Nongame fishes are an important ecological link in the food chain, feeding on insects and serving as prey for sport fishes, birds, and other wildlife. This publication describes the biology of freshwater fish and conservation concerns.
