 Trout - Wikipedia, the free encyclopedia
Trout is the common name given to a number of species of freshwater fish belonging to the salmon family, Salmonidae.
Trout are usually found in cool, clear streams and lakes, and are distributed naturally throughout North America, northern Asia and Europe.
Because of their popularity, trout are often raised on fish farms and planted into heavily fished waters in an effort to mask the effects of overfishing.

The petitioners further assert that the BCT should be listed as threatened because the subspecies' present distribution and abundance are substantially reduced from historic conditions; remaining stocks are small, widely separated, and continue to decline in abundance; and the threats to the survival of BCT are pervasive and ongoing.
It has been further hypothesized that fluvial cutthroat trout may migrate to headwater reaches of streams to spawn, where hatched larvae may be either outside the range of contaminated reaches or amidst habitat conditions where the tubifex worms and spores may not or are less likely to accumulate in damaging or lethal concentrations.
In addition, native cutthroat trout management is discussed and the group provides a forum for developing standards on different issues such as assessing purity, chemical treatments for restoration, brood source development, inter- and intra-basin transfers, and stocking protocols.
