Trout
Trout are freshwater fish in the salmon family, generally associated with cool streams and lakes. They are valued as food and sport fish.
Salmonidae: Salmonidae is the fish family that includes salmon, trout, char, and whitefish. Trout belong to this family, whose members share distinctive anatomy and life histories.
Salmonid spawning: Salmonid spawning is the reproduction process in which adults deposit and fertilize eggs in freshwater nests. Female trout dig gravel nests, called redds, where eggs are fertilized and develop.
Trout fishing: Trout fishing is the capture of trout for recreation or food, using methods such as fly fishing and bait fishing. Angling has shaped trout management and introduced many people to freshwater ecosystems.
Rainbow trout: Rainbow trout are a North American salmonid species, Oncorhynchus mykiss, with a characteristic pink lateral band. This widely introduced species is central to recreational fishing and aquaculture.
Salmon: Salmon are salmonid fishes, many of which migrate between rivers and the sea. Salmon are trout’s closest familiar relatives and share many biological traits.
Redd: A redd is a gravel nest made by a salmonid female for depositing eggs. Trout spawning depends on clean, oxygenated gravel in a suitable stream bed.
Fly fishing: Fly fishing is angling with an artificial fly cast using a weighted line. It is a widely practiced method for catching trout in streams and lakes.
Brown trout: Brown trout are a European salmonid species, Salmo trutta, established in waters worldwide. Its introduced populations illustrate how trout can reshape local freshwater communities.
Char: Char are salmonid fishes in the genus Salvelinus, including Arctic char and brook trout. Char are often confused with trout and occupy many of the same cold waters.
Parr: A parr is a juvenile salmonid marked by dark vertical bars along its sides. Young trout often spend months or years in this stream-dwelling stage.
