Knowra Brown trout Brown trout Brown trout (Salmo trutta) are salmonid fish native to Europe and western Asia. They include migratory and resident forms and have been introduced widely beyond their native range.
Salmonidae : Salmonidae is a family of ray-finned fishes that includes salmon, trout, chars, and freshwater whitefishes. Brown trout belong to this family, alongside salmon and other trout.
Salmonid spawning : Salmonid spawning is the release and fertilization of eggs in freshwater, typically in nests called redds. Brown trout females excavate redds where eggs are deposited and fertilized.
Trout fishing : Trout fishing is the recreational or commercial capture of trout using methods such as angling, nets, or traps. Brown trout are a valued target for recreational anglers across their native and introduced ranges.
Introduced species : An introduced species is an organism transported by humans beyond its native range and established in a new area. Brown trout were deliberately introduced to many regions outside Europe and western Asia.
Rainbow trout : Rainbow trout (Oncorhynchus mykiss) are salmonid fish native to the Pacific coast of North America and northeastern Asia. They are a widely introduced trout often confused with brown trout, but belong to a different genus.
Salmo trutta : Salmo trutta is the scientific species name for brown trout and its recognized forms. This name encompasses the species’ diverse resident and migratory populations.
Redd : A redd is a gravel nest excavated by a female salmonid for depositing eggs. Brown trout bury their eggs in redds, where flowing water supplies oxygen.
Fly fishing : Fly fishing is angling with an artificial fly cast using a weighted line. Brown trout are a major target of fly fishing in rivers and lakes.
Brown trout in New Zealand : Brown trout in New Zealand are introduced populations established after nineteenth-century transfers from Europe. They became widespread and support major recreational fisheries, while affecting native freshwater ecosystems.
Brook trout : Brook trout (Salvelinus fontinalis) are char native to eastern North America. Despite their name, they are chars rather than close relatives of brown trout.
