The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. [19][20], First feeding of newly emerged fry is very important for brown trout survival in this phase of the lifecycle, and first feeding can occur even prior to emergence. [citation needed] Over time, this leads to reduction of the population of adult fish in the areas affected by the algae, forming a circle of decline. [34] Outside the U.S. and outside its native range in Europe, introduced brown trout have created "world-class" fisheries in New Zealand,[35] Patagonia,[36] and the Falklands.

Other names for anadromous brown trout are sewin (Wales), peel or peal (southwest England), mort (northwest England), finnock (Scotland), white trout (Ireland) and salmon trout (culinary). [24] Brown trout have had serious negative impacts on upland native fish species in some of the countries where they have been introduced, particularly Australia.

The species was originally named by German naturalist and taxonomist Johann Julius Walbaum in 1792 based on type specimens from the Kamchatka Peninsula in Siberia. [citation needed], In small streams, brown trout are important predators of macroinvertebrates, and declining brown trout populations in these specific areas affect the entire aquatic food web. Salmo fario Linnaeus, 1758; Salmo lacustris (non Linnaeus, 1758) Salmo trutta (non Linnaeus, 1758) International Common Names. [29] In the early 20th century, British angler and author G. E. M.
