The Atlantic salmon and brown trout (Salmo trutta) are widespread species and have been introduced worldwide as farmed food fish or recreational game fish, while most of the other Salmo species are narrowly distributed forms endemic to single watersheds. The name Salmo derives from the Latin salmō, meaning salmon.
The brown trout (Salmo trutta) is a species of salmonid ray-finned fish and the most widely distributed species of the genus Salmo, endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range.
However, once they return to freshwater, they quickly take on the normal coloration of resident brown trout in preparation for spawning. Sea trout kelts (post spawn) return to their silvery stage as they migrate back to saltwater. [9] Adult brown trout are between 35 and 60 cm (14 and 24 in) long, and can weigh from 0.5 to 2.4 kg (1.1 to 5.3 lb).
When in shared breeding habitats, Atlantic salmon will hybridize with brown trout (Salmo trutta). [26] [27] [28] Hybrids between Atlantic salmon and brown trout were detected in two of four watersheds studied in northern Spain. The proportions of hybrids in samples of salmon ranged from 0 to 7-7% but these proportions were not significantly ...
The genus Salmo contains the Atlantic salmon, found in both sides of the North Atlantic, as well as more than 40 other species commonly named as trout. The genus Oncorhynchus contains 12 recognised species which occur naturally only in the North Pacific, six of which are known as Pacific salmon while the remainder are considered trout.
