ນິເວດວິທະຍາຂອງ Salmo trutta

ການອ້າງອີງຫຼັກ	Muus, B.J. and P. Dahlström, 1967
ຂໍ້ສັງເກດ	Brown trout are territorial and begin establishing territories as juveniles (Ref. 26526). Juvenile trout from lake populations move from their natal inlets to lakes during the first 2 years of life (Ref. 6390). For sympatric populations of this species and Gadopsis marmoratus, coexistence was possible, although their diets were similar, because each species occupied different habitats (Ref. 26860). Juveniles feed mainly on larvae of insects; adults feed on crustaceans and fish (Ref. 51442). Fingerling brown trout seems to act as an opportunistic predator, and the consumption of different preys seems to be influenced by their accessibility, predation risk, and their energetic value (Ref. 55756). It is preyed upon by kingfishers and mergansers.
