Marine life of the sea trout

摘要: An understanding of when and where sea trout Salmo trutta L. are located at is essential to the effective management local populations in evaluating their vulnerability salmon lice other anthropogenic threats. Here we review available literature on life-history strategies, behaviour habitat use marine environment, including feeding, growth, survival homing. There considerable variation strategies among individuals timing duration migration(s). Females tend adopt anadromous strategy more than do males. Smolts typically leave rivers spring (March–June European rivers), but also times year. Post-smolts may remain during summer return freshwater over-winter; adults thereafter spend summers winters freshwater, or they can until later for spawning. Sea frequently recorded winter tolerate full-salinity water temperatures as low 1–2 °C. often within 80 km river origin, undertake longer-distance migrations (>500 km). The migration both likely governed by trade-offs between mortality risk growth potential different habitats, most beneficial vary populations. Reduced increased will reduce benefit result selection against anadromy.
