Continuous outmigration and sequential encountering of environmental cues are important for successful homing of hatchery‐reared, anadromous brown trout <scp> <i>Salmo trutta</i> </scp>

When rehabilitating and reintroducing trout Salmo trutta in rivers, it is a goal that as many possible survive, home form self-sustaining populations. Hatchery-reared, anadromous S. have significant lower ability to return the area where they were raised if (a) transported closed tank sea released 5 km from River Imsa, relative those (b) when swimming partly submerged with water run-through, while being slowly towed by boat same distance or (c) at outlet of Imsa. Thus, deprived environmental cues during part way, lose their home.
