Аннотация
Patterns of downstream migration of juvenile pink salmon Oncorhynchus gorbuscha in the Malaya Khusi River (northeast of Sakhalin island) are revealed as a result of observations conducted in 2014–2017. Downstream migration starts in May when water is warmed up to 4–5°С. The bulk of fish migrates seaward at 5–10°С. The duration of downstream migration is ~2.5 months. Downstream migration is confined to nocturnal period. Downstream migrants are distributed predominantly in the meadstream, at the line of fastest flow. Some species-specific mechanisms of downstream migration are made clear. The total number of pink salmon downstream migrants during the period of observations is calculated.
