Abstract

This study deals with the distribution of pink salmon spawners, which were tagged during embryogenesis at the Anivsky salmon farm, in the water area of the Sakhalin region. A majority of the tagged salmon were caught in the Bystraya River near the salmon farm. As well, the pink salmon spawners with the fish farm tag in the otoliths were found all over the water area of southern Sakhalin and Iturup Island. Here, the number of farm-reared salmon that were caught in the common migration routes or settled in the different water courses exceeded the number of fish that returned to the basic river of the Anivsky salmon farm by several times.
