Abstract
Pink salmon spawners in the channel connecting Lake Sopochnoe (Iturup Island) with the sea are investigated. The samples were collected in July-August, 2016. The males dominated significantly during entire spawning run. The fish became more and more ready for spawning with approaching to the end of the run. The average length and weight of females were 50.0 ± 0.3 cm and 1.53 ± 0.03 kg, the average length and weight of males — 50.2 ± 0.2 cm and 1.56 ± 0.02 kg; the fish caught in the channel were significantly larger than the pink salmon spawners caught in the adjacent Prostor Bay at the same time (on average 48.5 ± 0.1 cm, 1.32 ± 0.01 kg and 49.0 ± 0.2 cm, 1.40 ± 0.02 kg for females and males, respectively).
