Dog Salmon, Chum Salmon

Dog SalmonDog salmon is the second most numerous Pacific salmon species after pink salmon. It can be distinguished from pink salmon, king salmon, sima and silver salmon by the absence of spots on the back and caudal fin. Moreover, the fish which has just entered the river shows some features of mating dress – pinky or grey crosswise stripes. The specific features of its mating dress include bright crosswise red and green stripes with inclusions of black color. В Males develop big teeth preventing the mouth from closing. Its length is up to 102 cm, weight – up to 14-15 kg. Western Kamchatka rivers become home for specimens 52-78 cm long weighing 1.7-5.4 kg.

Dog SalmonDog salmon exists in two forms – summer and autumn. The autumn one is bigger in size, weight and superior in productivity; it also grows faster. It enters Kamchatka rivers in July-October at the age of 3-10 years; specimens of 4, 5, 6-years old take part in spawning. Reproduction period is August-October.
Dog salmons run for spawning up river heads and feeders to their spawning places located farer then those of pink salmon: on river reaches with fine pebble ground and in places of ground waters outflow. The roe is laid in 2 or 3 redds. Hatching occurs in 70-100 days after fertilization, the yolk sac degrades in 90 days, after which the fish begins moving down the river. In small rivers, migration ends in May, in long rivers, it may last throughout the summer. During the first and sometimes the second year after the migration, the young fish live in coastal waters in bays and gulfs. Then they feed and hibernate in the ocean, very far from estuaries of spawning rivers. During this period, dog salmon disseminates in the northern part of the Pacific Ocean and partially in the Bering Sea.
