Chum salmon (lat. Oncorhynchus keta) is a red fish of the salmon family, known for excellent gustatory qualities. It lives in the Arctic and Pacific oceans. In Russia, fishing takes place in Sakhalin, Kamchatka, Kuril Islands.
The fish is covered with small silvery scales. The length is 70-100 cm; the weight is 4-13 kg. The meat is pink. It lives approximately 7 years, eats crustaceans, molluscs, small fish.
Like many salmons it spawns in freshwater, so it overcomes vast distances: females choose pebble bottom and spawn in several places at the same time. Then they then die from exhaustion. Males take care of the future offspring and eventually also die. Spawning occurs from late August till October (in large lots twice). The caviar is as valuable as the fillet.
Chum salmon contains vitamins, minerals, fat and polynonsaturated acids, which struggle with ageing, strengthen nails, hair, teeth, bones. This fish is useful for the cardio-vascular system; it is a natural antioxidant, strengthening the immune system.
