Passing species. Occurs in Primorye rivers and coastal seawaters along the entire coastline, but preferentially in northern areas. Its range includes the basins of Japan and Okhotsk Seas, and the western part of Bering Sea. Quite a large fish, attaining in Primorye 99 cm in length and 11 kg in weight. Lives for up to nine years. Specimens of different size and age occur in catches, most frequently 32-76 cm long, weighing from 0.3 to 5.7 kg at the age of two to four. Attains sexual maturity in the third-fourth year of life when 23-40 cm long. Enters Primorye to spawn in late June-early August. Spawns in September. Spawns similarly to Pacific salmon to bury its roe. In addition to passing males, spawning also involves dwarf males. After spawning, the fish stay in the river till spring to then roll into the sea. When it fattens in the sea, the char does not perform lengthy migrations to keep close to near-estuary river sites or not far from the coast. In summer, it actively feeds on smelt, sand eels, gobies and Pacific salmon young when they roll into the sea. In some cases, in accumulating near spawning river estuaries, the char would eat a considerable amount of rolling keta and gorbuscha young. The char would return to rivers to hibernate. The young would spend from two to four years in the river to subsequently start rolling into the sea to fatten in summer. While they stay in the river, the young would feed on the larvae of caddis flies and other insects. The char is a valuable food species and the object of local fishery and amateur fishing.
