History of the pacific capelin Mallotus catervarius (osmeriformes) fishery near the sakhalin coast and reasons of its catch records in present period

Far East capelin is characterized by long-term cycles of its biomass dynamics. During XX and early XXІ century fishery of Far East capelin near Sakhalin Island was more intensive in the years of high abundance. In 1930s annual catches of this fish was not more than 0,8– 0,9 thousand tons. In 1970s catches varied from 0,93 to 2,50 thousand tons. In 2016–2022 capelin catches attained to record level, 3,5–13,7 thousand tons. Grate catches connected by complex reasons such as large spawning biomass, intensive fishery and its season near Sakhalin coast and some others. It is already clear that the northwestern coast of Sakhalin is the most ideal for reproduction, growth, and survival of capelin in the waters around Sakhalin Island. Reproduction productivity of this fish species in the Sakhalin area of Okhotsk Sea is much lower as an annual catches.
