Marine migrating herring of the Caspian Sea

Abstract

In the Russian water area of the Caspian Sea, after a long period of prohibition of marine net fishing, there is an increase in the intensity of catching marine migratory herring. Long-term monitoring studies confirm that the three species of the most massive herring (Dolginsky herring, Caspian puzanok, Big-eyed puzanok) are characterized by the stability of the biomass of the stock, the structure of populations by age and size-weight composition, the distribution of concentrations on spawning grounds, the yield of new generations. Sea herring is one of the underutilized resources of the Caspian Sea. Possible ways of solving the problem of development of fishing reserves are considered. The current state of reserves makes it possible to increase the annual industrial withdrawal of sea herring to 15,4 thousand tons.
