Fish resources of the Novosibirsk region: current state of the fishery

Abstract

There are 22 species of fish were noted, however, only 15 species included in the fishing statistics in 13 commercial units are covered by the fishery in the Novosibirsk region. The main commercial value are fishes of the genus Carassius (Carassius carassius and C. gibelio) — 27.4% of fish catches in the region, perch Perca fluviatilis — 21.0%, Common carp Cyprinus carpio — 17.7% and roach Rutilus rutilus — 12.1%. Freshwater bream Abramis brama, providing 83.4% of the volume of fish production in the Novosibirsk reservoir and 58.3% in the Ob river, makes up only 8.0% of the catches in the whole region. The main volume of fish catch in the Novosibirsk region is provided by Lake Chany. There are almost 17% more fish are caught than in other water bodies in aggregate. The total catch in the region over the past 5 years amounted to 41.8 thousand tons. At the same time, a significant increase in catches is observed over this period — more than 1.9 times, from 5.4 to 10.3 thousand tons per year. However, the potential volumes of fish production in the Novosibirsk region significantly exceed the fact catches and over the past 5 years have been determined in the amount of 57.2 thousand tons. The main reason of the fish stocks underutilization is, first of all, the existing system of fishery organization — where there are few fishers, the development of stocks is much higher. In addition, the intensity of fishing for some species is greatly influenced by the market price of its.
