Current state and prospects for development of autumn chum salmon aquaculture in the Amur River basin

The paper presents data proving the importance of factory farming of autumn chum salmon in the formation of its commercial stocks in the Amur River basin. It has been established that an increase in the release of chum salmon juveniles by 1 million specimens gives an average increase in the catch after 3 years of 0,18 thousand tons. A set of measures aimed at developing the resource base of autumn chum salmon is proposed. In the Amur basin, it is proposed to increase the release volumes of autumn chum salmon juveniles from state hatcheries and to create a network of private hatcheries. The total release volume of juveniles is supposed to be set at 200 million specimens of autumn chum salmon juveniles per year, which can potentially bring an additional approximately 13,6 thousand tons of autumn chum salmon return. To achieve this indicator, it is necessary to build 10–15 hatcheries. It is proposed to allocate 3 areas with specific features of fish farming activities: small rivers of the Amur estuary; the lower reaches of the river. Amur from Komsomolsk-on-Amur to Nikolaevsk-on-Amur and the mouth of the Amur River from Nikolaevsk-on-Amur to the mouth of the Amur.
