On the territory of the lower reaches of the Tumannaya River (LRT), a significant number of fresh and brackish-fresh reservoirs are concentrated, some of which open into the Sea of Japan. Historically preserved network of channels and watercourses, which connects these bodies of water in the system, creating conditions for a wide exchange of fish fauna between the bodies of water. This system works especially effectively during flood floods, but this side of the dynamics remains poorly understood. Natural conditions have been preserved in the LRT to support the existing fish fauna dynamics. The oriented protection, competent creation of fish-breeding and fishing farms could improve this dynamics and at the same time promote rise of economy of the area.
