Zoobenthos in the streams of Khasyn river basin (seacoast of Taui Bay, Sea of Okhotsk)

On the basis of original study new data on zoobenthos of streams on the coast of Taui Bay were obtained. Composition, number parameters and structure of communities in the upper reaches of the Khasyn river and its tributaries were revealed in native conditions. For the first time seasonal and year-to-year dynamics of density and biomass of bottom invertebrates in the coastal streams were represented. New data for the streams of the Khasyn river basin on 18 species, 10 genera and 6 families of amphibiotic insects are given. By the present day their list includes 21 species of mayflies, 13 stoneflies, 12 caddisflies and 8 families of diptera.
