The results of the forty-year study of the benthos fauna in water streams of the northern coast of the Sea of Okhotsk are summarized. Data on the benthos in 120 water streams are presented. The information on the bottom invertebrates diversity, on the taxonomic structure of mayflies, stoneflies, and caddisflies as well as on the density and the biomass of organisms and their communities is given. Peculiarities of the macrozoobenthos in eight length categories of water streams are considered. It is the first time for the area studied that the data on biotic indices for bottom communities in 69 water streams are published. Basins and dimensional classes of water streams most favorable for the fresh water biota development are distinguished for the area researched. One of the basic problems in hydrobiological research, censuring water organisms, is discussed basing on the example of bottom invertebrates, fish, and water plants.
The data presented can be used as background for region to the evaluation of the fish forage basis, the calculation of losses, and the assessment of the water biota state in the disturbed areas of the region.
