Data on the species composition of the fish population inhabiting the tributaries of the Novosibirsk reservoir are given in the article. The structure of fish communities and possible environmental factors determining it have been revealed. The relation between the heterogeneity of fish communities and the river depth and length, relief, current velocity, floodplain, and estuarial areas, presence of sand-pebble shallow waters and channel order, has been studied.
