Comparative analysis of the species composition of ichthyofauna of fish watering holes and adjacent channel areas of the Krasnoyarsk fl oodplain of the Volgograd reservoir

The Volgograd reservoir is a highly complex hydrological system. The locations of fi sh watering holes, which are situated in an abyssal area of the Volgograd reservoir, have been well established for a long time. Meanwhile, fi sh watering holes exist in areas of the bed of the Volgograd reservoir as well. However, their determination is not always possible and is complicated due to the small size and shallow depth of the watering holes.
