Purpose: development of a layout-design solution for water intake from a surface water body, excluding the entry of harmful aquatic organisms into fish-breeding reservoirs. In accordance with modern ideas about water intakes that meet the requirements of fish protection and prevent the ingress of aquatic organisms into water supply system of fish-breeding complexes, filtering water intakes are the most effective.  Materials and Methods. The water intakes structures development is based on the materials of the fish and water body surveys and the results of the analysis of developments in this area.  Results. As part of water nutrition system of the fish-breeding complex, it is proposed to use a water intake with a two-chamber water inlet equipped with filtering panels and regulating screens. Filtering panels located at the head of each of the chambers ensure the retention of harmful, weed and predatory aquatic organisms, and the screens ensure the water inlet shutdown at replacing the filtering panels. Various modes of water inlet chambers operation are considered for intake of various water flows, replacement of filter cassettes and shutdown of water intake operation. It is proposed to use a filtering panel with impervious chambers, which make it possible to simplify the cleaning of its filler as a filtering element.  Conclusions. A layout solution for a filtering water intake as part of water nutrition system of the fish-breeding complex has been proposed and developed. The design of a two-chamber water intake based on the use of filter panels and impervious screens, providing fish protection functions and preventing harmful, weed and predatory species of aquatic organisms from entering the water supply system is developed. A technology for water inlet functioning under various operating modes of the water intake has been developed. It is proposed to use a filtering panel with a simplified scheme for cleaning it from colmatation products as a water inlet element of the water intake.
