Fish farming on riverbed ponds of the Azov-Kuban plain

Abstract

The article presents calculations and recommendations for fisheries development and improvement of fish productivity of riverbed ponds of the Azov-Kuban plain on the example of the Kirpili river. We studied the taxonomic composition and calculated the biomass of the natural fish food base of the studied reservoirs, which includes: phytoplankton-383.5±0.24 kg/ha; zooplankton-86.8±1.14 kg/ha; zoobenthos - 28.7±1.30 kg/ha, macrophytes - from 10 to 45 kg/m2. The species composition of the Kirpili river ichthyofauna includes 11 species of fish. With the aim of pasture aquaculture stocking of channel ponds lowland rivers it is necessary to produce fingerlings Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Ctenopharyngodon idella, and as addition Cyprinus carpio, Mylopharyngodon piceus, Liza haematocheila, Polyodon spathula, etc.) individual weight below 25-30 g, which will allow you to fish more 1350,0 kg/ha.
