Pastoral aquaculture in the reservoirs of the Kuban basin

Abstract

The article provides calculations and recommendations for fisheries development and improvement of fish productivity of reservoirs in the Kuban basin. The taxonomic composition of water biological resources has been studied and the natural bio-production potential of some reservoirs in the South of Russia has been determined. It is proposed for the purpose of pastoral aquaculture to produce directed formation of the ichthyofauna of reservoirs by yearlings Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Ctenopharyngodon idella, and as anaddition Cyprinus carpio, Mylopharyngodon piceus, Liza haematocheila with an individual mass not less than 25-30 g, which will allow rational use of forage resources of aquatic ecosystems.

Fish farming on riverbed ponds of the Azov-Kuban plain

“…Studies have shown that the phytoplankton of riverbed ponds located on the rivers of the Azov-Kuban plain is represented by 125 taxa of algae belonging to 9 groups: Chlorophyta -37 taxa, of which Protococcophyceae -28, Volvocophyceae -6, Desmidiales -3, Bacillariophyta -33 taxa, Euglenophyta -16, Cyanophyta -26, Pyrrophyta -8, chrysophyta -3 and Xanthophyta -2 taxa. The results obtained are comparable to previous studies within the Azov-Kuban plain [8] Zooplankton is represented by three typically planktonic groups of organisms: Rotatoria, Copepoda, and Cladocera [9,10]. The zooplankton species analysis identified invertebrates belonging to 24 taxa: Rotatoria-16, Copepoda-4, Cladocera -4.…”

Current state of the fishing industry in the Krasnodar region and its contribution to the country's food security

“…The rivers of the Azov-Kuban plain Yeya, Chelbas, Beysug, Kirpili, Ponura, Albashi, Yaseni and their tributaries are regulated and represent a cascade of reservoirs (ponds-reservoirs) with an area of 5-10 to 300-500 hectares or more. According to Kubangiprovodkhoz, there are about 1300 reservoirs on the rivers of the Azov-Kuban plain, with a total area of about 50 thousand hectares [11,12].…”

Joint cultivation of sturgeon and tilapia in cages on small rivers (Krasnodar territory)

“…The fertility of large females can exceed 100 thousand eggs, fluctuations of 4-140 thousand. The diameter of the oocytes is 2-3 mm, the weight is 8-9 mg. Development varies from 4 to 9 days depending on the water temperature [9].…”

“…It is able to reproduce regularly with an interval of 25-80 days. [9]. Channel ponds located on the rivers of the Azov-Kuban plain (Yeya, Kirpili, Chelbas, Beysug, Kalaly and their tributaries) can be used to expand the cultivation of sturgeon species of fish (sterlet) in the Krasnodar Territory.…”
