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.

Pastoral aquaculture in the reservoirs of the Kuban basin

“…The ichthyofauna of the Krasnodar reservoir formed at the expense of fishes that lived before in Texcom reservoir, fish the middle and lower reaches of the river Kuban and its left-Bank tributaries: the rivers Laba, Belaya, Pshish, Psekups, etc. Various sources note the great diversity of the fish fauna of the basin of the Kuban river, with more than 79 species and subspecies of fish, of which 36 are constantly encountered in the reservoir, and 43 species and subspecies occur sporadically at different times of the year [5,6,7]. They include marine, pass-through and semi-passable fish (Beluga (Huso huso), sevruga (Acipenser stellatus), russian sturgeon (Acipenser gueldenstaedti), black sea shad (Alosa maeotica), black sea sprat (sprat) (Clupeonella cultriventris), three-legged stickleback (Gasterosteus aculeatus), and Common percarina (Percarina demidoffi), donets ruffe (Gymnocephalus acerinus), European anchovy (Engraulis encrasicholus) and some types of gobies), which found favorable conditions for reproduction both in the reservoir bowl and in the rivers that flow into it, as well as some universes -sturgeon (Acipenser ruthenus), american paddlefish (Polyodon spathula), smallmouth buffalo (Ictiobus bubalus), grass carp (Ctenopharyngodon idella), black carp (Mylopharyngodon piceus), channel catfish (Ictalurus punctatus), silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis).…”

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 share of cultivation of various tilapia species and hybrids in global aquaculture is steadily increasing every year, which is explained by their unpretentiousness, valuable dietary indicators, as well as relative availability, due to the low cost of the products obtained. A wide range of tilapia nutrition (suspended particles, fouling, planktonic organisms) allows them to be used as biological reclamation agents, allowing additional commercial products to be obtained without costs and environmental factors to be normalized [3,4].…”
