As conducting major factors prudovogo economy on an intensive basis it is possible to name fertilizer of ponds, cultivation of fishes in polyculture, more dense landing and good feeding.
Maintenance of sufficient and high-grade feeding has crucial importance. As practice of cultivation of fish in rybhozah shows, as a whole it is necessary to spend for one kg of the added weight on the average about two kgs of a forage. It gives an increase at the rate on hectare to six and more centners. If at forage enough to provide in a monoculture landing density, say, five-six thousand carps on hectare efficiency can be increased to 22 ts. At cultivation in polyculture of carps and rastitelnojadnyh fishes can be lifted efficiency still above - till 40-45 ts from hectare. In separate skilled ponds it has been received almost to 100 ts fishes from hectare of the water area. However at increase of density of landing of fishes in polyculture approximately on hectare the weight of one commodity fish decreases to 11 thousand pieces for 300-350
Some experts recommend to grow up, for example, in rybhozovskih ponds with intensive development of a phytoplankton polyculture at a following quantitative parity at the rate on hectare: a carp - 1,5 thousand, a white silver carp - 2,5 thousand, a motley silver carp - 800, a white cupid - 200 pieces. For ponds in which are rather well developed a zooplankton and bentos, the following variant is optimum: a white silver carp - 1,5 thousand, channel somika - 2 thousand, a motley silver carp - 1 thousand, a white cupid-110 pieces. In ponds with a low forage reserve it is recommended to grow up in equal quantities of a carp and a white silver carp - on 2-2,5 thousand pieces on hectare.
The cited data is received on rybhozovskih ponds. Therefore in each specific case it is necessary to do the calculations, proceeding from the pond area. The main thing - to begin, and the life then will prompt optimum variants ryborazvedenija.
But we yet have not answered a question: where to take fishes for installation? If a pond small any part of fishes can be caught in natural reservoirs, the rivers, lakes, ponds, using usual fishing tackles: fishing tackles, donki etc. But it is better to get nevertheless fish young growth in the next specialised fish-breeding economy, on ryborazvodnoj stations or in a local society of hunters and fishers. For it it will be spent and less time, and means. On delivery fishes from an acquisition place to destination without a motor vehicle not to manage. Is better, if there will be a transport specially equipped for transportation of fish. But it is possible to use and any other car. For transportation the most various capacities will approach: the enameled buckets, dairy cans, polyethylene bags and other capacities. In a polyethylene bag, for example, capacity of 20 l can be transported within 2-4 hours to 100 thousand larvae, either one thousand malkov, or 20 godovikov. Thus it is necessary to remember that transportation causes "nervous" shocks in fishes. Therefore it is necessary to try to deliver them to a new habitat, without injuring. At installation in fishes can cause a shock a difference of temperature of that water in which they were during transportation, and that in which they should be let out, and also a difference in a chemical compound. That this shock has not occurred, in container, in which fishes have been delivered, gradually add water from an installed pond. This most levels temperature, and fishes gradually get used to new water. It is possible also a polyethylene bag with fishes to lower in a pond and some time to take for temperature alignment, simultaneously also adding in it water. Then fishes are issued in a reservoir.
