GROWING OF ORGANIC FISH IS IN NATURAL POND

Abstract

The ponds of natural zones is economic activity on the most variety’s in limit, a sent to maximal of ecosystem maintenance – adherent territory to the pond and variety of flora and fauna. To organization of organic fish-farms on the ponds is natural zones creates the swift reduction to the prime price of fish is for a sale and improvement of basic fish economic indexes.
 
 Researches our methodology is envisaged the study of features are growing and productivity of fish in three types: Сarpio, Ctenopharyngodon idella, Hypophthalmichthys in the conditions of natural pond at the organic growing of fish-farming.
 Feeding of the Сarpio in a natural pond at the organic growing of fish-farming was begun, when the temperature of water attained +10˚С. For the gradual getting is a fish used to the feed, in places laid into forage out is feed small portions for 2-3 kg. The feeding was distributed once for twenty-four hours of morning oh a 6-7 o'clock, that fish of him used to 12 hour, and in the second half of day she consumed natural forage. The important index of working out of fish is a rate of height, most intensive grew and the greatest average daily increases marked for fishes in the summer months of from 4 to 15 g on a head for twenty-four hours. At the beginning of growing of the Сarpio is consumption of forage on a head for twenty-four hours, were within the limits of a 4-5 g, and maximal a 7 g, showed up in August, when increase under yearling is mainly arrived at due to feeding of forage.
 The economic indicators of growing of fishes testify at the terms of natural pond and of organic fish-farms, about the greatest profitability is the Hypophthalmichthys – the 61 percent, in a subzero the Сarpio – 42 percent and on three types of fishes – 52,67 percent. Complex intensification of growing of fish is the scientifically reasonable system of economies of resources and money, is the mortgage of efficient of the economy of organic fish-farms.
