Abstract

The invention discloses a kind of cultural method for improving Changchun bream survival rate, comprise the following steps：Fish pond is built, bottom of pond is handled, pool water treatment, fry processing, feeding management, water quality management, disease prevention and cure.Pass through the cultural method of the present invention so that the survival rate of Changchun bream improves the performance of enterprises to 89 95%.

Description

A kind of cultural method for improving Changchun bream survival rate
Technical field
The present invention relates to the technical field of fish culture, more particularly to a kind of cultural method for improving Changchun bream survival rate.
Background technology
Changchun bream, alias bream flower, long is somewhat like blunt snout bream, and is not blunt snout bream, and side is flat, assumes diamond in shape, and abdomen rib is obvious, From pectoral fin until anus dorsal fin thorn is sturdy and smooth.The high-quality fish that Changchun bream is nutritive value, economic value is all higher, its meat Matter is delicious, and muscle protein, fat content are respectively 19.38% and 2.89%.18 kinds of amino acid are detected in the bream muscle of Changchun, Which includes 8 kinds of essential amino acids.Total amino acid content is 77.60% in the bream muscle of Changchun, wherein, 8 kinds are needed by human Amino acid content is 31.70%, accounts for the 40.85% of total amino acid content.The composition of essential amino acid substantially conforms to FAO/WHO Standard.
Wild Changchun bream can be cultivated ripe under the conditions of pond culture and be used for artificial propagation, and researcher first uses LHRH-A3 accelerates the ripening, and is hastened parturition again with DOM+LHRH-A2+HCG mixing after 14-15h, then cultivates into Changchun bream seedling, but Changchun bream Because harmful organisms and subalimentation frequently result in, survival rate is not high in pond-inputting for fry, simultaneously because the resistance of fry is not Height, cause the resistance against diseases of the Changchun bream in breeding process not strong, influence the final survival rate of Changchun bream.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of cultivation side for improving Changchun bream survival rate Method, pass through the cultural method of the present invention so that the survival rate of Changchun bream to 89-95%, improve the performance of enterprises.
