Problems solved by technology

[0003] Wild Changchun bream can be cultivated to maturity under pond culture conditions and used for artificial reproduction. The researchers first used LHRH-A3 to induce ripening, and then used DOM+LHRH-A2+HCG to induce spawning after 14-15 hours, and then cultivated Changchun bream fry. However, the survival rate of Changchun bream fry is often low due to harmful organisms and insufficient nutrition when they are in the pond. At the same time, due to the low resistance of the fry, the disease resistance of Changchun bream is not strong during the breeding process, which affects the final survival of Changchun bream Rate

Abstract

The invention discloses a culture method capable of increasing survival rate of Parabramis pekinensis. The culture method includes the steps of fishpond building, treatment of fishpond bottom, treatment of water in the fishpond, treatment of fry, feeding management, water quality management and disease prevention and control. By application of the culture method, the survival rate of Parabramis pekinensis reaches 89-95%, and accordingly enterprise benefit is increased.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to a breeding method for improving the survival rate of Changchun bream. Background technique [0002] Changchun bream, also known as bream flower, looks a bit like Wuchang fish, but it is not Wuchang fish. Its body is flat and diamond-shaped, with obvious ventral ribs. The spines from the pectoral fin to the dorsal fin of the anus are thick and smooth. Changchun bream is a high-quality fish with high nutritional value and economic value. Its meat is delicious, and its muscle protein and fat contents are 19.38% and 2.89% respectively. Eighteen kinds of amino acids were detected in Changchun bream muscle, including eight kinds of essential amino acids for human body. The total amount of amino acids in Changchun bream muscle is 77.60%, among which, the content of 8 kinds of essential amino acids is 31.70%, accounting for 40.85% of the total amino acids. The proportion of essen...
