A kind of breeding method of soft-shelled soft-shelled turtle

Abstract

The invention discloses a method for selecting and breeding soft-shelled soft-shelled turtles. SNP single nucleotide polymorphism analysis is used to determine Chinese soft-shelled soft-shelled turtle seedlings with excellent properties. Conduct non-specific viral pathogen detection on Chinese soft-shelled turtle seedlings, and screen out Chinese soft-shelled soft-shelled turtle seedlings without specific viruses; disinfect the breeding ponds to make them meet the breeding requirements; prepare multi-bacteria-sensitive bacteriophage microecological preparations; During the breeding process, the multi-bacteria-sensitive bacteriophage microecological preparations are regularly sprinkled; the water quality of the aquaculture water is regularly tested to determine the water quality, and the frequency of sprinkling the multi-bacteria-sensitive bacteriophage microecological preparations is adjusted as needed. The breeding method of the invention is highly operable, universal and economical.

Description

technical field [0001] The invention relates to a method for breeding aquatic products, in particular to a method for selecting soft-shelled soft-shelled turtles. Background technique [0002] Chinese soft-shelled turtle is a common aquatic product in life, widely distributed in China, Japan, northern Vietnam, and South Korea, and is rich in nutrition. With the improvement of people's living standards, the output of wild soft-shelled soft-shelled turtles can no longer meet daily needs, so more and more Chinese soft-shelled turtles come from major breeding companies. [0003] In order to increase the scale of breeding, many breeding companies adopt greenhouse and intensive farming. The breeding density is very high, and bacteria often breed during the breeding process, which reduces the yield of Chinese soft-shelled turtles. Personnel have developed various disinfectants, such as 0.3-0.5ppm povidone-iodine or 1ppm glutaraldehyde for full pond spraying. The disinfection effec...

Problems solved by technology

[0007] In the breeding process of soft-shelled soft-shelled turtles, the previous selection method was mostly to select seedlings with excellent traits from generation to generation. Sometimes it took a lot of time to breed stable and excellent strains. The selection standards were mostly observed with the naked eye, and the standards were not uniform. Most of the technicians think that it is enough to be big and healthy

[0008] None of the above problems has actually solved the actual problems in soft-shelled soft-shelled turtle breeding, and there is an urgent need for an effective way to overcome the problems in the prior art
