[0047] Please refer to figure 1 ,in, figure 1 It is a functional block diagram of the first embodiment of the method for breeding oysters that can improve the meat yield provided by the present invention. The breeding method of the long oyster that can improve meat yield, comprises the following steps:

[0048] S1: Parent selection: select the long oyster whose left shell color is golden yellow from the wild population of long oyster as the basic population, and take the golden shell color and growth speed as the breeding targets;

[0049] S2: Secondary selection: Among the offspring bred by the broodstock population selected in S1, select long oysters whose left shell color is golden and have a high meat yield, and the number is 30-35 for each male and female;

[0050] S3: group mating, the male and female long oysters selected in S2 are mated with each other;

[0051] S4: The second breeding: the oysters whose shell color is golden yellow and whose growth speed is fast in...

Abstract

The invention provides a crassostrea gigas breeding method capable of increasing meat percentage, which comprises the following steps: S1, selection of parent crassostrea gigas: screening crassostrea gigas with golden yellow left shell color from a crassostrea gigas wild population as a basic population, and taking the golden yellow shell color and growth speed as breeding targets; S2, secondary optimization: reselecting 30-35 male and female crassostrea gigas with golden left shell and high meat percentage from offspring propagated by the parentcrassostrea gigas population selected in the S2, and selecting 30-35 male and female crassostrea gigas with golden left shell and high meat percentage from the offspring propagated by the parent crassostrea gigas population selected in the S2; S3, porpulation mating: performing mutual mating on the male and female crassostrea gigas selected in the S1; and S4, second breeding: performing male and female single-pair single mating propagation on the crassostrea gigas with offspring whaving golden yellow shell color and high growth speedin the S2. According to the crassostrea gigas breeding method capable of increasing meat percentage, the crassostrea gigas is formed through continuous breeding of at least four generations by adopting a mixed breeding technology combining family breeding and group breeding, and in the same breeding environment, compared with unbred crassostrea gigas, the average shell height, the average weight and the meat percentage of 15-month-old crassostrea gigas are improved respectively.

Description

technical field [0001] The invention relates to the field of breeding methods of long oysters, in particular to a breeding method of long oysters which can improve the meat yield. Background technique [0002] Oysters, commonly known as sea oysters, oysters, etc., belong to the mollusk phylum, bivalves, and pearl oysters. They are the largest cultured shellfish in the world and one of the important marine biological resources available to humans. They are globally distributed species. Oysters are not only delicious and nutritious, but also have unique health care functions and medicinal value. They are a seafood treasure with high nutritional value. The zinc content of oysters ranks first in human food. It is believed that oysters have the functions of curing weakness, detoxifying erysipelas, lowering blood pressure, nourishing yin and strengthening yang. [0003] Among them, in order to increase the meat yield of oysters, the mixed breeding techniques such as family selec...
