Problems solved by technology

Dark-colored shells are easy to absorb light energy and heat. The water temperature in the northern sea area of ​​my country is high in summer and the light is strong, so it is difficult for common Ezo scallops to spend summer; while albino individuals can adapt to the environmental conditions in my country's breeding sea areas; A report on the production of white scallops that are easy to survive summer, grow fast, and have bright shell colors by using the method of shell color selection

Embodiment Construction

[0014] Describe in detail the white shell color scallop selective breeding method of the present invention below by embodiment:

[0015] The specific operation process of the preferred embodiment comprises the following steps:

[0016] 1. From the Ezo scallops with traditional shell color, select the mutant individuals whose shell color is pure white on both sides as the broodstock for temporary breeding; 2. Select the broodstock individuals with mature gonads to induce labor; 3. Observe the sperm discharge of the broodstock The condition of the eggs, and measure and analyze the size and vitality of the sperm eggs. After the brood shells have discharged the sperm eggs, fully mix the appropriate amount of sperm and eggs to fertilize them; 4. The fertilized eggs are hatched and cultivated to obtain juvenile shellfish , observing the growth and survival of the seedlings; 5, identifying and screening the shell color of the obtained seedlings; So far, 100% of the seedlings with pu...

Abstract

The present invention relates to a breeding method of white scallop new line. Said breading method includes the following several procedures: parent scallop cultivation, promoting oviposition, spat seed breeding, shell color identification and screening and secondary shell color selection and breeding.

Description

Technical field: [0001] The invention belongs to the marine biological technology, belongs to the selective breeding and genetic improvement technology in the shellfish genetic breeding research, and is a technical method for cultivating stress-resistant, high-yield and high-yield cultured scallop strains. Background technique: [0002] Selection breeding generally refers to the use of natural variation groups of existing species and varieties to breed new varieties or new strains through selection means called selection breeding (selection breeding), referred to as selection breeding. Selective breeding can provide new varieties or strains for production. [0003] Patinopecten yessoensis is a large-scale cold-water bivalve mollusk introduced from Japan in the early 1980s to my country and gradually cultivated. It has been cultivated in a large area in northern my country. The color of the left shell (upper shell) of Ezo scallop populations is generally purple red, and the ...
