Problems solved by technology

Artificial heating factory seedling cultivation: Although the seedling cultivation process is easy to control, it is necessary to build a water supply and heating system to meet the cultivation conditions such as water temperature, which consumes a lot of energy and costs, and the labor intensity of the workers is very high, and coal-fired boilers are harmful to the atmosphere and The water environment has been severely polluted again, destroying the coastal environment; after continuous exploration, natural seedling harvesting in sea areas has made good progress in recent years: compared with artificial heating and industrial seedling raising, artificial natural seedling harvesting has less investment and higher output, but The yield of seedlings is unstable, greatly affected by environmental changes, the area for seedling collection is limited, and the size of seedlings is small

Embodiment 1

[0013] Healthy breeding method of scallop seedlings, Liaoning and Shandong coastal shellfish ripening → oviposition and fertilization → fertilized egg hatching → D-shaped larvae screening → packaging southward transportation → larvae cultivation along the coast of Fujian and Guangdong → sea spat cultivation → return to Liaoning Breeding with the coast of Shandong. Specific steps are as follows:

[0014] (1) Seed shellfish to promote ripening, fertilization and hatching

[0015] In late December, broilers were selected in Liaoning and Shandong for indoor maturation. In late January of the second year, the gonads of broilers matured indoors were matured, and eggs were fertilized by artificial induction. The fertilized eggs hatched The D-shaped larvae do not eat bait, and the D-shaped larvae with strong activity and no deformity are screened out.

[0016] (2) Southward migration of D-shaped larvae

[0017] The transportation time depends on the spawning time of the broodstock ...

Abstract

The invention relates to the technical field of aquaculture, and relates to a technology for cultivating sea scallop seedlings, in particular to a new method for healthy cultivation of scallop seedlings. The healthy breeding method of scallop seedlings uses the temperature difference between the north and the south to promote the maturation of scallop seed shells in the north, so that they can lay eggs, fertilize and hatch fertilized eggs. After the fertilized eggs hatch into D-shaped larvae, the selected healthy The D-shaped larvae are transported to the south for overwintering larvae cultivation, and are cultivated to spat with an average shell height of 0.3-0.5 cm, and then the spat that have survived the winter are returned to the northern breeding sea area for cultivation. The invention makes full use of the natural temperature difference between the north and the south in winter to cultivate scallop seedlings, with less economic investment, high and stable seed production, energy saving, emission reduction, low-carbon and environmental protection, and meets the requirements of ecological breeding. The shrimps cultivated in this way Scallop seedlings grow fast and have a high survival rate in summer, and the breeding period of adult shellfish is shortened by about 2 months. It is of great significance to the upgrading of Ezo scallop industry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and relates to a technology for cultivating sea scallop seedlings, in particular to a new method for healthy cultivation of scallop seedlings. Background technique [0002] Ezo scallops are large cold-water shellfish native to Japan, the southern waters of the Kuril Islands in Russia, Hokkaido in Japan and northern Honshu. At present, Ezo scallop has become one of the main marine cultured shellfish in northern my country. It is mainly cultivated in sea areas such as the Liaodong Peninsula in northern my country and Changdao in Shandong. [0003] In the north of my country, the cultivation of scallop seedlings is currently divided into two methods: artificially warming industrial seedlings and natural seedlings in sea areas. Artificial heating factory seedling cultivation: Although the seedling cultivation process is easy to control, it is necessary to build a water supply and heating system...
