Embodiment 1

[0030]At the beginning of May 2012, the new strain of scallop "Bohai Red", which was nearly mature in gonads, was brought into the nursery room, and the gonads matured after a week of maturation using the conventional bay scallop seedling maturation method. Stimulate scallop oviposition with dry dew plus temperature stimulation, cultivate larvae according to the conventional culture method of bay scallop larvae, put plastic attachment base when 30-50% of larvae appear eye spots, and continue to cultivate for about 15 days after larvae metamorphosis. When the shell is 0.5 mm high, put it in a 60-mesh seedling preservation bag and directly transfer it to the Laizhou sea area for seedling preservation. After 2 weeks of seedling preservation, the seedlings were separated from the mesh, and transferred to 40-mesh mesh bags at a density of 3000-4000 per bag to continue cultivating. After about 30 days of cultivation, they are transferred to 20-mesh temporary cages at a density of 1,...

Embodiment 2

[0032] The "Qingnong No. 2" scallop seed raised in Laizhou, Shandong in March 2014 was cultured in the sea area of ​​Laizhou, Shandong. When the shell height reached about 2.4 cm in early August, it was airlifted to Xiamen and then cultured in Dongshan sea area. The height reaches about 6.4 cm, and the survival rate is about 65%.

Abstract

The invention belongs to a shellfish breeding technology, and particularly relates to a 'northern breeding and southern raising' culture method in which hybrid scallops of argopecten purpuratus and argopecten irradians are bred in the north and then transferred to the south for raising to culture large-sized scallops. A new hybrid variety bred from the first-filial generation of argopecten purpuratus and argopecten irradians is used as seed scallops, scallop seedlings are bred in the north in early summer or autumn and then transported to a southern sea area to continue being cultured, and large-sized commercial scallops are obtained. The method can effectively increase the size of cultured scallops, increase the value of scallop products, effectively guarantee the product quality and safety of scallops, increase the production of high-quality marine protein and increase the income of fishermen, and provides a new path for the healthy and sustainable development of the scallop cultureindustry.

Description

technical field [0001] The invention belongs to the cultivation technology of shellfish, and in particular relates to a cultivation method of "north breeding and south cultivation" in which purple sea hybrid scallops are raised in the north and then moved to the south for cultivation to cultivate large-scale scallops. Background technique [0002] Scallop is the main aquaculture species in my country and occupies a pivotal position in mariculture. The cultured scallops in my country are dominated by the northern subspecies of the Gulf scallop in the north, and the southern subspecies of the Gulf scallop (also known as the Gulf of Mexico scallop) in the south. The commercial size of the two bay scallop subspecies is small, the life span is short, and the long-term sterility leads to the degradation of the germplasm of the species, high mortality, and the commercial shell size is getting smaller and smaller, which cannot meet the market demand for large-size scallops. In orde...
