Breeding method of cultivating hybridized scallops of purple scallops and bay scallops in south and raising hybridized scallops in north

Abstract

The invention belongs a breeding technology of shellfishes and particularly relates to a breeding method of cultivating hybridized scallops of purple scallops and bay scallops in the south and raisingthe hybridized scallops in the north in order to achieve large-scale cultivation of the scallops. According to the breeding method, the young hybridized scallops of the purple scallops and bay scallops are cultivated in the south during autumn and then transported to northern sea areas for follow-up raising in next spring. A new hybridized species selected from the first generation of the hybridized scallops of the purple scallops and bay scallops for breeding is adopted as the breeding scallops, the young scallops are cultivated in the south during autumn and then transported to the northernsea areas for follow-up raising, and therefore the commercial scallops with large specification are cultivated. Through establishment of a breeding pattern, the breeding time of the hybridized scallops of the purple scallops and bay scallops is prolonged, the breeding range is expanded, the specification of the bred scallops can be effectively increased, the value of scallop products is higher, and the quality and safety of the scallop products are effectively ensured. The yield of high-quality marine protein is increased, the income of fishermen is increased, and a new way to healthy sustainable development of the scallop breeding industry is created.

Description

technical field [0001] The present invention belongs to the breeding technology of shellfish, and in particular relates to a cultivation method of “Southern cultivation and northern cultivation” of purple sea hybrid scallops raised in the south in autumn, and then moved to the northern sea area for further cultivation in the spring of the following year to cultivate large-sized scallops . Background technique [0002] Scallop is the main cultured species in my country's aquaculture industry, and occupies a pivotal position in my country's mariculture. The scallops cultured 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 bay scallop itself has a small commercial size and a short lifespan. Long-term sterility will lead to germplasm degradation and high mortality. The commercial shell size is getting smaller and smaller, which ca...
