Parent patinopecten yessoensis culturing and hatching method

Abstract

The invention relates to a parent patinopecten yessoensis culturing and hatching method, and belongs to the technical field of parent patinopecten yessoensis culturing and hatching methods. The parent patinopecten yessoensis culturing and hatching method is characterized by mainly comprising the following steps of: (1) selecting and conveying parent patinopecten yessoensis; (2) supplying a culturing condition of the parent patinopecten yessoensis; (3) culturing and hatching high-quality parent patinopecten yessoensis, namely (1) putting the parent patinopecten yessoensis into a pool, (2) heating, (3) feeding baits, (4) changing water and reversing the pool, (5) inflating, (6) adding beneficial bacteria, and (7) performing oviposition and hatching. According to the parent patinopecten yessoensis culturing and hatching method, the technology is scientific and reasonable; the flow operation is simple and standard; the oviposition amount of the parent patinopecten yessoensis is large; and the survival rate of young eggs is high.

Description

technical field [0001] The invention relates to methods for cultivating and hatching parent-child scallops and belongs to the technical field of parent-child cultivation and hatching methods for scallops. Background technique [0002] Ezo scallop is a filter-feeding bivalve mollusk with a fan-shaped shell and is a cold-water shellfish. Ezo scallop is native to Japan, the southern waters of the Russian Kuril Islands, Hokkaido, Japan, and northern Honshu. The suitable temperature range for growth is 5-23°C, 15 The most suitable growth temperature is about ℃, and the growth is slow when the temperature is lower than 5℃. When the water temperature rises to 23℃, the living ability will gradually weaken. The suitable range for salinity is 24-40‰. It is distributed in areas with high salinity and no fresh water injection. Coastal sea areas with hard bottom, less silt and water depth not exceeding 40m. [0003] Ezo scallops are delicious and rich in unsaturated fatty acids EPA and ...

AI Technical Summary

Problems solved by technology

At present, sea areas such as Liaodong Peninsula and Changdao in Shandong are cultivated in northern my country, and their growth rate is relatively slow. From the beginning of spat to shell height of 1l-12cm, the shortest time is 1 year and 7 months, and the breeding season in northern my country is 3-3. In April, the spawning water temperature is 3-10°C. Generally, 3-4 ring shells with a shell length of 8-13cm can be used as broods. Excellent broods are the basis for cultivating robust seedlings. Therefore, select and cultivate high-quality shellfish during breeding. The spawning and hatching conditions of broccoli and broccoli are particularly important. At present, there is still a lack of systematic and excellent methods for cultivating and hatching broccoli of Ezo scallop.
