Cross-sea-area low carbon normal temperature spat culturing method applicable to bay scallops

Abstract

The invention relates to a cross-sea-area low carbon spat culturing method applicable to bay scallops, in particular to a cross-sea-area normal temperature spat culturing method of the bay scallops. Naturally mature autumn bay scallop individuals that are cultured in sea areas in northern China are used as parent scallops, normal temperature spat culturing is performed by natural sea water in sea areas in south of Fujian province in south China in October and November, and the scallops are intermediately cultured to pass the winter in local sea areas and transported to the sea areas in northern China to grow up in April next year. According to the cross-sea-area low carbon normal temperature spat culturing method applicable to the bay scallops, the cross-sea-area low carbon spat culturing method of the bay scallops is scientific and effective, on basis of greatly reducing spat culturing costs of the bay scallops, the effective growth time of the bay scallops can be increased, emission of carbon dioxide and dusts can be effectively reduced, environmental protection can be achieved, and sound development of bay scallop culture industry can be facilitated.

Description

technical field [0001] The invention relates to a method for low-carbon seedling cultivation of bay scallops, in particular to a low-carbon and normal-temperature seedling cultivation method suitable for bay scallops across sea areas. technical background [0002] Gulf scallops belong to Phalabranchia, Heterocylinda, Scallopidae, and Scallop genus. They are native to the Atlantic coast of the United States and are an important local harvested bivalve economic mollusk. The shell is fan-shaped, the two shells are almost equal, and the shell surface is dark brown or brown. Most of the bay scallops are distributed at 3-10 meters below the sea surface. They have a more aggressive personality and a temperature range of -1-31°C. They stop growing below 5°C, grow slowly below 10°C, and grow faster at 18-28°C. Its salt-tolerant range is 16‰-43‰, and its salt-suitable range is 21‰-35‰. Bay scallops are filter feeders, they have the ability to select the size of food, but they have n...

Problems solved by technology

The high-energy consumption and high-pollution production mode that mainly uses coal boilers to heat seawater for off-season seedling cultivation has become increasingly unable to adapt to the trend of today's social development, which also seriously affects the healthy development of the entire bay scallop industry.
