Problems solved by technology

In addition, due to the limitation of the breeding season, the relevant research on the attachment and metamorphosis of the thick-shelled mussels and the breeding time of the thick-shelled mussels that can be carried out every year are greatly reduced, and it is difficult to guarantee
For example, the patent application CN200710156048.1 discloses the artificial seedling raising method of the thick-shelled mussel, but does not disclose the method for the accelerated ripening and induced production of the thick-shelled mussel

Embodiment

[0022] The artificial ripening and spawning method of thick-shelled mussels comprises the following steps:

[0023] (1) Screen the broodstock of thick-shelled mussels after collection, select adult shellfish with regular shapes and consistent specifications, and filter seawater through a mixed fiber membrane with a salinity of 30‰;

[0024] (2) After removing the body surface attachments and cutting off the silk, the collected parent shellfish is washed with seawater and placed in a water tank filled with seawater at 13°C, and then put the water tank into an incubator for intensive cultivation ;

[0025] The period of intensive cultivation is 3-7 days, the brood density is 6 / L, all the seawater is replaced every day, the bait is Chaetoceros tenacilis or Chlorella, and it is fed 3 times a day, and the feeding density is 200×10 4 cells / ml;

[0026] (3) During the artificial ripening cultivation period, the temperature is increased by 0.5°C to 21°C every day. The seawater used...

Abstract

The invention provides a method for artificial ripening and induced production of marine mollusc mussels, which comprises the following steps: intensive cultivation of shellfish, artificial ripening, artificial induced production and final mixed hatching cultivation. The method for artificial ripening cultivation and accelerated production of mussels of the present invention is of great significance for the development of seedling production, sustainable cultivation and the like of economic shellfish such as mussels.

Description

technical field [0001] The invention relates to the artificial culture of shellfish in the field of aquaculture, in particular to a method for artificially accelerating the ripening and breeding of thick-shelled mussels. Background technique [0002] Thick-shelled mussels are important maricultured shellfish in my country. They are distributed along the coasts of the Yellow Sea, Bohai Sea and the East China Sea. Among them, the coastal resources of Zhejiang are the largest, and Shengsi County, Zhoushan is the main production area of ​​thick-shelled mussels. For a long time, the supply of seedlings required for cultured mussels has been dependent on semi-artificial harvesting in sea areas. In recent years, due to artificial over-harvesting, the natural resources of mussels have gradually decreased: the quantity and quality of seedlings in natural sea areas have declined significantly, and the aquaculture industry of mussels has been affected. In addition, due to the limitati...
