[0026] Large-scale cultivation method of philippine clam white seedlings in sea area

[0027] 1) Sea area selection for white seedling cultivation

[0028] In 2012, the subtidal zone and shallow sea of ​​Tong'an Sea Area in Xiamen were selected as the sea area for cultivating the white seedlings of Philippine clams. The sea area has less wind and waves, sandy and muddy bottom, stable bottom, smooth tidal flow, seawater flow rate of 20-40cm / s, salinity of 24-26, not affected by fresh water, and less harmful organisms.

[0029] 2) Clean up the sea area

[0030] In November 2012, one month before the sand seedlings were released, train cages and crab cages were placed in the seedling sea area, one per mu, to trap fish, crabs, snails and other harmful organisms. 1-2 days before the seedlings are released, use the bottom truss trawler to drag the harmful organisms at the bottom of the sea area where the seedlings are planted.

[0031] 3) Playing of sand seedlings: At the end of ...

Abstract

The invention discloses a method for cultivating large-scale Ruditapes philippinarum white spats in a sea area, and belongs to the field of aquaculture. The method comprises the following steps of choosing a white spat cultivation sea area, cleaning a sea area, sowing sand spats, preventing from natural enemies and harvesting the spats. By adopting the above technical scheme, the yield is 2.6 to 3.2 million white spats per mu, the size is 8000 to 15000 white spats per kilometer, the survival rate of the white spat cultivation in the sea area is 26 to 30 %. The method for cultivating large-scale Ruditapes philippinarum white spats can be popularized and applied to a large-scale coastal area in our country, the Ruditapes philippinarum white spats can be industrially cultivated, so the method provides spat guarantee for development of Ruditapes philippinarum cultivation.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for large-scale cultivation of philippine clams in sea areas. Background technique [0002] Philippine clam Ruditapesphilippinarum (referred to as flower clam) belongs to the clam family and the genus Clam, and is one of the four major marine cultured shellfish in my country. It is distributed from Liaoning to Guangxi in the north along the coast of my country. Philippine clam is rich in nutrition, delicious in meat, and has become one of the most important and most promising varieties of tidal flat shellfish due to its fast production speed, short breeding cycle, strong adaptability, and stable market price. An indispensable aquatic product in the vegetable basket. [0003] In foreign countries, Japan, North Korea, the Philippines, Pakistan, India, Sri Lanka, Indonesia and other countries have caught wild Philippine clams, and Hawaii, the west coast of North America, Canada...
