A kind of method for large-scale cultivation of philippine clam seedlings

A technology of Philippine clams and breeding methods, which is applied in the fields of climate change adaptation, fish farming, application, etc., can solve the problem that there is no industry for Philippine clam seedlings and aquaculture production, the level of breeding technology is low, and the number of seedlings cannot meet the needs of breeding. Production requirements and other issues, to achieve the effect of a good substrate environment, reduce refrigeration steps, and shorten the time for seedling cultivation

Problems solved by technology

Since then, the seedling cultivation and aquaculture production of Philippine clams have gradually developed. However, because the technical level of seedling cultivation was limited to ponds with an area of ​​tens of acres, the number of seedlings cultivated could not meet the requirements of aquaculture production, and the level of breeding technology was still low. Cub breeding and breeding production did not form an industry

Embodiment 1

[0032] 1) Sand blowing and disinfection in the reclamation area: the single mouth area of ​​the reclamation area is 10,500 mu, and the surrounding embankments are protected by strip stones. The average pool depth is 3.5m and the water depth is 3.0m; on June 3, 2012, the water was drained and the reclamation area was exposed to the sun for 28 days. Disinfect the whole pool for 1 day, then soak and rinse twice; ship fine sand to the side of the dam in the reclamation area, with a particle size of 0.2-0.5mm, blow the sand into the reclamation area by laying a special pipeline, and use a bulldozer to level the sand layer to a thickness of 10cm . Spray and disinfect the whole pond with quicklime 42kg / mu, and inflow water to 100cm after 2 days.

[0033] 2) Parental selection and induced labor: On September 4, 2012, 93% of the 1st instar clams were selected in stage III gonads (the surface of the soft body is completely covered by gonads, the gonads are plump and bulging), and the sp...

[0037] Embodiment 2 Philippine clam white seedling sea area large-scale cultivation method

[0038] 1) Sea area selection for white seedling cultivation

[0039] 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.

[0040] 2) Clean up the sea area

[0041] 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.

[0042] 3) Playing of sand seedlings: At the e...

Abstract

The invention discloses a Ruditapesphilippinarum seedling large scale cultivation method, belongs to the aquatic product cultivation field, and the method comprises the following steps: reclamation area sand blowing and disinfection, parent selection and spawning induction, planktonic larva cultivation, adhesion juvenile mollusk cultivation, and sand seedling harvesting; by using the method, 50,000,000-120,000,000 Ruditapesphilippinarum sand seedlings (shell length 1.5-4mm) can be grown in each mu; the method can be applied to coastal area in our nation, thus realizing Ruditapesphilippinarum seedling large scale and industrialization production, and providing seedling guarantee for developing Ruditapesphilippinarum cultivation industry; the method is simple in operation and easy in promotion.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a large-scale cultivation method for philippine clam seedlings. Background technique [0002] The Philippine clam Ruditapes philippinarum (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 species in tidal flat shellfish due to its fast production speed, short breeding cycle, and strong adaptability. lack of aquatic products. [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, and Australia have also introduced Philippine clams, bu...
