Problems solved by technology

However, green clams go through a number of tedious processes from brood induction, larvae cultivation to spat out of the pond. Due to the high requirements for water quality, cumbersome process, and long cycle, the seedlings are easily affected by bait, water quality, and bottom quality. Failure of Indoor Factory Cultivation of Green Clams

Embodiment Construction

[0006] The technical scheme of the present invention selects green clams whose growth period is 2-3 years old, shell length ≥ 3.0 ≤ 4.0cm, and gonad plumpness ≥ 30%, and place the broodstock to be induced to dry in the shade for 5-6 days in a ventilated place on the back of the sun. Hours, in the evening, after cleaning the dried broccoli, soak it with 5ppm potassium permanganate for 20 minutes, then rinse it with sea water, put it into the oxytocin net cage and put it in the pool. The oxytocin density is 2kg / m 2 For broilers, put 1-2 No. 100 or No. 120 diffusers under the oxytocin net cage, and continuously inflate the water to make the pool water boil. The water for oxytocin and seedlings is dark sedimentation, sand filter, and filtered through 1000-mesh industrial wool. Water; if there is no sedimentation and sand filter equipment, you can put the water in other pools first, sprinkle the whole pool with 10-15ppm sodium hypochlorite, stop the inflation after inflating for 3-5...

Abstract

The invention is concerned with the outdoor manufactory raising seedling method for cyclina sinensis, the characteristic is: puts the spats into the pool that the water temperature is 25 centigrade to 28 centigrade, the salinity is 20 per mill to 25 per mill , the water level is 0.8cm to 1.2cm and the water is dark deposit filtration, puffs under the mesh box; processes dark processing of the pool; the incubation water temperature is 27 centigrade to 30 centigrade, the salinity is 20 per mill to 30 per mill , the light irradiation is under 500lux; moves the D larva into the pool that is same with the incubation water quality, the light irradiation is under 1000lux; the cultivating density of the larva is 10 to 15 per milliliter, feeds the single-cell alga, changes the water at each morning or evening; moves the anaphase larva into the outdoor pool that is with bottom mud, the water deep is 50 cm, the water temperature is 25 centigrade to 32 centigrade, the salinity is 5 per mill to 32 per mill , and with gas head, feeds the single-cell alga, the light irradiation is under 3000lux; changes water every day after the adhesion of the larva; cleans the bottom of the pool once two days; evacuates the spats when the density of the spats is over 100 per cm2.

Description

Technical field: [0001] The invention relates to aquaculture, in particular to a method for industrialized artificial seedling cultivation of green clams. Background technique [0002] Green clam is one of the cultured species of coastal tidal shellfish in my country. Domestic scholars have successively carried out research on the morphological structure, reproductive biology, and living habits of green clams, and tried indoor factory breeding. However, green clams go through a number of cumbersome processes from brood induction, larvae cultivation to spat out of the pond. Due to the high water quality requirements, cumbersome process, and long cycle of seedling breeding, they are easily affected by bait, water quality, and bottom quality. The failure of indoor factory breeding of green clams. Therefore, need to have a practicable method, be used to solve the problem of the failure of green clam factory nursery. Contents of the invention [0003] The problem to be solve...
