In recent years, Wenyu pond culture has developed rapidly. Due to the water quality and residual baits in shrimp ponds, which are affected by changes in climate, tides, and sea conditions, the ecological environment in which Wenxi grows is superior. Therefore, its growth rate is much faster than that of beach culture. With high efficiency and good results, it has already come from behind. 1. Preparation for stocking before stocking Before the stocking, the pond should be completely sterilized and sterilized. The quicklime (100kg/mu) and the tea cake (100kg/mu: based on the water body area) should be used for double disinfection. After the pond is disinfected, choose a beach with a hard bottom for smoothing and sanding (preferably choose a beach near the ring ditch, and make 畦, 畦 4-5 meters wide, 25-30 cm high), and sand the area is about Account for 1/3-1/4 of the total area of ​​the pond. It should be adjusted according to the pond water body. If the aquaculture area is too large to affect the growth rate of the clams, if the area is too small, the aquaculture capacity of the ponds cannot be fully utilized. 2, seedlings should be chosen to vote for cloudy days, dawn or dusk. Especially in the hot climate, seedlings and specifications are particularly important, cast seedlings should be spread evenly and should not be piled. Specifications 50-60 / 500 grams of seedlings mu put, grasped in about 500-700 kg. The area of ​​cultured clams is less than 1/4 of the total area of ​​shrimp ponds. The volume of seedlings may be increased as appropriate. However, it should not exceed 1,000 kg. The area of ​​culture clams should be less than 1/3 of the pond area. The amount of seedlings should be reduced as appropriate. The size of seedlings should be 300-500 pieces. 500g per mu should not exceed 200 kg. 3. Cultivation management 1. Water temperature and water quality monitoring To monitor water temperature and water quality, measure the water temperature every morning (6:00) and noon (14:00), and observe the water color. Daily water storage is mainly based on water quality. The PH value in the pool should be controlled between 7-8, dissolved oxygen should be above 4mg/l, and the water color should be mainly yellow and green. The transparency should be controlled at 20-. 40CM. 2, regular sampling and measurement once every two weeks, measuring and observing its growth. If it is found that the density is too large or the piles of clams are found in batches, they should be evacuated in time. As long as the environment is appropriate, the literary genus is rarely moved. 3, bait management is mainly to cultivate food biomass in the pond. In the early spring, small fresh fish and shrimp paste is used to splash water with fertilizer and increase the amount of organic debris in the pond; compound fertilizer and organic fertilizer are used for water in sunny summer and autumn; and soy milk is used for feeding and feeding in late autumn and winter. 4. Disease prevention and control measures The use of quicklime (10kg/mu) or chlorine dioxide (0.125kg/mu) and other drugs for water disinfection and disease prevention every other month. 5. The enemy's deterrence blocks the enemy and prevents escape. The block height is generally 1.2 meters high and 0.2 meters buried in the beach surface. However, it must be inspected frequently and it must be promptly repaired if dumping or damage is found. After each drainage, it should be carefully checked whether there is any invasion of green crabs and other enemies on the beach surface. Once discovered, the enemy will be cleared in time. 6, to prevent the beach surface of the growth of the bryophyte is basically a regular half-day tide, the pond culture clams change the water every half a month, change the water to let the beach surface dry 1-2 days, into the site of the mud, to Immediately clean up to effectively prevent the breeding of beach bryophyte. Especially in spring and autumn, it is very easy to grow the sphagnum moss on the squid and it should be manually removed or killed.
