Pond conditions Pond culture area is generally 3 acres ~ 5 acres is appropriate, rectangular or square, water depth 80 cm ~ 120 cm, sediment quality is good as sand, sediment content of more than 70%, and require loose, rough. Tangtang is sturdy and durable, with good water retention in ponds, which naturally drains pool water. Adequate water sources, good water quality, no industrial and domestic sewage inflows nearby. Pre-breeding preparation Pond cleaning and disinfection. After closing the insects, seal the dam dry pond, repair the pond embankment, remove the bottom of the pond, and dig a ring ditch around the pond. The ditch is 50 cm wide. The pond is divided into blocks of 200 cm to 250 cm in width and 50 cm wide is left between the block and the block. The ditch, water supply and drainage and operation. The surface of the pond culture was divided into sections of soil and rammed soil, and the surface of the block was flattened and wiped with a wooden board. From both sides of the block, it was pressed into a “road shape†to the center, and the water in the block area could not be made. For the flattened pond, the drug should be applied for 10 days before stocking. The bleaching powder can be used to make the whole pool splash. The dosage per acre is 8 kg to 10 kg. After the fertilizer and water treatment period expires, water is stored to cultivate basic food. The water inlet is filtered through a mesh bag with an aperture of 80 mesh, and the inlet water is 40 centimeters to 50 centimeters. Fertilizer can be used for fermentation of farmyard fertilizers, with an amount of 200 kg per mu, spread on the surface of the culture block, or 3 kg of nitrogen fertilizer and 1 kg of phosphate fertilizer per mu. Conditional farmers can use organic fertilizers mixed with microbial agents for better results. Seed stocking and management The time of sandworm investment is mainly before and after the Ching Ming Festival every year. The seedlings are 50 kg per mu. The specifications are more than 400 pieces per kilogram. The stocks for stocking require individuals to be intact without injury and the color is dark brown. Stocking should be chosen to be sunny. The pond's seawater salinity is about 25‰, and the difference between the breeding water body and the seedling salinity should not exceed 5‰. Seed stocking density of 30 per square meter is appropriate, calculate the number of seedlings required before stocking, and then spread the seed evenly on the surface of the culture block, let it naturally into the sand. After the sand worms are stocked, they are put into management. Frequently inspect the surface of the culture and regularly clear the ditch. After stocking for 2 days to 3 days, Xia Tang inspected the survival rate of the seedlings and found that the survival rate was low. The seedlings should be filled immediately. After each week, the ponds should be inspected. The ditch and the dam should be frequently cared for. Into the summer, timely clear the channel, the block surface into a "road-shaped", can not let the block area of ​​water, so that the block surface is solid up and form a stable sandworm living environment, to facilitate its growth. In case of typhoon and heavy rainstorm, the proportion of seawater in the culture ponds will often cause a sudden drop. Therefore, after the rain, the pond water should be drained in time, and fresh seawater should be included when the tide rises to prevent the death of the star beetle due to the low proportion of seawater. Precautions During the growing season, the water level is adjusted according to the climate change in different seasons. The weather in spring and autumn is warm and shallow, and it is hot in summer and cold in winter. Change the water once a week, dry ponds 2 days to 3 days a month, the use of dry pond machine, the lower pond to clear the fish, shrimp, crabs and canola and other predators. The sandworms feed on benthic diatoms and organic debris. During the cultivation, according to the conditions of the ponds, fertilization of algae or feeding of some artificial baits can be properly conducted as a supplementary diet.
