Description

Water internal circulation system of high-yield culture pond for marsupenaeus japonicus

Technical Field

The utility model belongs to the technical field of the cultured equipment, especially, relate to a japanese marsupenaeus prawn high yield culture pond water inner circulating system.

Background

Marsupenaeus japonicus, also known as prawns, flower shrimps, Japanese shrimp, and zebra shrimp, are widely distributed in India and Pacific areas, and also in south coast of Jiangsu province in China. The marsupenaeus japonicus has the advantages of rapid growth, strong disease resistance and no death after leaving water for a long time, is suitable for long-distance dry transportation and live sale, and is an important earning fishery product.

World bursa shrimp farming began with stocking of Japanese bursa shrimps in 1902, the main purpose of which was to obtain seasonal differences. Since 1933, the research on the culture of penaeus japonicus was really started by doctor of Tengyuang, and until now, penaeus japonicus was still the main cultured shrimp in Japan. China succeeded in the trial culture of marsupenaeus japonicus from the eighties and has achieved good economic benefits. At present, the breeding area of the marsupenaeus japonicus in China is about 100 ten thousand mu. The shrimp farmer mostly adopts a cultivation mode of mixed cultivation and rotation of catching and rotation of putting, for example, three shrimp fries are generally put in the coastal areas of south east of Shandong, and are mixed cultivated with shellfish and portunus trituberculatus, but the yield is very low, generally 20-30 kilograms per mu, and rarely reaches 50 kilograms, so that the marsupenaeus japonicus can not meet the requirements of domestic and foreign markets for a long time.

Through years of cultivation practices, the mode of sand-spreading intensive culture of the marsupenaeus japonicus in the high-level pond is continuously developed and perfected, but some technical problems need to be overcome, such as accumulation of pollutants in a sand layer at the bottom of the pond, blackening of the sand layer and the like in the cultivation process. At present, a whole-pond sand-spreading mode is mostly adopted in a high-level pond sand-spreading intensive culture mode for marsupenaeus japonicus, and due to the fact that the sand surface is thick and uneven, a large amount of pollutants such as residual baits, excrement and the like are attached to the bottom of the pond and cannot flow and concentrate to a central bottom sewage discharge outlet, and the pollutants in a sand layer at the bottom of the pond are accumulated. Because the marsupenaeus japonicus has a sand-diving habit in the daytime, the growth of the marsupenaeus japonicus can be directly influenced by the pollution of a sand layer at the bottom of the pool, if the dissolved oxygen at the bottom layer is insufficient, the pollutants are putrefy and fermented, the ammonia nitrogen and the nitrite in the water body are increased, and finally the marsupenaeus japonicus is killed; and the water in the sand layer is static dead water, pollutants are quickly rotten and smelly, the sand layer is blackened, and the marsupenaeus japonicas cannot inhabit, so that the marsupenaeus japonicas are killed.
