Description

A batch production farming systems for shrimp

Technical Field

The utility model relates to a shrimp aquaculture field especially relates to an industrial aquaculture system for shrimp.

Background

The Litopenaeus vannamei commonly named as Penaeus vannamei has the advantages of delicious meat, rich nutrition, large size, fast growth, low nutritional requirement, strong disease resistance and the like, has strong adaptability to environmental change, and can grow at the temperature of 18-32 ℃ and the salinity of 1-40 per mill. The litopenaeus vannamei has low protein demand and high meat yield, is a good variety for intensive culture, and is the first prawn culture variety in the world. The litopenaeus vannamei is introduced for the first time in 1988 by the oceanic research institute of the academy of sciences of China, the difficulty of artificial propagation is broken through in 1992, and then the litopenaeus vannamei is widely cultivated in China, and parent shrimps are imported from the United states for shrimp fry production continuously from various places. The litopenaeus vannamei becomes the leading breed for the culture of the litopenaeus vannamei in China.

A large amount of wastes such as excrement, shrimp shells, residual baits and metabolites are generated in the industrial high-density culture process of the prawns, the accumulation of the wastes spoils the water quality and causes the pathological changes and death of the prawns, and therefore the lasting and efficient removal of the culture wastes becomes a problem which must be solved in the daily management of the industrial high-density culture of the prawns. At present, no simple and efficient decontamination and pollution discharge method exists in industrial prawn culture, and many semi-hydration culture plants utilize large water flow to impact water to form water flow so as to flush away waste, but waste of a large amount of culture water is caused, and culture cost is increased. At present, aeration materials and devices used in the industrial prawn culture process are all single aeration facilities, and the functions of the aeration materials and the devices are not fully utilized; the up-and-down flowing type aeration is easy to cause the up-and-down rolling and crushing of the excrement and the residual bait, and the work of decontamination and cleaning is complicated. In addition, the water circulation frequency of a common prawn circulating water culture system is low, and sewage is easily deposited on the bottom of a traditional square round-corner pond, so that the water quality index of the bottom of the pond exceeds the standard, the bottom of the pond is anoxic, culture wastes cannot be timely cleaned, and further the culture fails.
