Description

Pond culture system based on water cyclic utilization

Technical Field

The invention relates to the technical field of aquaculture water environment treatment and ecological aquaculture, in particular to a pond aquaculture system based on water body recycling.

Background

Pond culture is an important culture mode developed in recent years, and the culture environment is relatively closed, so that the controllability is high, and compared with the traditional open culture, the economic benefit of the pond culture is higher. In view of the high benefit of pond culture, many areas along the coast of China are developing pond culture industry, and many open sea areas are reclaimed to become culture ponds. With the improvement of culture techniques and means, a plurality of high-density and industrial culture ponds have been developed in recent years, wherein the culture of litopenaeus vannamei in the east-sea area is particularly obvious. At present, the industrial aquaculture density of the litopenaeus vannamei is high, natural baits cannot meet the ingestion requirements of the litopenaeus vannamei, and therefore the industrial aquaculture ponds for the litopenaeus vannamei are all in a bait casting mode, the rising of particles such as bait residues and shrimp excrement in aquaculture water is caused, and the aquaculture objects (the litopenaeus vannamei) can discharge metabolic wastes containing nutrient elements such as nitrogen and phosphorus, so that the concentrations of substances such as particle suspended matters, ammonia nitrogen, active phosphates and the like in the tail water of the litopenaeus vannamei aquaculture pond are high, if the litopenaeus vannamei aquaculture objects are directly discharged into the environment without being treated, certain harm can be brought to the environment, and with the continuous promotion of the ecological civilization construction process, the beautiful ecological environment becomes the current urgent need, and with the deep national environment protection and supervision work, the tail water treatment of the aquaculture ponds becomes a imperative work. In summary, a cultivation mode based on water body recycling is developed, and important key problems of pond cultivation tail water discharge are solved on the basis of realizing practical requirements of considering economic benefits through collocation among various cultivation varieties or cultivation modes, and the key problems need to be solved currently.

At present, some researchers develop some systems for treating breeding tail water, but the treatment modes of different systems are different greatly, the treatment effect is not completely satisfactory, and at present, the researchers also develop a breeding mode for breeding the litopenaeus vannamei in an overhigh pond, but a pond breeding mode based on water body recycling is rare, and the research on realizing breeding type output through different structures of a whole circulating system is not reported. This pond culture system has realized three targets: firstly, prawn cultivation is taken as a main part, shellfish cultivation is matched, and multi-variety output is realized; secondly, self-treatment is carried out in the prawn culture tail water system, so that zero discharge or standard discharge of the culture tail water is realized; and thirdly, the culture mode and the culture concept are improved, the culture benefit is improved, and the culture economic benefit is low.

Therefore, the pond culture mode based on water body recycling aims to solve the problem of comprehensive treatment of the prawn pond culture tail water, the reduced culture tail water is used for shellfish culture, prawn culture is carried out on the water after the shellfish culture, and recycling of the culture water body is finally achieved.
