Description

Ecological breeding circulating system

Technical Field

The invention relates to the technical field of cultivation, in particular to an ecological cultivation circulating system.

Background

The traditional marine products are transported from coastal areas to inland areas, and the survival rate of the marine products and the like in the transportation process influence the value of the marine products; with the continuous development of science and technology, inland gradually appears self-matched artificial mariculture technology, and corresponding patent technology is also generated, for example, the invention patent with publication number of CN109169424A discloses a seawater fish pond ecological intensive culture system, which comprises a culture area, a purification area and a fish dung collection area, wherein the culture area is defined by a plurality of parallel isolation walls and barrier nets positioned at two ends of the isolation walls, seawater fish are cultured in the culture area, and the bottom of the culture area is an obliquely arranged stainless steel plate; the outer side of the higher end of the stainless steel plate is provided with a water pushing device, the fish and excrement collecting region is positioned on the outer side of the lower end of the stainless steel plate, the culture region, the purification region and the fish and excrement collecting region are communicated, and the culture region accounts for 2-5% of the total area of the pond; aquatic plants and microorganism degradation microbial inoculum can be put in the purification area, and the aquatic plants and microorganisms are utilized to decompose, absorb and utilize nutrient substances in the water body, so that zero emission of the aquaculture water body is realized, and the environmental pollution is reduced.

However, the prior cultivation still has the following technical problems:

1. the technical culture mode is based on further improvement of a seawater pond in a coastal region, and cannot be applied to inland seawater scarce regions and solve the problem of soil salinization caused by seawater discharge in pond culture.

2. The seawater fish is placed in a culture area, and the penaeus vannamei boone is also cultured in the culture area, and the penaeus vannamei boone can eat the residual crushed aggregates and powder of the seawater fish, so that the water quality is prevented from deteriorating; however, in the actual culture process, the problem that food residues are not treated timely and thoroughly by fish, shrimp and shellfish is found, so that the sediment and excrement are settled to cause the deposition deterioration of a bottom matrix, the water body index is further influenced, and the effect of avoiding the water quality deterioration is not obvious.

3. In the technology, the fish manure is collected independently and needs to be discharged all the time, otherwise, the land salinization is caused; the treatment process is troublesome and the cost is increased.
