A tank-type intensive circulating aquaculture model for pond fish

Abstract

The invention discloses a pond fish water tank type intensive recirculating aquaculture mode and relates to the technical field of aquaculture. According to the pond fish water tank type intensive recirculating aquaculture mode, a plurality of independent aquaculture water tanks arranged in parallel are formed in an aquaculture pond, the front side face and the back side face of each aquaculture water tank are walls with the thickness of 30 cm and the height of 2-3 m, double-layer fish barring nets are installed at both the left end and the right end of each aquaculture water tank, micropore oxygen-increasing equipment is arranged at the water inlet end of each aquaculture water tank, and a low wall with the height of 30 cm is arranged at the water outlet end of each aquaculture water tank; impeller type oxygen-increasing machines are installed in the aquaculture pond in the density of one machine per 2 mu, and a water-retaining wall is arranged in the middle of the aquaculture pond. By means of the pond fish water tank type intensive recirculating aquaculture mode, the aquaculture yield can be improved by 30%-50%, the bait utilization rate is improved, the occurrence of fish diseases is reduced, the survival rate is improved, the medicine cost is reduced, the pond can also be prevented from aging, and the pond cleaning cost is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a tank-type intensive circulating aquaculture mode for pond fish. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. With the advancement of science and technology and the needs of people's lives, fish farming in ponds has become a way to get rich. The current breeding ponds are mainly based on the high-density intensive intensive farming model, and there are often defects in the following aspects in the breeding process: (1) In order to achieve the highest water body utilization rate and pursue breeding benefits in the same pond, the farmers Often blindly pursue production, usually the stocking density of various fish species is extremely high, resul...

Problems solved by technology

[0003] The invention provides a tank-type intensive circulating aquaculture mode for pond fish, which overcomes the deterioration of the water body caused by the overload of the aquaculture capacity in the aquaculture process of the current aquaculture pond, the metabolites and excreta of the aquaculture fish, and the reduction in the utilization rate of the bait , decreased resistance, poor sewage capacity, and frequent breeding diseases, provides a way to build a breeding runway and retaining wall in the pond to concentrate most of the cultured fish in the runway, and use microporous aeration equipment to make The water flow is generated in the runway to increase oxygen for the farmed fish in the tank and collect the feces produced by the centralized farmed fish, thereby increasing the breeding output, improving the utilization rate of bait, reducing the occurrence of fish diseases, increasing the survival rate, reducing the cost of medication, and Pond fish tank type intensive recirculating aquaculture pond that can prevent pond aging and reduce the cost of pond clearing
