Problems solved by technology

[0005] The methods involved in the above patents all need to set up a tail water treatment area outside the pond. Although it can reduce or stop the tail water discharge, it will waste a certain breeding area and reduce breeding income. Some small farms are not willing to adopt this method. method

Embodiment

[0029] A kind of fish centralized cultivation system of circulating water in the freshwater pond of the present invention, such as figure 1 As shown, it includes concentrated fish breeding area 1, solid waste in-situ treatment area 2, and nesting area 3; image 3 As shown, the concentrated fish breeding area 1 is a rectangular area, which is composed of breeding tanks 5, wherein the breeding tanks 5 include two rows of equally spaced and evenly distributed wooden piles 6 arranged on both sides and integrally fixed and laid on the bottom and both sides of the wooden piles. The plastic film 7 on the pile 6 and the two ends of the breeding tank 5 are blocked by the mesh sheet 8, which can raise fish in captivity without affecting the water flow; the plastic film 7 is made of HDPE anti-seepage film and has good sealing performance. Such as figure 1 As shown, the water in the concentrated fish breeding area 1 is introduced from the nesting area 3 of the pond through the aeration d...

Abstract

The invention discloses a circulating water fish intensive breeding system and method for a fresh water pond, and belongs to technical field of aquaculture. A pond water area is partitioned into a fish intensive breeding area, a solid waste in-situ treatment area and an intercropping area; the fish intensive breeding area and the solid waste in-situ treatment area are positioned inside the intercropping area; the solid waste in-situ treatment area is close to one end of the fish intensive breeding area; a boosting water-pushing device is arranged at the other end of the fish intensive breeding area; the boosting water-pushing device can be used for introducing water in the intercropping area into the fish intensive breeding area; water in the fish intensive breeding area is drained into the intercropping area after passing through the solid waste in-situ treatment area. A fish intensive breeding way can be adopted, so that bait and labor force are saved, and daily management, sales and fishing are facilitated; stable water quality inside the pond can be enhanced by the waste in-situ treatment area and the intercropping area, so that the quantity of exchanged water can be reduced greatly, and breeding pollution is lowered.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a centralized fish breeding system and method for circulating water in a freshwater pond. Background technique [0002] The stability of water quality in the process of aquaculture is the premise of maintaining high yield. Traditional freshwater pond culture mainly maintains water quality by increasing oxygen and changing water. Pollution causes frequent occurrence of aquatic diseases, and by increasing the water exchange rate, the water quality in the pond fluctuates greatly, which easily causes the stress response of farmed animals. Therefore, how to reduce the tail water discharge in the freshwater pond culture process is a key issue for the sustainable development of the freshwater aquaculture industry. The low-carbon, high-efficiency, and environmentally friendly circulating water aquaculture model is the development direction of modern freshwater aquaculture. At prese...
