Abstract

The invention relates to a pond-based ecological intensive aquaculture system for marine fishes, which includes an aquaculture area, a purification area and a fish excrement collection area. The aquaculture area is composed of a number of parallel isolation walls and blocking nets at the two ends of the isolation walls. There are marine fishes in the aquaculture area. The bottom of the aquaculturearea is an inclined stainless steel plate which inclines at a degree of 5-20. A water pushing device is arranged on the outer side of the higher end of the stainless steel plate. The fish excrement collection area is located on the outer side of the lower end of the stainless steel plate. The aquaculture area, the purification area and the fish excrement collection area are connected. The aquaculture area accounts for 2-5% of the total pond area. The pond-based ecological intensive aquaculture system for marine fishes has the advantages as follows: daily management is convenient; the aquaculture cost can be reduced; the aquaculture yield and efficiency can be improved; a win-win result can be achieved for economic and environmental benefits; the operation efficiency of the ecological function units can be maximized; and the allocation of resources can be optimized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecologically intensive culture system for seawater fish ponds. Background technique [0002] At present, the artificial breeding of most marine fish mainly adopts a single extensive farming model, which not only wastes water, is inefficient, affects the economic benefits of farming, but also easily pollutes the environment: single extensive In the aquaculture mode, the fish excrement and surplus bait produced in the process of aquaculture accumulate in the water body, which will lead to a decrease in the dissolved oxygen in the water body, thereby causing eutrophication in the water body, and at the same time, it is easy to cause fish diseases, which seriously affects the The economic and ecological benefits of aquaculture, and the discharge of aquaculture sewage is not conducive to the sustainable development of the marine environment. In addition, because th...
