Functional pond for culturing mass freshwater fishes

Abstract

A functional pond for culturing mass freshwater fishes is characterized in that a rectangle culture pond body (1) is divided into a first part (101) and a second part (102) by a water diversion wall (2), the water diversion wall (2) is of a T shape, a T-shaped transverse separating wall body (201) of the water diversion wall (2) separates the first part (101) from the second part (102, an interval is formed between the tail end of a T-shaped longitudinal wall body (202) and the pond wall of the rectangle culture pond body (1), and the second part (2) comprises a front pond portion (102a ) and a rear pond portion (102b) which are communicated with each other. According to the functional pond for culturing the mass freshwater fishes, traditional stereoscopic culture is divided according to ecological niches, so that the fishes in different ecological niches can take full advantages of different ecological niche resources, fish growth is facilitated, and the ecological efficiency and culturing benefits of pond culturing are improved; a fish feeding culture area is divided into a growth area, a feeding area, a fecal treatment recycling area and the like, the formation of flow, collection of dirt, the recycling of pollutants, regulation and control over a water body and the like are facilitated, and meanwhile, installation condition is provided for the achievement of automatic mechanized fishing and industrialized management.

Description

technical field [0001] The invention belongs to the field of aquaculture facilities, and in particular relates to pond cultivation of bulk freshwater fish, in particular to a functional pond capable of improving the efficiency of mixed cultivation of bulk freshwater fish. Background technique [0002] With the development of social economy, people's demand for aquatic products is increasing day by day. Aquaculture of large quantities of freshwater fish in ponds has gradually become the main source of aquatic product supply. In order to meet people's increasing demand for aquatic products, since the 1980s, research on pond aquaculture technology has been carried out at home and abroad. With the improvement of aquaculture technology, the research on pond infrastructure is also increasing. Drainage facilities, food platforms, slope protection, etc. have been proposed to construct technical methods, but the existing research lacks the research on the effect of pond structure on...

AI Technical Summary

Problems solved by technology

[0004] (1) The structure of the traditional pond is simple, and the breeding production efficiency is not high;

[0005] (2) Polyculture is commonly used in traditional pond culture. Although different ecological niches in the water body can be fully utilized, there are also problems of emergency impact on fish growth and inconvenient fishing;

[0006] (3) Due to the large area of ​​the traditional pond, the water flow in the pond varies greatly, there are many dead ends, and the water environment is difficult to control;

[0007] (4) In traditional pond culture, fish excrement and feces residual bait are freely deposited on the bottom of the pond, causing deterioration of the culture environment and serious sediment pollution;

[0008] (5) Traditional pond farming adopts the method of artificial net fishing, which takes up a lot of labor, labor intensity is high, and the fishing effect is not high
