Sturgeon culturing pond

Abstract

The invention discloses a sturgeon culturing pond, which has the shape of square outer part and circular inner part, wherein the middle of the pond is the pond taken as a culturing region with straight edges and circular angles; the four square corners out of the pond with the straight edges and the circular angles are formed into four corner ponds which are respectively to be a first corner pond, a second corner pond, a third corner pond and a forth corner pond; the middle parts of the first corner pond and the second corner pond are provided with water charging openings which are communicated with water feed pipes and can charge water for the pond with the straight edges and the circular angles along the tangential direction of the arc pond walls of the corner ponds; the bottoms of the inner walls of the third corner pond and the forth corner pond are provided with water discharging openings which are communicated with the pond with the straight edges and the circular angles; the water discharging openings are provided with escape-proof networks for preventing the sturgeons from escaping; the upper edges of the outer walls of the third corner pond and the forth corner pond are provided with triangular-notch weir water discharging structures; the bottoms of the inner walls of the first corner pond and the second corner pond are respectively provided with a through hole which can be communicated with the pond with the straight edges and the circular angles; the through holes are provided with escape-proof networks; and the first corner pond and the second corner pond are internally embedded with oxygenating devices for increasing the oxygen content of water in the pond with the straight edges and the circular angles.

Description

technical field [0001] The present invention relates to a sturgeon breeding pond, more specifically, relates to a sturgeon breeding pond suitable for high-density three-dimensional industrial circulation aquaculture. Background technique [0002] Aquaculture is an important part of traditional agricultural production and plays an important role in the process of human social and economic development. Since the 1950s and 1960s, the pollution of rivers, rivers, lakes, reservoirs and other water bodies has gradually increased. On the one hand, the food safety of aquatic products has become increasingly prominent. The eutrophication aquaculture sewage in turn causes serious pollution to the surrounding water bodies. Therefore, industrialized recirculating aquaculture technology came into being. Practice shows that whether the design shape of the aquaculture pond in industrial recirculating aquaculture is reasonable or not has a great impact on the fish growth environment, qual...

AI Technical Summary

Problems solved by technology

Existing breeding pond adopts square pond, circular pond or octagonal pond mostly from the point of view of shape (such as figure 1 shown), but these aquaculture ponds generally have problems such as poor water fluidity, low land utilization rate, lack of flexibility and controllability in drainage and sewage, and difficulty in controlling the water level and flow in the aquaculture pond, which leads to increased operating costs and poor benefits
