Aestivation pond aestivation system for sturgeons in southern land

Abstract

The invention relates to an aestivation pond aestivation system for sturgeons in southern land. The aestivation pond aestivation system aims to solve the problems that sturgeons cultured in the south can not aestivate safely, and visual management can not be achieved when deepwater net cages are adopted for culturing. The aestivation pond aestivation system comprises a cold water source and a water taking device and is characterized in that a plurality of aestivation ponds are arranged beside the cold water source, the first main pond is connected with the parallel assistant ponds through double-layer channels, the upper parts of the double-layer channels are main sturgeon transfer channels, the lower parts of the double-layer channels are water diversion channels, an assistant sturgeon transfer channel is formed between every two adjacent assistant ponds, and arc-shaped sturgeon stop nets are arranged at the water diversion channels. The survival state of sturgeons can be observed at any time in summer, flood season safety protection is reliable, the communicated ponds are provided with the high-water-level and low-water-level dual sturgeon transfer channels, accurate sturgeon individual check can be achieved, the living state of sturgeons can be closely observed, and the aestivation survival rate of sturgeons is increased.

Description

technical field [0001] The invention relates to aquatic product breeding technology, in particular to a system for spending summer in a pond in southern land for sturgeon. Background technique [0002] Sturgeon is a kind of cold-water fish, mainly distributed in areas with abundant cold water resources in the north and west. For the southern region with higher water temperature, the use of deep reservoirs with large water surfaces has also been successful, and the optimal temperature growth time is longer than that in the north. The sturgeons cultured in the south are larger and grow faster than those in the northern and western regions. . However, the high temperature in the south has restricted the development of the sturgeon industry. In the south, although the deep-water net cages can be used for the summer of the sturgeon, the sturgeon lives in the deep water during the summer, and there are relatively many uncontrollable factors. For those with weak constitution, low...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the southern cultured sturgeon spends the summer safely and cannot carry out visual management when adopting deep-water cage culture, and provides a system with a reasonable structure, which can make full use of the natural resources of the reservoir, and can observe the living state of the sturgeon at any time.
