Multi-level fish alternate culturing pond

Abstract

The invention discloses a multi-level fish alternate culturing pond. The multi-level fish alternate culturing pond comprises a plurality of culture pond bodies and filtering circulation systems arranged on the side faces of the culture pond bodies and are matched with the culture pond bodies respectively. The culture pond bodies are sequentially arranged in parallel, every two adjacent culture pond bodies are communicated through a communication port, fish control valves used for regulating the density of the culture pond bodies are arranged on the communication ports, flow rate meters used for monitoring the water flow rate of the culture pond bodies and power pumps used for controlling the water flow rate of the culture pond bodies are arranged near the communication ports, water inlet pipes of the filtering circulation systems are arranged on the upper portions of the lateral walls of the culture pond bodies and water draining pipes are arranged at the bottoms of the lateral walls of the culture pond bodies. The multi-level fish alternate culturing pond is simple in structure and brings convenience to multi-level alternate culture of fishes; due to the fact that the whole operation process is high in controllability, the problems that the cultured fishes suffer from diseases and die due to oxygen deprivation and mechanical injuries are not prone to occurring.

Description

technical field [0001] The invention belongs to fish breeding technical devices, in particular to a fish multi-stage rotation breeding pond. Background technique [0002] In the whole process of fish breeding, it needs to be divided into multiple breeding stages and raised in different breeding ponds. Each type of breeding pond is specially raised for fish of a certain size, and it is raised for a certain period of time (40d-60d). After reaching a certain size Then put it into another type of breeding pond. This kind of breeding operation is called pouring the pond. Every time the pond is poured, the fish breeding density will be sparse. Make full use of the water body space and the purpose of bait organisms. [0003] At present, the multi-stage rotation culture in fish farming production mainly adopts the operation method of manually pulling nets to catch them and putting them into another culture pond. Disease and death have seriously hindered the large-scale farming of ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-stage rotation culture pond for fish, which overcomes the above-mentioned deficiencies such as the lack of oxygen, mechanical damage and disease and death of fish caused by the above-mentioned artificial start-up and thin-release, with simple operation and strong controllability. There is no damage to the seedlings, which is conducive to breeding management, reduces the occurrence of fish diseases, and improves breeding efficiency
