Pond snakehead breeding and hatching pond

Abstract

The invention relates to the field of fish breeding and hatching, in particular to a pond snakehead breeding and hatching pond which comprises a cuboid hatching pond. A water inlet is arranged at one end of the hatching pond, a water outlet is arranged at the other end of the hatching pond, a filtering net is arranged at the front end of the water outlet, each of a left half and a right half of the hatching pond is provided with water return walls which are equidistantly spaced and parallel, water outgoing holes are formed in the bottom, among the water return walls of the left half, of the hatching pond, water outgoing holes are formed in the bottom, among the water return walls of the right half, of the hatching pond, a frame rod is arranged right above the middle of the hatching pond, and turbines are arranged on the frame rod. By the pond snakehead breeding and hatching pond, hatching success rate of pond snakehead is increased, and hatching and breeding cost of the pond snakehead is saved.

Description

technical field [0001] The invention relates to the field of fish breeding and hatching, in particular to a pond snakehead breeding hatching pond.

AI Technical Summary

Problems solved by technology

At present, individual units have carried out small experiments on natural water temperature artificial hatching and breeding of pond snakeheads, using artificial induced spawning, natural spawning, and natural water temperature hatching methods. This method is easily affected by the external environment, especially water temperature changes. The natural guardianship of fish, fertilized eggs are prone to mold and death, so it cannot form a batch and stable seed production capacity
