Bionic loach breeding device and loach breeding method

Abstract

The invention provides a bionic loach breeding device and a loach breeding method. The bionic loach breeding device comprises a breeding barrel, an incubation larva culture barrel, a flow supply pipeand a larva gathering pipe, the lower end of the incubation larva culture barrel is connected with the larva gathering pipe, the upper flow supply pipe is overlapped at the edge of the open end of theupper end of the breeding barrel, one end of a diversion pipe is communicated with the upper flow supply pipe while the other end of the same extends into the breeding barrel along the inner wall ofthe same, and multiple diversion holes are formed in the upper portion of the outer wall of the diversion pipe. The loach breeding method includes: releasing male loach parents and female loach parents proportionally, raising loach larvae in the breeding device, and collecting the loach larvae from the larva gathering pipe. By adopting the technical scheme, spawning and hatching of loaches are centralized in a same special device, so that production cost of the breeding device is lowered greatly, breeding period is shortened, labor intensity of artificial breeding is lowered, parent death rateis lowered, loach larva culture survival rate is increased, and breeding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to an ecological imitation loach breeding device and a loach breeding method. Background technique [0002] At present, devices for imitating ecological breeding of stream fish have been born. For example, CN104872006B-a method for artificial reproduction of light-lipped fish and CN 109349171A-a method for imitating ecological reproduction of catfish. However, they are all devices that separate egg laying and hatching, and there are limitations in manpower input, simplicity of the device, and reproductive effect. Many breeding and hatching devices for loach are also separated, and many breeding patents for loach are based on artificial reproduction. Because loach is a small fish, it has difficulties in administering hormones, complicated egg squeezing operations, high cost, and low efficiency of induced labor. , Broodstock mortality and other issues. At ...

AI Technical Summary

Problems solved by technology

Many breeding and hatching devices for loach are also separated, and many breeding patents for loach are based on artificial reproduction. Because loach is a small fish, it has difficulties in administering hormones, complicated egg squeezing operations, high cost, and low efficiency of induced labor. , high mortality of broodstock and other issues

At present, there are no patents on the imitation ecological breeding of loach, and there is no patent on the imitation ecological integrated breeding device for loach
