Device and method for automatically collecting fish eggs

Abstract

The invention discloses a device and a method for automatically collecting fish eggs, comprising a box body, an iron gauze separator, a filter screen separator and waterweeds, wherein the iron gauze separator and the filter screen separator are arranged in the box body from top to bottom, the mesh diameter of a filter screen of the filter screen separator is smaller than the mesh diameter of an iron gauze of the iron gauze separator, a gap is formed between the filter screen separator and the bottom of the box body, a discharge port is arranged at the bottom of the box body, the iron gauze separator is horizontally inserted into a first group of slot, the filter screen separator is horizontally inserted into a second group of slot, the first group of slot and the second group of slot are horizontally arranged on the side surface of the box body, which is vertical to a handle of the iron gauze separator, and the waterweeds are horizontally arranged on the top of the iron gauze separator. The device and the method for automatically collecting fish eggs have the beneficial effects that the device is simple in structure, low in price and has less influence on adult fish, the egg laying rate is high, the injury to fish eggs is reduced, the fertility rate is increased, the labor intensity is relieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of containers containing live fish, in particular to a device and method for automatically collecting fish eggs. Background technique [0002] The zebrafish is one of the standard model test animals because of its small size, short spawning cycle, high spawning capacity, and rapid growth and reproduction. The acute toxicity test of zebrafish is an important means to detect industrial pollution and water pollution; because the nervous system, internal organs, blood and visual system, especially the cardiovascular system, are 85% homologous to humans at the gene level, and their early development is similar to that of humans. Very similar, zebrafish has become the best model organism for the study of human-related diseases, with advantages that other vertebrates cannot match. The in vitro fertilization and development of zebrafish embryos are synchronous and fast. Embryo development is fully transparent. With the help ...

AI Technical Summary

Problems solved by technology

In traditional artificial breeding, zebrafish adult fish are often moved to spawning boxes or special fishing nets, and repeated fishing and disturbance are likely to cause damage to the fish body; and when collecting fish eggs, fish eggs are collided and rubbed many times through straws, etc. Susceptible to mechanical damage, affecting hatchability and embryo quality
