Description

Hatching system Technical Field The utility model relates to the field of fish fry hatching, in particular to a hatching system. Background At present, in the fry hatching process, loop hatching is generally adopted, and the process comprises four steps of spawning in a fish pond, shoveling eggs at the bottom of the pond, rubbing egg masses and loop hatching. In the spawning process of the fish pond, the fertilized rate of the fish eggs is large, the unfertilized rate is at least 2%, and the unfertilized rate can be up to more than 40%. In the process of shoveling eggs at the bottom of the pool, many fish eggs can be injured or shoveled to form dead eggs and empty egg skins. The egg mass under the shovel needs to be rubbed into single grains or tiny lumps to ensure oxygen supply. The rubbed eggs can damage part of the fish eggs, and dead eggs and egg skins which are generated can not be screened out, so that the rubbed fish eggs can carry the dead eggs and egg skins and put into a loop for hatching. When fertilization rates are low, the dead eggs gradually mould to form hydromyces eggs, which fill the entire loop and block the barrier net, eventually leading to water quality deterioration and failure of hatching. Therefore, there is a need for a system that can effectively hatch fish eggs without damaging the fish eggs.
