Abstract

TECHNICAL FIELD
[0001] The present application relates to the technical field of aquaculture equipment, and particularly relates to a box for assisting in hatching fish eggs. BACKGROUND
[0002] In China, artificial hatching of fish is mainly to take fertilized eggs out and make the fish eggs hatch into fry by improving specific environmental conditions such as controlling water temperature, water flow, water dissolved oxygen and monitoring water quality. Artificial hatching can improve the hatching efficiency and hatching rate of a part of fish eggs and meet the requirements of industrialization.
[0003] With the continuous development of the aquaculture industry, higher requirements are put forward for the hatching efficiency and quality of fry. Traditional hatching facilities such as hatching tanks and hatching rings have many problems, for example, large equipment footprint, difficult to control water flow rate, small water area exchange, etc. In addition, high-density fish egg hatching is prone to problems such as adhesion of fertilized eggs, mutual extrusion and hypoxia, which affect the hatching rate.
[0004] Many fish eggs have stickiness. After encountering water, the stickiness on the surface of the egg membrane is activated, which brings challenges to artificial insemination and hatching technology. At the same time, fish eggs have strict requirements for water quality, temperature and water flow during the hatching process. Unfit conditions may cause poor development or death of fish eggs.
[0005] Although the existing fish egg hatching device solves some problems to a certain extent, it still has some defects. For example, some devices cannot effectively separate fish eggs and fry, resulting in the destruction of un-hatched fish eggs by the first-hatched fry; the conveying pipe of some devices is prone to blockage, affecting the water flow and the adhesion of fish eggs. Therefore, the box for assisting in hatching fish eggs is proposed, which can effectively protect the fish eggs from being damaged during slow conveying by setting grooves and small holes on the top of the box to connect the conveying pipe and making the end of the conveying pipe smooth, solves the problem that the traditional conveying method may cause damage to the fish eggs, and provides good hatching conditions for the fish eggs by maintaining a suitable environment for the fish eggs in the box, which helps to improve the hatching rate of the fish eggs and the survival rate of the fry. The up-and-down movable punching baffle and the controllably opened two sides of the box can effectively distinguish between large and small fry and drive the small fry out of the box after they hatch and grow up, solving the problem of decreased hatching rate caused by the mixing of fry and fish eggs. SUMMARY
