AI Technical Summary
Existing technologies for hatching grouper sinking fish eggs suffer from problems such as poor seawater flow and mechanical agitation damaging egg cells, resulting in low hatching rates and susceptibility to bacterial and viral infections.
A grouper sinking fish egg incubation device was designed, which uses a transparent incubation tank and incubation rack. The bottom of the incubation box is open. A wave pump simulates the marine environment. Seawater enters the incubation box from below and turns the fish eggs. Seawater containing nutrients and disease-resistant drugs can also be prepared. The incubation box is surrounded by a mesh to enhance transparency and facilitate observation.
It improved the hatching success rate of grouper sinking fish eggs, reduced mechanical damage, enhanced the protection of fish eggs, and improved hatching rate and health.

TECHNICAL FIELD
[0001] The utility model relates to the field of fish egg hatching, especially a goby sinking fish egg hatching device. BACKGROUND
[0002] Goby is a kind of seawater fish with economic benefits, and at present, its cultivation is mainly artificial pond culture. However, in the process of cultivation, if the cultivation environment is not well controlled or the fish egg yield is large, sinking fish eggs are likely to occur, and if the sinking fish eggs are not intervened, it will cause the death of fish eggs and economic losses. Therefore, the early sinking fish eggs need to be doubly protected, including isolated hatching to fully contact fresh seawater to fully absorb oxygen and nutrients, and isolated hatching to reduce the invasion of bacteria and viruses or to prepare suitable disease-resistant nutrient solution, so as to improve the hatching rate. However, the common practice in the field at present is to discard the sinking fish eggs after screening, and there is no measure and device for rescuing the sinking fish eggs. In the existing hatching device specially used for sinking fish eggs, the upper and lower stacking of the egg laying area is relatively compact, so that seawater mainly enters from the side, or the mechanical turning of fish eggs may cause further damage to the fragile fish eggs, and it is not suitable for the sinking fish eggs of goby.
