The puffer green has excellent culture characteristics, is easy to domesticate and culture in omnipotent, and is suitable for various culture modes such as factory workshop culture, pond culture, cage culture and the like; when the net cage is used for cultivation, the net can be cleaned, and the labor cost is reduced; the commodity specification is various, and 150g can be sold. The puffer green meat is compact, the freeze processing technology is mature, the puffer green meat is suitable for long-distance transportation and long-time preservation, and the cultivation income is stable.
At present, fertilized eggs of the puffer green are mainly obtained by adopting a natural spawning mode in the breeding production, are sticky and sinking, are often adhered with a large amount of impurities such as parent fish feces on the surfaces of parent fish ponds, and are easy to breed germs after being transferred into the breeding ponds. In addition, fertilized eggs and unfertilized eggs are often gathered together due to viscosity, are not easy to separate, and the rotten of unfertilized eggs can aggravate germ reproduction in a seedling raising pond and influence seed cultivation. Although the existing method for debonding and separating the fertilized eggs of the puffer fish is adopted, the two procedures are separated from each other and require more manual operation, and are time-consuming and labor-consuming; in addition, frequent manual operations are prone to damage to fertilized eggs, affecting the subsequent hatching process. Therefore, development of the oosperm disbonding, separating and hatching integrated device and method is very important for improving the oosperm hatching operation efficiency of the puffer green and reducing the labor cost

3. Separating: taking out the air stone, standing for 5 minutes, separating fertilized eggs and unfertilized eggs with different specific weights by using a high-salt solution, floating the fertilized eggs on the surface, and sinking the unfertilized eggs on the bottom of the barrel; opening a lower water outlet switch, discharging half of water in the barrel, and discharging unfertilized eggs;
4. hatching: closing the lower water outlet, opening the upper water outlet, allowing water to enter the water inlet, putting an air stone into the water inlet, putting the air stone into the position of the lower water outlet, and inflating the air stone appropriately to form soft ascending water flow in the barrel, so as to push fertilized eggs sunk into the bottom to float again;
5. collecting fertilized eggs: continuously observing the embryo development progress of fertilized eggs, and collecting fertilized eggs at a lower water outlet when the embryo body is found to have muscle effect and heartbeat.
Compared with the prior art, the utility model has the beneficial effects that:
1. labor is saved: in the prior art, in the step of debonding and separating, the fertilized eggs are required to be mixed with debonding liquid and separating liquid manually, and the fertilized eggs are required to be collected manually by using a screen after debonding and separating, so that the operation is complicated. The utility model provides a device for separating fertilized eggs by de-adhesion, which only needs to add corresponding reagents to prepare de-mucilage and separation liquid, and after the fertilized eggs are put into the device, the device is inflated, and water flow generated by gas is utilized to mix the fertilized eggs uniformly; and then after a short time of standing, opening a lower water outlet to discharge unfertilized eggs, thus completing the step of debonding and separating, and having simple and convenient manual operation.
