Zusammenfassung: | The invention relates to the field of fish egg screening, in particular to a finless eel fertilized egg hatching, forming and screening device. The technical problems that in the prior art, when ricefield eel fertilized eggs are hatched, the middle portions cannot be turned over, the fertilized eggs are necrotic due to oxygen deficit, meanwhile, the water temperature cannot be effectively controlled, the hatching rate of the fertilized eggs is reduced, and the fertilized eggs are prone to damage and low in selection efficiency in the manual selection process are solved. According to the technical scheme, the finless eel fertilized egg hatching, forming and screening device comprises a fixing frame, a water storage barrel and the like; a water storage barrel is mounted on the fixing frame; a heating pipe used for controlling the temperature of hatching water is arranged in the water storage barrel. According to the device, the semicircular metal sheets are upwards extruded through the aeration pipe, so that th |
