AI Technical Summary
The existing hatching tanks are not stratified, which makes it easy for sticky eggs and fry to stick together or settle at the bottom and die from lack of oxygen.
A multi-layered hatchery was designed, employing a wire mesh frame and water control structure. Water circulation is achieved through a water pump and return pipe, reducing hatching density and preventing the settling of sticky eggs and fry. Combined with temperature control and oxygen supply, the hatching effect is improved.
This method enables layered hatching of sticky egg fry, reducing hatching density, avoiding accumulation and oxygen deficiency, and improving hatching success rate.
