| description | The utility model relates to aquaculture equipment, particularly to a fry hatching device. The fry hatching device comprises filtering ponds and a hatching pond which are communicated with a water source and further comprises a drainage tank, the drainage tank is arranged inside the hatching pond, is closed at the periphery and is opened at the upper end, the height of the drainage tank is smaller than that of the hatching pond, and drainage exists which are communicated with a drainage pipe are formed inside the drainage tank; a hatching circuit is formed between the drainage tank and the hatching pond, and the bottom of the hatching circuit is connected with the filtering ponds through a water inlet pipe; a roe blocking net is fixed onto the upper end surface of the drainage tank, and the roe blocking net and the upper end surface of the drainage tank form a vertical angle. By means of the above structure, when the water level inside the hatching circuit reaches the upper end of the drainage tank, the roe b |
