The utility model discloses a device for
hatching, separating and collecting fertilized eggs of diptychus maculatus and newly hatched larvae, which comprises a
hatching assembly used for
hatching the fertilized eggs of the diptychus maculatus. The first water pump
assembly is used for forming upward
water flow above the fertilized eggs in the hatching
assembly and creating a still water or micro-flowing
water environment for the fertilized eggs at the same time; the two ends of the flow guide groove are connected with the hatching assembly and the separation and collection assembly respectively, and after the fertilized eggs are hatched into newly hatched larvae, the newly hatched larvae enter the separation and collection assembly through the flow guide groove; the separating and collecting assembly is used for collecting newly hatched fry; the second water pump assembly is used for conveying the
aquaculture water to the separating and collecting assembly. The device is used for large-
scale separation of fertilized eggs and newly hatched fries, collection of floating fries is considered, the hatching rate of the fertilized eggs and the
survival rate of the newly hatched fries can be effectively improved, and the risk that the fertilized eggs and the newly hatched fries are infected by pathogenic microorganisms such as water
mildew and ichthyophthirius multifiliis is reduced. In addition, fertilized eggs and newly hatched
larva fishes which stop developing and are attached to the hatching plates in the hatching box are cleaned by adding the attaching plates, and the hatching success rate is effectively increased.
