This integrated fish fry hatching device adopts high-transparent acrylic hatching barrels, allowing intuitive observation of fish egg development and fry activity status. The complete machine is integrated with a base, circulating water pump and a full set of PVC pipelines and valves. Five groups of hatching barrels work in parallel to realize centralized fry hatching and breeding. The slow rising water flow agitates the water body to simulate the natural water environment, reduce fish egg accumulation, and effectively improve the survival rate of hatched fry. All pipelines of the equipment are equipped with control ball valves to independently adjust the inlet water flow of each hatching barrel. The base is made of sturdy and corrosion-resistant PP material, which is suitable for indoor recirculating aquaculture workshops. It is applicable to the hatching and breeding of various freshwater and marine fish species, with customizable specifications to meet customers' diverse needs.
