AI Technical Summary
Existing brown scorpionfish fry rearing devices are prone to causing fry injury, uneven water temperature and dissolved oxygen distribution, easy pipe blockage, and large water flow disturbances, which affect the fry survival rate.
The system adopts a combination structure of exchange tube and annular airbag. The exchange tube has through holes arrayed on its side, and the annular airbag is divided into independent chambers. Together with filter plates and aeration components, it forms a stable water flow and air flow distribution, blocks fish fry from contacting the bottom pipe, and optimizes the water flow and dissolved oxygen distribution.
It improves the stability of the fish fry rearing environment, reduces the probability of fish fry injury, enhances the uniformity of dissolved oxygen in the water, reduces pipe blockage, and improves the survival rate of fish fry.
