Technical Field

[0001] This utility model relates to the field of juvenile fish farming technology, and in particular to an integrated device for grading, screening and feeding juvenile fish. Background Technology

[0002] In aquaculture, juvenile fish generally need to be raised individually. Traditional feeding methods usually involve manually placing feed, which is not only inefficient but also increases the workload of staff.

[0003] Currently, automatic feeding equipment is used for feeding. Existing automatic feeding equipment is generally equipped with a discharge nozzle and a mechanism that makes the feed roll in the storage box. With the help of sensors and controllers, it can realize the timed and fixed-time feeding of feed, reducing the expenditure of labor costs.

[0004] However, using the above method, with the cooperation of sensors and controllers, the feed in the storage box is discharged into the rearing pond through the discharge nozzle, realizing timed and fixed-time feeding and reducing labor costs. However, during the entire rearing process, only simple feeding can be carried out, and it is not possible to temporarily house juvenile fish of different sizes separately, thus affecting the uniformity of juvenile fish growth. Utility Model Content
