Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an automatic fish grading and screening device. Background Art

[0002] Fish farming refers to the process of keeping fish in a breeding pond, and artificially raising fish by means of oxygenation, feeding, water change, water temperature control and water quality testing. The fish will be shipped after they grow to a certain size or weight. In the process of breeding, due to differences in feed feeding, fish diseases and physical fitness, the fish will grow in different sizes. In the long run, large fish will prey on small fish, resulting in a decrease in the overall survival rate and an increase in breeding costs. Therefore, in the process of fish breeding, it is necessary to regularly grade and screen the fish so that large fish and small fish can be separated for breeding. At present, most of the grading and screening methods are automated or semi-automated, and fish are graded and screened by vibrating screens. However, in the process of screening fish, staff still need to use scoop nets or bamboo poles to drive the fish so that the fish pass through the vibrating screen. The manual driving method can easily scare the fish and cause collisions and injuries. In addition, the current breeding industry is relatively developed, and the sizes of breeding ponds vary. It is impossible to select reasonable screening tools according to different sizes. The screening effect is not good, and the breeding cost will increase. Utility Model Content
