Description
Technical Field
[0001] The utility model belongs to the technical field of fry breeding, and particularly relates to a fry density control device for fry breeding. Background Art
[0002] In fry breeding, generally, multiple types of fry are raised in a breeding pond through a feeding box. On the one hand, it saves breeding space. On the other hand, it promotes the interaction and contact among multiple types of fry, simulates the final growth environment of the fry, and at the same time ensures that various plankton in the breeding pond are fully preyed on by the fry, saving the feeding cost.
[0003] During the existing fry breeding period, most of the time, multiple types of fry are mixed and raised together. If the sizes of the fish groups cannot be separated in the early stage, the phenomenon of big fish eating small fish in one pond will occur, thus reducing the survival rate. For this reason, we propose a fry density control device for fry breeding. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fry density control device for fry breeding, so as to solve the problem that the phenomenon of big fish eating small fish in one pond occurs during fry breeding as mentioned in the above background art.
