Description

Aquaculture device

Technical Field

The invention belongs to the technical field of aquaculture, and relates to an aquaculture device.

Background

The sea cage culture is an important mode of aquaculture, aquatic products such as fish, shrimps, crabs and shellfish can be cultured in the cage, but most of the current cages are cylindrical and are fixed in seawater through anchoring equipment, and the upper ends of the cages are open, so that feeds can be fed conveniently. And the other net cages are closed net cages, and the small organisms or microorganisms naturally flowing into the net cages in seawater are used as nutrition for the organisms in the net cages to eat.

The closed net cages usually rely on small organisms or microorganisms naturally flowing into the net cages in seawater as nutrients for the organisms in the net cages to eat. The net cage has long service life, and marine organisms can be attached to the surface of the net cage, so that the net holes are blocked, the communication between the water inside and outside the net cage is not facilitated, the organisms entering the net cage are reduced, and the water quality in the net cage is deteriorated even if the biological excrement in the net cage is taken away by seawater.

Disclosure of Invention
