AI Technical Summary

Technical Problem

In existing technologies, it is difficult for marine aquaculture vessels to achieve large-capacity, shape-preserving, and rapid release of fish fry in cage designs, and traditional hanging bags have small capacity and are prone to damaging fish fry.

Method used

A fish fry transfer cage for marine aquaculture was designed, including a net, netting, flexible bag, float, rope retrieval mechanism, and LED light fish-attracting system. The cage can be opened and closed quickly by controlling the rope retrieval and the inflation and deflation of the float, ensuring the safe transfer and rapid release of fish fry.

Benefits of technology

It enables large-capacity fish fry transfer, protects the fish fry from damage, improves transfer efficiency, and ensures smooth entry and exit and rapid release of fish fry.

Abstract

The application discloses a fish fry transfer cage for offshore aquaculture and belongs to the technical field of aquaculture. The fish fry transfer cage comprises a net, a mesh, a flexible bag, a floating body, a rope winding and unwinding mechanism and a rope. The net is provided with an opening on the side surface and is used for structural support of the whole transfer cage. The flexible bag is connected and arranged in the net and is provided with an opening. The opening is located between the upper edge of the mesh and the upper edge of the opening of the net. Through the application, the opening of the net can be quickly opened and closed by controlling the winding and unwinding of the rope, so that the fish fry transfer is smoothly carried out. The net provides structural support for the flexible bag and protects the shape of the flexible bag. The design of the flexible bag can protect the fish fry from being damaged. The floating body arranged on the other side of the net can help the net to be inclined, so that the fish fry is smoothly and quickly poured out from the opening of the flexible bag, the fish fry is quickly poured into the tank, the transfer efficiency is improved, and the application has the advantages of simple structure, convenient use, high efficiency and the like.
