AI Technical Summary

Technical Problem

Existing fish fry release devices lack integrated oxygen supply systems, leading to a decrease in dissolved oxygen levels in the water during transportation and release. This results in fish fry suffering from hypoxia, surfacing, suffocation, and even mass mortality, increasing aquaculture costs and economic losses.

Method used

Design a fish fry release device with oxygen supply function, including a frame, fish box, drive unit and oxygen generator. Fish fry are released by flipping the fish box, and oxygen supply pipes continuously supply oxygen into the fish box to ensure the oxygen needs of the fish fry.

Benefits of technology

By providing continuous oxygen, the mortality rate of fish fry during transportation and release was reduced, the survival rate and growth performance of fish fry were improved, and economic losses were reduced.

Abstract

This utility model relates to the field of aquaculture technology, and in particular to a fish fry release device with oxygen supply function for aquaculture, including a frame and a fish box rotatably connected to the frame; a drive component for driving the fish box to flip is installed on the outside of the frame, and a locking component is also provided between the frame and the fish box; wherein, an oxygen generator is fixedly installed inside the frame, and an oxygen supply pipe is provided inside the fish box, the oxygen supply pipe being connected to the oxygen outlet pipe of the oxygen generator. In this utility model, the fish box is flipped by the drive component to realize the release of fish fry. The fish box adopts an open top and a tilted front design to facilitate the outward export of fish fry. This design allows for direct observation of the release situation during the release of fish fry. At the same time, the configured oxygen generator can continuously supply oxygen to the inside of the fish box, thus ensuring the oxygen supply needs of the fish fry during transportation and release, thereby reducing the occurrence of fish fry mortality.
