AI Technical Summary

Technical Problem

Existing technologies are time-consuming and labor-intensive when multiple people are involved in fish stocking operations, and they can cause significant harm to the fish, making it difficult to achieve safe and efficient stocking operations.

Method used

Design a multi-person fish breeding and release device, including a fish tank and a temporary holding tank, made of transparent acrylic sheet. The fish are released without damage by magnetic attraction between the movable door panel and the galvanized pipe. Combined with the box support and inclined design, it ensures that the fish do not leave the water during the release process.

Benefits of technology

It enables time-saving and labor-saving release operations, ensures that fish stay in the water throughout the process, improves the safety and efficiency of release, and supports simultaneous operation by multiple people.

Abstract

This invention provides a multi-person operated fish stocking and release device, constructed from a stainless steel frame and transparent acrylic sheet. It includes a fish-adding trough and a holding trough. Three fish-adding troughs are provided, two connected to the ends of the holding trough and the third connected to the middle. The holding trough has several fish outlets along its length, each closed by a movable door. During fish release, the operator only needs to open and close the movable door to complete the operation. The fish-adding troughs at both ends and the middle of the holding trough ensure even distribution of fish. The fish in the holding trough are released through the movable door, ensuring the fish remain in the water throughout the release process, guaranteeing the safety of the released species, and saving time and effort.
