Problems solved by technology

Existing fish harvesting devices usually have the following deficiencies: First, the harvesting operation is likely to disturb the fish school, resulting in difficulty in harvesting or insufficient number of harvests, requiring multiple harvests, which increases the difficulty of harvesting ; Second, the structure of existing harvesting devices usually only considers the ability to capture fish samples, without considering the damage caused to fish, nor considering the survival of fish

Abstract

The invention relates to a live fish catching device, comprising a first support ring, a second support ring and a third support ring from bottom to top. The bottom of the live fish catching device is sealed. The first support and the second support ring are enclosed through waterproof cloth. The second support ring and the third support ring are enclosed through netting. The third support ring is connected with a plurality of ropes. The live fish catching device comprises an inflatable balloon at the top. The second support ring is provided with a support structure for keeping the waterproof cloth open to form a water storage space after catching. The live fish catching device can provide a gentle catching process and facilitated catching, with less injury caused to fish bodies, dewatering of fishes is avoided during catching, and live fish catching is guaranteed accordingly.

Description

Technical field [0001] The invention belongs to the technical field of fish harvesting, and particularly relates to a live fish harvesting device. Background technique [0002] Fish sample measurement and tissue collection are one of the most commonly used and most basic technical methods such as fish breeding and disease research. In the process of fish investigation and research, sample collection is an important link. Existing fish harvesting devices usually have the following deficiencies: First, the harvesting operation is easy to disturb the fish school, causing difficulty in harvesting or insufficient harvesting, requiring multiple harvesting, which increases the difficulty of harvesting. ; Second, the existing harvesting device usually only considers the structure of the fish that can be caught, and does not consider the damage to the fish or the survival of the fish. Summary of the invention [0003] The technical problem to be solved by the present invention is to provi...
