An aquaculture dead fish fisher

Abstract

The invention relates to an aquaculture dead fish fishing device, in particular to an aquaculture dead fish fishing device. The technical problem of the invention is to provide an aquaculture dead fish fishing device capable of reducing water flow fluctuation, improving fishing efficiency and saving time. The aquaculture dead fish fishing device comprises a support tube, a first directional wheel,second directional wheels, an N-shaped tube, third directional wheels, pulling ropes, iron needles, fixing plates, first springs, fourth directional wheels, etc. The first directional wheel is connected to the left part of the rear side surface in the support tube, the two second directional wheels are connected to the rear side surface in the support tube on the lower side of the first directional wheel, and the N-shaped tube is connected to the bottom of the support tube. As a hollow handle moves to the right, the two fixing plates can be pulled together by the pulling ropes, the first spring sheets is compressed, and the two fixing plates can be pulled together to drive the iron needles to be inserted into the body of the dead fish, so that the body of the dead fish can be fixed.

Description

technical field [0001] The invention relates to a catcher for dead fish in aquaculture, in particular to a catcher for dead fish in aquaculture. Background technique [0002] The decay of dead fish needs to consume oxygen in the water. If the number is too large, the dissolved oxygen will decrease, which will affect the survival of other live fish. Therefore, it is necessary to salvage the dead fish after death. When the existing dead fish are salvaged, the boat is usually manually driven. , and use a hand-held fishing net to salvage the dead fish. When the boat is in use, the water flow will fluctuate, so the dead fish will easily sink, and it will take a long time for the dead fish to float on the water surface, which will reduce the number of dead fish The fishing efficiency is high, and it takes a long time. In order to improve the efficiency of dead fish fishing, the fishing net will be tied to a longer wooden stick manually, and then the dead fish will be fished manual...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of manually driving a small boat and using a hand-held fishing net to salvage dead fish, the water flow will fluctuate and the dead fish will easily sink, which will reduce the fishing efficiency of the dead fish and take a long time, the technical problem of the present invention Yes: Provides an aquaculture dead fish catcher that mitigates water flow fluctuations, improves catch efficiency and saves time
