Disabled and dead fish collector for aquaculture

Abstract

The invention provides a disabled and dead fish collector for aquaculture. The disabled and dead fish collector comprises a fishing net, a crusher, a pulverizer, a high-temperature drying box, a firststorage bucket, a second storage bucket, a protective cover, a battery and a motor. A boat groove, a first storage groove and a second storage groove are formed in the end surface of the top of a boat body, two fishing rods are arranged at the front end of the end surface of the top of the boat body, and eight sliding holes are formed in the right ends of the fishing rods to facilitate the capture of disabled and dead fish, so that the situation that the harmful bacteria contained in the disabled and dead fish pollute the aquaculture water and cause damage to the fish within the aquaculture water is avoided. Unlike other exiting fishing devices prone to escape of wounded fish when used, the collector effectively avoids the escape of the wounded fish and improves the efficiency of water cleaning by trapping the wounded fish inside a spherical structure composed of eight grab bars and the fishing net.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a disabled and dead fish collector for aquaculture. Background technique [0002] Dead fish are unavoidable in aquaculture, but in the circulating aquaculture system, due to the high breeding density and low water exchange rate, the color of the water body is dark, and the dead fish will float on the water surface, causing great pollution to the water body. If the treatment is carried out, a large number of harmful substances such as bacteria will grow inside the fish body, and it will also affect the fish body that affects the health, resulting in a reduction in breeding production. [0003] Based on the above, the inventors have found that the existing one-way fishing device as mentioned in the Chinese invention such as application number 201010124045.1 includes a hoop, a rotating shaft, a blocking net, a handle, a non-return strip, a net cover and torsion spri...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the above-mentioned technical problems, the present invention provides a disabled dead fish collector for aquaculture to solve the problem that the fish body cannot be processed later, which is easy to cause environmental pollution, and the harmful bacteria inside the fish body are easy to affect the work. The damage caused by personnel, the ability to collect wounded fish and residual fish with weak feeding ability is weak, and the fish body can only be caught by the fish body biting the hook. Water pollution, a problem that harms otherwise healthy fish populations
