Further, the fish luring lamp 5 adopts light lengths with different colors to stimulate the fishes.
In the using method of the automatic grading device for the live fish in the aquaculture water body, the blocking net 6 is in a multi-section foldable and detachable mode, the grading grid device is fixed and fixed in a net folding stage, the fish luring lamp 5 is turned on, fish are lured to pass through the grids in a shuttling mode, the blocking net is moved slowly to drive the fish, and in the net folding stage, the blocking net 6 is folded inwards; thereby being suitable for grading fish ponds with different sizes.
The invention has the beneficial effects that:
1) the grading efficiency of the fishes is improved;
2) the spacing is flexible and adjustable, and the fish can achieve good grading effect without dehydration in the grading process;
3) the operation and the use are convenient, and the whole grading operation can be completed by one person under normal conditions.
4) The poking wheel is detachable, and the size of the grating is reduced.
5) In the process of changing the distance between the grids, gaps at two ends are separated by fishing nets, so that grading errors are reduced.
6) The detachable lamp stimulates the fishes by adopting light lengths with different colors, so that the grading efficiency is improved;
7) the grid material chooses transparent ya keli cover outside the rod iron for use to promote classification efficiency.
8) The blocking net is composed of a plurality of units which are connected in a rotating mode, can be applied to fish ponds of different specifications, and is high in applicability and universality.
