Folding net frame for aquaculture fish fry

Abstract

The invention relates to a folded net frame for aquaculture, in particular to a folded net frame for temporarily raising fish fry in aquaculture. The technical problem of the present invention is to provide a folded net frame for temporarily raising fish fry in aquaculture and preventing fish fry from swimming out. The technical embodiment of the present invention is: a kind of aquaculture fry temporarily raises the folded net frame, comprises the first support plate, the second support plate, the third support plate etc.; The second support plate, the left side of the second support plate is connected to the third support plate in a rotational manner, and the fourth support plate is rotationally connected between the front and rear two third support plates, and the connection between the second support plate and the third support plate Equipped with a fixed mechanism. The floating mat of the present invention has buoyancy, which can make the present invention float on the water surface, so that the fishing net can be placed in the water, which is convenient for temporarily raising fry, and the fishing net can be hung on the hook to prevent the fry from swimming out, and the floating mat can be adjusted by making the hollow rod tilt upward When the water level in the breeding pond is low, the fishing net cannot enter the water.

Description

technical field [0001] The invention relates to a folded net frame for aquaculture, in particular to a folded net frame for temporarily raising fish fry in aquaculture. Background technique [0002] Immediately after hatching, the fish fry are sent to the breeding pond for direct stocking, which is very easy to be infected with pathogenic bacteria and cause diseases; and the fish fry just hatched are not yet adapted to the environment, and they tend to be alone in a corner without activities, which will affect their future foraging and adaptation. After a period of time, the fish fry will be stocked intensively after a period of time. At present, the farmers usually use a pole to stand on a corner of the breeding pond and then fix the fishing net on the pole, and then put the fish fry into the fishing net for temporary breeding. But the pole is easy to topple under the action of water, so that fry are easy to swim out from the fishing net. Contents of the invention [000...
