Aquaculture fry temporary culture folding net frame

Abstract

The invention relates to an aquaculture folding net frame, in particular to an aquaculture fry temporary holding folding net frame. The technical purpose is to provide the aquaculture fry temporary culture folding net frame which can facilitate the temporary cultureof the fry and prevent the fry from swimming out. The aquaculture folding net framecomprises a first support plate,second support plates,third support plates and the like; the front and rear sides of the first support plate are rotatably connected the second support plates, the left sides of the second support platesare rotatably connected to the third support plates, a fourth support plate is rotatably connected between the front and rear third support plates, and the connecting portions of the second support plates and the third support plates are connected with fixing mechanisms. A floating mat has buoyancy, and can make the frame float on a water surfaceso that the fishing net can be located in the water, which providesconvenience for temporary culture of the fry, the fishing net hangs onhooksto prevent the fry from swimming out, a hollow rod can be tilted upward to adjust the height of the floating mat, and it is avoided that the fishing net cannot enter the water when the water level in a culture pond is low.

Description

Technical field [0001] The invention relates to a folding net frame for aquaculture, in particular to a folding net frame for temporarily raising aquaculture fry. Background technique [0002] After hatching, the fry are sent to the breeding pond for direct stocking, which are highly susceptible to pathogenic bacteria and cause diseases; and the fry are not adapted to the environment after they are hatched, and they are easy to be alone and inactive, which affects future foraging and adaptation. The fry are intensively reared for a period of time before being stocked in a concentrated manner. At present, the cultivators generally 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 fry into the fishing net for temporary rearing. However, the pole is easy to fall under the action of water, and the fry are easy to swim out of the fishing net. Summary of the invention [0003] In order to overcome the shortcomings of using a...

AI Technical Summary

Problems solved by technology

[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 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. However, under the action of water, the pole is easy to fall, so that the fry can easily swim out of the fishing net
