Description

Technical Field

[0001] The utility model relates to the technical field of fry catching, in particular to a fry catching and screening device. Background Art

[0002] Fish fry, also known as fish flowers, are young fish that have been hatched not long ago, generally 6 to 9 mm in length. There are artificially bred fish fry and natural fish fry from rivers. During the breeding and cultivation process of fish fry, due to the different sizes of fish fry, the fish fry need to be roughly graded and then salvaged and released, but traditional fishing devices mostly use casting nets.

[0003] After searching, the application with patent number CN219981894U discloses a fry catching and screening device, including a screening device main body, and a fishing component installed on one side of the screening device main body. The fishing component includes a support plate rotatably connected to one end of the screening device main body, a winch installed above the screening device main body, and a fishing net arranged on one side of the screening device main body. In this way, the fry can be screened quickly, which is simple and convenient.

[0004] However, due to the arrangement of the fishing component and the steel cable, the length of the fishing component is fixed, and the screening device body is placed on the river bank. The distance from the fishing net to the screening device body is fixed, resulting in that fishing can only be carried out in fixed places. The sorting component is located at the lower side of the fishing net, resulting in that the fishing net cannot be completely sunk to the bottom of the water, and the bottom fish fry cannot be caught, resulting in poor fishing effect. At the same time, since the sorting component is located at the lower side of the fishing net, the fish fry can only be sorted on the water, which is inconvenient.

[0005] Therefore, we propose a fry catching and screening device. Utility Model Content
