Fish gathering and transferring system for improving fish passing efficiency

Abstract

The invention relates to a fish gathering and transferring system for improving fish passing efficiency. The system comprises a fish gathering platform, a deep-water net foil, a transfer working platform, a fish gathering tank, a live fish temporary-breeding tank and a fish gathering platform anchoring device, the fish gathering platform anchoring device is connected with the fish gathering platform, the deep-water net foil comprises an in-shore net foil belt, an offshore net foil belt, an in-shore blocking net and an offshore blocking net, the in-shore blocking net is connected with the in-shore net foil belt, the offshore blocking net is connected with the offshore net foil belt, the in-shore blocking net and the offshore blocking net are opposite and in asymmetric arrangement, the in-shore net foil belt and the offshore net foil belt are parallel and form a fish passing channel, multiple net doors are arranged in the fish passing channel, and height of the net doors is sequentiallyincreased along the advancing direction of fish school; a fish taking portion is arranged at the tail end of the fish passing channel, the upper surface of the fish taking portion is flush with that of the fish gathering platform, and the fish gathering tank is arranged on the fish gathering platform and collects the fish school from the fish taking portion. The fish gathering and transferring system has the advantages of high fish gathering efficiency, reliable safety and easiness in operation.

Description

technical field [0001] The invention belongs to the technical field of fishery and relates to a system for collecting and transporting fish, in particular to a system for collecting and transporting fish for improving the efficiency of passing fish. Background technique [0002] In order to meet the needs of fish crossing dams, the measures taken at home and abroad are mainly divided into three categories: the first category is the construction of fish passing facilities, mainly including fishways, fish gates, fish elevators, etc.; the second category is building artificial simulation Spawning ground; the third category is to carry out artificial breeding and release. At present, our country is vigorously developing fish passing facilities, but due to its high construction cost, high design difficulty, difficult operation and management, and large differences in fish passing effects for fish with different ecological habits, the development of fishway construction is slow. ...

Problems solved by technology

[0004] Publication No. CN102524146A discloses a fish trapping device for marine pastures, which mainly uses sound control to trap fish. The disadvantage is that the device structure is relatively complicated, and it is only suitable for ocean waters and the entire process of use. The device can only float on the water surface, not suitable for the induction of bottom fish

[0005] In the publication number CN103070097A, an artificial fish gathering protection device is disclosed. Although the device is simple in structure and easy to use, it has certain limitations in the use process, and the fish trapping effect is not very obvious, and the scope of application is small
