Live fish transfer device for relay culture of larimichthys crocea

Abstract

The invention relates to the technical field of fishery breeding, in particular to a live fish transfer device for relay culture of larimichthys crocea, which comprises a high-position lifting assembly and a low-position lifting assembly. The high-position lifting assembly and the low-position lifting assembly are respectively mounted on two sides of a ship body, and the high-position lifting assembly is connected with the low-position lifting assembly through a fishing net. According to the device, the fishing net is sunk into the bottom of a fishpond in a contracted state through a lifting mechanism, the fishing net is expanded from the bottom of the fishpond through a simple net expanding assembly, then the height difference between the two sides of the fishing net is manufactured after the fishing net is lifted, fishes can slide into sliding ways along the fishing net to enter a aquaculture net cage in a tensioned state of the fishing net, mutual extrusion between the fishes is reduced, live fish loss caused by extrusion is effectively reduced, operation procedures are reduced, the workload of a user is relieved, and a large amount of time is saved for the user.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a live fish transfer device for relay farming of large yellow croakers. Background technique [0002] In the process of relay breeding of large yellow croaker, it is necessary to transfer the large yellow croaker from the breeding sea area to the live fish transport ship to the breeding cage in the suitable sea area. In the process of transferring large yellow croaker from the live fish transport ship to the culture cage, a specific device is required for the transfer operation. The previous operation tools or methods are time-consuming and laborious, and the design of the device is unreasonable, which causes the live fish to squeeze each other. The damage is serious. Contents of the invention [0003] The purpose of the present invention is to provide a live fish transfer device for relay culture of large yellow croaker, to solve the problems raised in the above-mentione...
