Description

Multi-variety fish layered collection system

Technical Field

The application relates to the technical field of fishery fishing, in particular to a layered collection system for multiple varieties of fishes.

Background

At present, deep water fishing is generally carried out in a net cage arranged at sea, the offshore net cage culture in China is mainly concentrated in shallow and near sea areas within 20m of the equal-depth line, and the offshore culture adopts a gravity net cage with a size of hundreds of cubic meters to thousands of cubic meters. Due to the problems of land pollution and overlarge culture density, the offshore cage culture is easy to cause frequent culture diseases, ecological environment deterioration and the like, so that the space available for mariculture in the offshore sea area is severely extruded based on the development of economy and society and the requirements of ecological environment protection. In order to realize the green development of the modern mariculture industry in China and reduce the influence of culture on coastal areas, the cage culture is gradually advanced from offshore to open sea, so that the wide deep and open sea culture sea area is expanded.

The existing fishing device generally uses a fishing net scattering mode, then the net is collected to form a closed space, aquatic fishes in the net can be caught, in the process of scattering the fishing net to the collecting fishing net, part of fishes can actually run out from an opening of the fishing net, the fishing efficiency is low, the caught fishes are difficult to run out from the fishing net if the body type of the caught fishes is slightly larger than the holes of the fishing net, the small fishes are caught, and the large-size fishes and the small-size fishes are difficult to distinguish.

Along with the progress of technology, the related art technicians also optimize the device for capturing the deep water fishery, for more accurate comparison, for example, chinese patent publication No. CN217089210U discloses a fish induction capturing device comprising a traction structure, a capturing frame, a first capturing net, a second capturing net, and the like; when the fish catching device is used, the fish is attracted by the trapping lamp, meanwhile, the feed is sprayed out through the feed supply structure, when fish enters from the fish inlet frame, the fish can only enter the fish catching frame and cannot come out due to the unidirectional fish inlet structure, the effect of trapping the fish is achieved, after the fish enters, the effect of classifying the fish is achieved due to the arrangement of the two fishing nets with different diameters, and meanwhile, the effect of automatically placing small-sized fish fries is achieved by utilizing meshes formed in the fishing frame.

However, when the above prior art is used for fishing deep water fish, there are also the following problems: 1. although the device can screen fishes with different volumes entering the fishing frame, an effective means cannot be adopted to drive the fishes with smaller volumes in the fishing frame to pass through the first fishing net and the second fishing net in sequence so as to be screened.

2. The device adopts the feed pump to attract the fish shoal and pacify the fish in a feed spraying mode, so that the cost consumption of fishing is greatly increased, and the feed sprayed into water can be mixed with water to pollute the water quality to a certain extent if the feed is not consumed by the fish shoal, so that the environment of subsequent fish fry breeding is affected.
