lifting fishing net

Abstract

The invention relates to a lifting fishing net. The lifting fishing net comprises a fishing net rope, a fishing net fall, a fishing net buoy and a light source module, wherein the fishing net fall and the fishing net buoy are respectively arranged at the bottom and the top of the fishing net rope, the light source module is arranged on the fishing net buoy, a net fall part comprises a net fall body, a rotary knob and counter weight filling particles, the net fall body is hollow in structure, a rotary knob hole is formed in the side wall of the net fall body, the rotary knob is connected with the rotary knob hole by virtue of a screw thread, and the counter weight filling particles are contained inside the net fall body. The lifting fishing net can adjust length of an adjustment lifting line between a lifting buoy and a fixed buoy, the adjustment lifting line can limit the fishing net rope to stay in a corresponding deep water region with more fishes, scientific fishing can be better carried out according to water depth gradients of the fishes, and fishing efficiency is relatively high.

Description

Technical field [0001] The invention relates to the technical field of fishery resource fishing, in particular to a lifting fishing net. Background technique [0002] At present, in areas with rich terrestrial fishery resources, such as natural lakes, reservoirs, and rivers, especially when the depth of the water is large, the distribution of the water depth gradient of fish is more obvious, for example, herring is inactive. It usually lives in the middle and lower layers of water. The main food is snails, mussels, clams, clams, etc. It also preys on shrimp and insect larvae. For example, grass carp, also known as grass carp, feeds on grass and inhabits the middle and lower layers of water. The pelagic fish of the genus silver carp feeds on plankton throughout their lives. Another example is that bighead carp likes to live in still water. The pelagic fish feeds on zooplankton and some algae. For example, the white-striped fish has a lively habit to float in the upper layer of the...

Problems solved by technology

[0004] However, the existing fishing nets generally include sinking nets and floating nets. Due to the limitations of the existing fishing net structure, they generally either sink directly to the bottom of the water or float on the water surface. Scientific fishing is carried out according to the water depth gradient distribution of fish, and the fishing efficiency is low
