Creseis acicula light-induced trawl net

Abstract

The invention discloses a creseis acicula light-induced trawl net. The trawl net comprises a frame and a net body, the net body is connected to one side of the frame, a first sliding groove and a second sliding groove are formed in the inner side of the frame, a plurality of first light source parts are connected into the first sliding groove in a matched mode and can move along the first sliding groove, and a plurality of second light source parts are connected into the second sliding groove in a matched mode, and can move along the second sliding groove. The frame is of a square annular structure, traction grooves are formed in all edges located on one side of the frame, the traction grooves located on the symmetrical edges are distributed in a staggered mode, traction rods are connected to the inner sides of the traction grooves in a matched mode, the free ends of the traction rods are connected with traction ropes, and the traction ropes on the traction rods located on the symmetrical edges of the frame are gathered at one point. The traction rods can slide along the traction grooves.

Description

technical field [0001] The invention relates to a fishing trawl, in particular to a sharp pen cap screw light lure trawl. Background technique [0002] Trawl fishing is a fishing operation method in which a fishing boat drags a bag-shaped net gear to force the fishing target into the net. The snails belong to the gastropods, postbranchia, pteropods, snails, and snails. With regard to the risks or adverse effects caused by the outbreak of snails, the ecological disasters that may be caused by the outbreak, and the impact on the safety of surrounding institutions and facilities, a large number of planktonic molluscs, such as snails, have erupted in large numbers, and the phenomenon of group gathering is obvious, and a large number of them drift on the shore. The large number of outbreaks of snails may be related to the proliferation and high accumulation of phytoplankton, protozoa or bacteria in seawater. Trawls can be divided into sleeved trawls and sleeveless trawls accordin...

Problems solved by technology

[0003] The traditional trawl for fishing snails is used to drag the trawl to the stern of the fishing boat through the traction rope. When the fishing boat changes direction or the water flow changes direction, it is easy to cause knots on several traction ropes. The traditional trawl for fishing snails is only through The fishing boat is towed, and the snails are collected into the fishing trawl through the impact of the water flow. However, the snails cannot be gathered during the movement of the fishing boat. The existing fishing trawls do not have lights near the frame of the fishing trawl to induce them, so the fishing effect is relatively low. Difference
