A kind of pointed pen cap screw light lure trawl net

Abstract

The invention discloses a pointed pen cap screw light lure trawl, comprising: a frame and a net body; a net body is connected to one side of the frame, and a first chute and a second chute are arranged on the inner side of the frame, the first chute A number of first light source parts are matched and connected inside the chute, and a number of the first light source parts can move along the first chute, and a number of second light source parts are matched and connected inside the second chute. The second light source part can move along the second chute; the frame is a square ring-shaped structure, and traction grooves are arranged on each side on one side of the frame, and the traction grooves on the symmetrical sides are dislocated and distributed, The inner side of the traction groove is matched with a traction rod, and the free end of the traction rod is connected with a traction rope.

Description

technical field [0001] The invention relates to a fishing trawling net, in particular to a sharp-pointed cap screw light lure trawling net. Background technique [0002] Trawling is a fishing operation method in which a fishing boat is used to drag a sack-shaped net to force the fishing object into the net. The pointed snails belong to the gastropoda, the subclass of the subclass, the pteropods, the snail family, and the snail. As for the risks or adverse effects caused by the outbreak of the cap 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 mollusk cap snails broke out, and the phenomenon of group aggregation was significant, and a large number of them drifted on the shore. The large outbreak of thorn snails may be related to the proliferation and high aggregation of phytoplankton, protozoa or bacteria in seawater. According to the structural characte...

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
