Abstract

The invention relates to a squid fishing method using the principle of phototaxis of marine organisms. The method comprises the following steps of searching for a fishery, and determining the positionof the fishery before nightfall; according to the flow direction and conditions of ocean currents, dropping a parachute type anchor to fix a squid fishing boat; through a winch on the squid fishing boat, dropping an underwater fishing lamp with a steel ring protecting cover into a depth of 200-300 meters, then switching on the underwater fishing lamp to attract squid shoals; at night, switching on overwater fishing lamps which are provided with reflectors and distributed on both sides of the squid fishing boat; pulling the underwater fishing lamp up to a depth of 50-100 meters in water through a connecting rope; temporally mounting movable pulley devices on both sides of the squid fishing boat; through the movable pulley devices, dropping down special squid fishing lines with the bottom ends with squid fishing tackles for squid fishing operations. The squid fishing method using the principle of phototaxis of the marine organisms has the advantage of saving energy and labor and improves the fishing efficiency.

Description

technical field [0001] The invention belongs to the technical field of squid fishing, in particular to a squid fishing method utilizing the principle of phototaxis of marine organisms. Background technique [0002] Squid belongs to marine cephalopods. According to the analysis of the world's authoritative fishery experts, the total reserves of cephalopod resources in the global ocean are 50 million to 100 million tons, and the current global annual catch is about 3.6 million tons, of which about 70% It's squid. Squid is an annual fish. If the catch is too low, it is a waste. If the catch is too large, it may also cause the break of the food chain of marine organisms. It needs to be moderate and appropriate. In the ocean, squid is a pelagic fish with a long migration route and a wide migration sea area. The suitable production temperature is 6-20°C, and it swims at a depth of about 300 meters below sea level. [0003] Squid fishing is to use the phototaxis of squid to put a...
