Trap Gillnet Fishing Device

Abstract

The invention discloses a trap type gillnet fishing device, and aims to provide a trap type gillnet fishing device which can effectively improve the fishing efficiency of a drift gillnet. It includes two fishing boats, one of which is equipped with a gill net lifting machine; a trapping device, which includes a bait attachment rope, a one-to-one corresponding bait storage tank arranged on the deck of the fishing boat, and a bait storage tank arranged on the bait storage The lower guide rollers at the bottom of the tank, the rope winding rollers arranged on the deck of the fishing boat and located above the corresponding bait storage tank in one-to-one correspondence, and the second drive motor for driving the rope winding rollers to rotate, the bait is attached to the rope One end of the bait attachment rope is fixed on the rope winding roller on one fishing boat, and the other end of the bait attachment rope is fixed on the rope winding roller on the other fishing boat. A portion of the bait attachment line between the fishing boats hangs in the water.

Description

technical field [0001] The invention relates to a net lifting machine, in particular to a trap type gill net fishing device. Background technique [0002] Current gillnet fishing devices at sea generally include a gillnet and a net lifter, wherein the gillnet is dropped in the sea, and the net lifter is arranged on the deck of a fishing vessel for lifting the net. The gill net lifting machine generally includes a frame arranged on the deck of the fishing ship and close to the side of the ship, a net roller mounted on the frame to rotate, a first drive motor for driving the net roller, and a first drive motor located above the net roller. When the netting machine lifts the net, place the gillnet between the netting roller and the pressing roller, and drive the netting roller to rotate through the first drive motor, so that the gillnet is gradually put away on the ship. The current gillnet fishing method is mainly used for catching migratory fish, mainly relying on artificial...

AI Technical Summary

Problems solved by technology

The current gillnet lifting machine requires the operator to observe the fish catch on the gillnet. When the fish catch on the gillnet is close to the net lifting roller, the operator needs to quickly lift the pressing roller to make the gillnet The fish caught on the net can pass through smoothly, which is not only inconvenient to operate, but also often encounters that the operator does not lift the pinch roller in time, so that the fish caught on the gillnet is stuck between the net lifting roller and the pinch roller, resulting in The problem of fish being crushed
