Fishing principle of squid ship

Squid boat, is to use the phototaxis of squid, put the hook with plastic luminous body into the sea, and the squid can't get rid of the hook. On the high seas, the water layer is very deep, and the ordinary sea anchor of the general fishing boat can't reach the seabed. It is difficult to catch squid in the deep sea by using lights instead of bait.

It is a revolution from purse seine fishing to light trapping, but this technology has been perfected and applied to squid fishing, and the parachute anchor is combined to stabilize the ship to achieve the fishing purpose. Light source is an important part of light-induced squid fishing.

Effective and reasonable use of lighting can not only save energy, but also attract more squid, thus improving the catch rate and catch. It involves many research contents, such as ship type, layout, accessories and the best light intensity of different ship types.
