Description

Fishing system and fishing boat

Technical Field

The invention relates to the technical field of fishing, in particular to a fishing system and a fishing boat.

Background

Currently, more and more countries are concerned about krill fishing, wherein fishing ships are available in norway, russia, korea, japan and china for krill fishing in the antarctic region. The existing krill catching mode adopts a traditional trawl method for trawl catching in a middle layer of a large trawl boat, when the trawl is fished in the catching operation, a net tool is hauled to a deck by a net rolling machine through a tail slide way at the tail of the trawl boat, a net bag is hoisted by a mast hoisting hook, and the krill is directly poured into a buffer cabin of a lower deck through an opening of the buffer cabin on the deck. The krill live in seawater at 0 to-1 ℃, once the water is fished, the special protease positioned on the head and chest changes due to the temperature rise to cause autolysis, once the water is not treated for more than 2 hours, the shrimp shell is blurred, the shrimp tail bends, the body of the untreated krill turns grey or black after the water is treated for more than 4 hours, and yellow green liquid flows out.

By adopting the fishing method, the net falling, the trawl and the net lifting are repeated, the effective trawl fishing time is not large, the krill is accumulated in the sac net and is easy to extrude and damage after the underwater trawl is too long, and meanwhile, the krill can generate a large damage rate in the extrusion process when being dragged to the deck, so that the quality of the krill is seriously influenced. The traditional trawl fishing is not only low in efficiency, but also high in krill breakage rate, so that the traditional trawl fishing mode is not suitable for krill fishing operation.
