Description

Multi-net bag type antarctic krill continuous pump suction fishing

Technical Field

The invention belongs to the technical field of fishery, and particularly relates to multi-net bag type continuous pumping fishing of antarctic krill.

Background

Antarctic krill (academic name: eucheuma superba) is a krill that lives in Antarctic waters of the Nanicyan, and has shrimp length of 45-60 mm, the maximum of 90 mm. The antarctic krill giardia paste contains a large amount of chitin, and a certain amount of astaxanthin, krill oil and other substances in the body, and has the characteristics of high protein and low fat. Because the antarctic krill has abundant nutritive value, the demand of each country for the antarctic krill is increasing year by year.

The antarctic krill is usually caught by trawl catching method, which is one of the main operation modes in the marine catching industry. The trawl operation catches the object extremely greatly, can carry on the operation in the large scale, produce and initiatively nimble, catch high efficiency, hold the very important position in fishery production. However, under the condition of a large amount of fishing operation, aquatic organisms except the target capture object are easy to carry and capture, the living capacity of the organisms is poor, the organisms are easy to die after being fished ashore, the organisms are extremely easy to die, the irreversible damage to the ecological system of the ocean is caused, the capacity of the trawl is limited, other organisms can reduce the acquisition amount of the target capture object, and the trawl is easy to explode, so that economic loss is caused.

European patent publication No. EP1465803B1 discloses a trawl boat for use with a trawl net for capturing marine biological resources, the invention comprising a trawl net having a trawl bag at the end, a rope connected to the boat and the trawl net and a trawl reel for towing the trawl net, the boat having a lock chamber with a main portion located below the water line of the boat for holding captured matter, the lock chamber having a trunk passageway upwardly. The device realizes that the captured objects are brought to the ship of the trawl ship in a mild way through the arrangement mode of the lock chambers and the trunk channel relative to the trawl, avoids the crushing of the dead fishes and shrimps, and reduces the economic loss. The invention has the following defects in the technical scheme: after the trawl collects fish and shrimp, the seabird circling in the air is easy to attract and stay on the trawl to gnaw the fish in the trawl, so that economic loss is caused, and the seabird instrument is easy to pull to drag to cause death, so that the ecological environment is damaged; when the shrimp is caught, the trawl meshes are too large, and the shrimp and shellfish are easily washed out of the meshes by the moving water flow, so that the resource loss is caused.
