SHIPEND HOPPERTYPE KRILLWATER SEPARATING AND CONVEYING DEVICE FOR ANTARCTIC KRILL TECHNICAL FIELD

[01] The present invention relates to a shipend hopper type krillwater separating and conveying device for Antarctic krill, and Ibelongs to the technical field. of fishery machinery. BACKGROUND ART

[02] All fishery activities in Antarctic waters are strictly' managed. by Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). CCAMLR implements partitioned quota fishing management for Antarctic krill fishery, and krill fishing is in an international competition situation, that is, the total amount of fishing is certain, the greater the fishing capacity, the greater the competitive advantage of fishing ships. In recent years, there are mainly krill ships from Norway, South Korea, China, Ukraine, Chile and other countries engaged in Antarctic krill fishery. At present, Norway has three continuouspumping professional krill fishing and processing ships, China has one selfdeveloped continuouspumping professional fishing and processing ship, and the rest are traditional stern ramp trawlers. The annual output of continuouspumping krill ship accounts for more than half of the total krill output. The fishery developed countries represented. by Norway have turned Antarctic krill fishery into a new marine biological industry supported. by efficient fishing technology, driven by high valueadded products, integrating fishing and shipborne processing, showing a new form with high technical threshold, long industrial chain and greatly improved economic benefits step by step, and fully demonstrating' the great productivity of innovative technologies.
