  1. A conceptual model of Japanese krill fishery

    Abstract:  The behaviour patterns of Japanese krill fishery vessels in Area 48 were analysed using ... , krill density, krill, size, ice condition, transshipment, and salp-by catch accounted for 95.6% of the ... changes. Although low krill density was the primary reason for changing fishing grounds, other seasonal ... succession of the Japanese krill fishing operation revealed that they tend to utilize fishing grounds close ...
