    Abstract

    The characteristics of Japanese krill fishery were reviewed in several examples based on the information recorded on log book. While searching behaviour seems to be the basis of this fishery, CPUE in terms of catch per minute of towing was thought to be an useful index of patch density and possibly of local abundance.
