Catch Pattern for Antarctic krill ( Euphausia superba ) of Different Commercial Trawls in Similar Times and Overlapping Fishing Grounds
Antarctic krill ( Euphausia superba ) is harvested using different design midwater trawls. Knowing the selective properties between trawls is crucial information for the management of the krill resources. This study compared the catch patterns between different commercial krill trawls at similar tim...
