Some aspects of the relation between Antarctic krill abundance and CPUE measures in the Japanese krill fishery. (Component of SC-CAMLR-VI/BG/4)
quality considerations- in particular the increasing tendency to avoid catching "green” krill. These ... factors result in Catch-per-Day and Catch-per-Haul measures being unlikely to index krill abundance ... time data may be needed to assess the density of swarms in a concentration, but may be difficult to ... record in practice, and a number of other factors may complicate any analysis. The possibility of ...

Review of rattail and skate by-catch and analysis of rattail standardised CPUE from the Ross Sea toothfish fishery in Subarea 88.1 from 1997/98 to 2001/02
Abstract: Little is known about the bycatch of skates, rays and macrourids in the target longline ... fishery for toothfish in the Ross Sea. Following concerns about the accuracy of reporting of bycatch ... raised by the 2001 CCAMLR bycatch subgroup, the processes for recording bycatch in this fishery were ... macrourid bycatch in this fishery. The review of data suggest that the toothfish fishery has not yet had a ...
