5. A review of rattail (Macrourus spp.) and skate by-catch and analysis of standardised CPUE, for the exploratory fishery in the Ross Sea (CCAMLR Subareas 88.1 and 88.2) from 1997/98 to 2004/05

   Abstract:  A standardised CPUE analysis was used to determine factors affecting bycatch rates of ... were vessel, area, and depth. Catch rates of rattails were highest along the shelf edge (SSRUs 88.1E ... , 88.1I, 88.1K and 88.2E) in depths from 600 to 1000 m, and there was an order of magnitude difference in ... rattail catch rates between different vessels. Examination of vessel characteristics showed that catch ...
