Update on the analysis of fish by-catch in the krill fishery using data from the CCAMLR Scheme of Scientific Observation
Abstract: Data on fish bycatch in the krill fishery has been collected as part of the CCAMLR SISO from a total of 9303 hauls collected on 60 cruise involving 18 different vessels over the period 2010-2014. This paper examines the frequency of occurrence, proportion by mass and length-frequency

Congruent, decreasing trends of Gentoo Penguins and Crozet Shags at sub-Antarctic Marion Island suggest food limitation through common environmental forcing
Abstract: Numbers of Gentoo Penguins Pygoscelis papua and Crozet Shags Phalacrocorax [atriceps] melanogenis breeding annually at Marion Island, one of South Africa’s Prince Edward Islands in the south-west Indian Ocean, were strongly correlated over 19 split-years from 1994/95–2012/13. Both

A preliminary CASAL population assessment of Patagonian toothfish in CCAMLR Subarea 48.4 based on data for the 2009–2014 fishing seasons
Abstract: This paper describes a preliminary CASAL based assessment of Patagonian toothfish (D. eleginoides) in Subarea 48.4. The assessment data are updated with the observations for the 2013/14 season and sensitivity analyses conducted using the maturity ogive from the area 48.3 and revised

Bycatch of skates (Rajiformes) and grenadiers (Macrouridae) in longline fisheries in Subarea 48.3
Abstract: This paper investigates factors affecting the bycatch of skates (Rajiformes) and grenadiers (Macrouridae) taken by the longline fishery in statistical subarea 48.3. Bycatch was greater for vessels using autoline system than for those using the “Spanish” system, due to differences in

A Petersen tag-recapture preliminary population assessment of Antarctic toothfish in CCAMLR Subarea 48.4 based on data for the 2009–2014 fishing seasons
Abstract: The stock of Antarctic toothfish (D. mawsoni) in CCAMLR subarea 48.4 was estimated from tagging returns to be 1,027 tonnes during the 2013/14 season. In previous years the harvest rate used for Patagonian toothfish (D. eleginoides) in Subarea 48.3 (γ = 0.038) has been used as a

Updated and revised stock assessments of Patagonian toothfish (Dissostichus eleginoides) in the vicinity of Kerguelen Islands (Division 58.5.1) and Crozet Islands (Subarea 58.6)
Abstract: An updated and revised assessment of the Patagonian toothfish (Dissostichus eleginoides) stocks in Kerguelen and Crozet areas is presented. This study is based on a CASAL (C++ Algorithmic Stock Assessment Laboratory) model. Different statistical and biological datasets are used: catches,

Quantifying the impacts of ice on demersal longlining; a case study in CCAMLR Subarea 88.1
Abstract: The effect of sea ice is acknowledged as a major influence on fishing operations in high latitudes but not widely understood in detail other than by fishers and specialists in Antarctic fisheries research and management. Using the toothfish fishery in CCAMLR Subarea 88.1 as a case study
