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

CEMP Indices: 2015 update on data submissions and analyses
Abstract: The CCAMLR Ecosystem Monitoring Program (CEMP) was established to detect changes in krill-based ecosystems to provide a basis for regulating harvesting of Antarctic living marine resources in accordance with the ‘ecosystem approach’. In 2015 data has been submitted by 9 Members for 15

A biomass estimate of Antarctic krill (Euphausia superba) at the Balleny Islands
Abstract: The biomass of Antarctic krill (Euphausia superba) at the Balleny Islands, Antarctica (67° S 163° E) was estimated from an acoustic transect survey carried out in February 2015. Acoustic data processing followed the recommendations of CCAMLR SG-ASAM. Two parameterisations of the krill

A candidate process for managing the krill fishery at a local scale for krill predators, particularly in the early phases of the development of the krill fishery
Abstract: In this paper, we develop a candidate management system for the krill fishery suitable for achieving objectives for krill and its predators in local areas. We also indicate how this management system can be made operational in the early phases of a fishery in a local area, which can then

Estimating future krill catches that meet the CCAMLR and alternative decision rules for FAO Subarea 48.1 using an integrated assessment model
Abstract: An integrated assessment model for Antarctic krill in FAO Subarea 48.1 that incorporates catch and length-composition data from the krill fishery with biomass indices and length-compositions from research surveys has been developed. The model uses statistical fits to these data to
