Preliminary assessment of Subarea 48.3 mackerel icefish, Champsocephalus gunnari, based on the January 2013 survey
Abstract: A bootstrap procedure was applied to estimate the demersal biomass of mackerel icefish (Champsocephalus gunnari) in CCAMLR subarea 48.3 using data from the UK trawl survey conducted in January 2013. The CCAMLR harvest control rule was then applied to determine catch limits for the 2013

An overview of the elasmobranch fish of the Southern Ocean
Abstract: This review summarises current knowledge of the elasmobranch fish occurring in the Antarctic and sub-Antarctic waters of the CCAMLR area. About 14–15 species of elasmobranch have been recorded, with skates (Rajiformes) the most speciose order. Two genera of skates are known (Amblyraja

A brief characterisation of Patagonian toothfish tag survival and tag detection in CCAMLR Statistical Area 48.3
Abstract: Mark-recapture data is a central element in the assessment of population size and growth and the stock assessment for Patagonian Toothfish (Dissostichus eleginoides) in CCAMLR subarea 48.3 relies on accurate tagging samples for its assessment. The bias in tagging survival and tag

Preliminary assessment of Patagonian toothfish in Subarea 48.3
Abstract: A preliminary assessment of toothfish (Dissostichus eleginoides.) in Subarea 48.3 is presented. The assessment results from this year’s analyses are very similar to those of 2011. SSB in the terminal assessment year continues to be estimated at around 54% of virgin biomass, consistent

Preliminary assessment of Patagonian toothfish in Subarea 48.4
Abstract: To date, the stocks of toothfish in Subarea 48.4 have been divided, for assessment purposes, into northern and southern components. The northern component is assessed as a single species of D. eleginoides whilst the southern component is assessed as a combination of D.eleginoides and D.

Review of the efficacy of the early season extension in the Patagonian toothfish fishery in Subarea 48.3 and proposal for further season extension
Abstract: In 2009 CCAMLR agreed to incrementally and conditionally bring forward the start date of the Patagonian toothfish fishery in sub-Area 48.3. This allowed vessels that had been 100% compliant with CM 25-01 in the previous season to start 5-days early in 2010 (April 26th) and a further 5

An overview of tagging skates (Rajiformes) and CCAMLR skate tagging data
Abstract: Tagging studies of skates and rays worldwide provide valuable information to help better understand a wide range of metrics including movements and migrations, stock units, growth rates, longevity, discard survival and abundance. Most Antarctic skate species are little known and, coupled

Revised research plan for the 2013/14 exploratory longline fishery of Dissostichus spp. in Subarea 48.6
Abstract: Catch and effort data recorded by all vessels were analyzed using the latest CCAMLR C2 and observer data. The stock size estimates for research blocks were revised following advice in the last WG-SAM meeting. We tentatively recalculated a sample size of Dissostichus spp in each block in

The relative by-catches of taxa associated with vulnerable marine ecosystems by autolines and Spanish longlines
Abstract: We reanalyzed data collected by the longline fishery in Subarea 88.1 to compare the bycatches of VME taxa made by vessels using Autolines and Spanish longlines. The fractions of sets with positive bycatch, as well as the weights of bycatch when bycatches were observed, were higher for
