The Ross Sea toothfish fishery: proposal for conditional transition of classification from exploratory to established
Abstract: The Ross Sea toothfish fishery in Subarea 88.1 and 88.2A&B has been classified by CCAMLR as an exploratory fishery since 1998. The current classification of this fishery as ‘exploratory’ has led to the widespread misconception that little information is available for this stock, and

Proposal to trial daylight setting on longliners fishing for Dissostichus eleginoides for a 10 day period during the middle of winter during the fishing season in Subarea 48.3
Abstract: Daylight setting is allowed in Subarea 48.4 and stringent mitigation measures have meant to date no bird mortalities have been recorded. Due to frequent storms vessels have been requesting the option to be able to set during daylight in Subarea 48.3 for safety reasons. Recurrent

Recommendation for an explicit limit reference point for the mackerel icefish (Champsocephalus gunnari) fishery in CCAMLR Statistical Division 58.5.2
Abstract: Large fluctuations in abundance are a persistent feature of the populations of mackerel icefish (Champsocephalus gunnari) in the waters adjacent to Heard Island and the McDonald Islands in CCAMLR Statistical Division 58.5.2. The current decision rules for setting catch limits for icefish

Estimation of catch rate and mean weight in the exploratory Dissostichus fisheries across Divisions 58.4.1 and 58.4.2 using generalised additive models
Abstract: The exploratory longline fisheries in Divisions 58.4.1 and 58.4.2 (primarily targeting D. mawsoni) have been operating since 2003. Formal stock assessments have yet to be developed for these fisheries. Analyses of C2 catch rate and mean weight data from 2484 longline hauls conducted

Finfish by-catch in the krill fishery for the 2010 and 2011 seasons
Abstract: The fish sampling protocol (K12 form) was developed to ensure that small/larval fish, that may go undetected in larger samples, are recorded using a sorting method with a standard sub-sampling approach that allows the user to re-sort smaller samples and maximises potential to detect by

Revised proposal for a CCAMLR sponsored research survey to monitor abundance of pre-recruit Antarctic toothfish in the southern Ross Sea
Abstract: At its 2010 meeting, the Scientific Committee agreed that a time series of recruitments from a well- designed survey in the Ross Sea could be a useful input into the stock assessment model and requested members develop a pre-recruit survey design. A preliminary proposal for a pre-recruit

Development of a generic operating model framework for data collection, assessment method and management strategy evaluations
Abstract: A generic spatially-explicit age-structured model framework is in development that will enable to evaluate data collection protocols, assessment methods and management strategies. The model framework is programmed in R to promote transparency and interactions between researchers. It is

Estimates of the tag loss rates for single and double tagged toothfish (Dissostichus mawsoni) fishery in the Ross Sea
Abstract: The rate at which tags are lost from tagged toothfish is an important parameter in modelling of the Antarctic toothfish (Dissostichus mawsoni) populations in Subarea 88.1 and 88.2. The toothfish stocks in these areas have been assessed using data from tag-release and recapture

Report on the results of exploratory research fishing for crabs in Subarea 48.2 on board FV Tamango in the 2009/10 season
Abstract: Exploratory research voyage of F/V 'TAMANGO' proceeded from March, 23 to May, 8, 2010. Three areas were explored during the voyage: Patagonian shelf (Statistic Subarea 41.3.1), South Orkney Islands shelf (CCAMLR Subarea 48.2) and the North Scotia Ridge. Exploratory pot-line
