Investigating the uncertainty of age determinations for Patagonian toothfish (Dissostichus eleginoides) and the implications for stock assessment
Abstract: We revised the method of Candy et al. (2012) to estimate the ageing error matrix (misclassification matrix) to address some issues regarding true ages not being the mode at the extremes of the matrix and a lack of smoothness in the probabilities for ages above 25 years. Positive errors

Report on the CCAMLR marine debris monitoring program
Abstract: Data on beach surveys, debris associated with seabird colonies, marine mammal entanglements and hydrocarbon soilings were received for 2014 from South Africa, the United Kingdom, and Uruguay. Non-fishing items such as plastics, packaging materials and wood remain the most common type of

The demersal fish communities of the shelf and slope of South Georgia and Shag Rocks (CCAMLR Subarea 48.3)
Abstract: Analysis of catch data from a deepwater trawl survey conducted at South Georgia and Shag Rocks in 2003 indicate that depth and region have a marked influence over demersal fish community structure at South Georgia and Shag Rocks. Three distinct, depth stratified fish assemblages were

A perspective on steepness, reference points, and stock assessment
Abstract: We provide a perspective on steepness, reference points for fishery management, and stock assessment. We first review published data and give new results showing that key reference points are fixed when steepness and other life history parameters are fixed in stock assessments using a

Steepness for Antarctic toothfish (Dissostichus mawsoni) based on life history
Abstract: Although steepness is typically considered a convenient re-parametrization of a stock-recruitment relationship, it is deeply rooted in the biology of each species. Furthermore, specifying steepness and other life-history parameters such as natural mortality and growth rates fixes

Maturity stages for skates (Rajiformes)
Abstract: Current CCAMLR maturity stages for skates (Rajiformes) use a three-stage key. As such, important elements of the reproductive cycle may go unrecorded, including females in the process of egg-laying. Additionally, the current description of females at stage 2 (maturing) in the CCAMLR

Revised research plan for the exploratory longline fishery for Dissostichus spp. in Subarea 48.6 in 2014/15
Abstract: Most things related to Dissostichus spp. in the eastern side of Antarctic has not been known well as namely the area is data poor areas. In the Division 58.4.1 there are two stocks; one extends from the SSRU 58.4.1C to the SSRU 58.4.2A, and the other one to the SSRU 58.4.1H. The
