Distribution and biological characteristics of two toothfish species of genus Dissostichus (family Nototheniidae) off Bouvet Island
Abstract: In 2010, two toothfish species, Patagonian (D. eliginoides) and Antarctic (D.mawsoni) toothfish, were registered during the fishery on Dissosyichus spp. on the shelf edge and slope of Bouvet Island. Their commercial concentrations were found also on the neighboring underwater plateaus

To the problem of spawning character for certain fish species
Abstract: The present paper presents the brief results of the research in reproductive biology of the Antarctic greinadier M. whitsoni in the Ross Sea. It was stated that the eggs were released by batches. It was supposed that the similar character of spawning might be for some other Antarctic

Connectivity and population structure in Pleuragramma antarcticum
Abstract: We used stable isotope and trace element chemistry from otoliths to test whether silverfish (Pleuragramma antarcticum) are distributed in independent, discrete populations in the Ross Sea, over the West Antarctic Peninsula, and around the South Orkneys; or whether the Southern Ocean

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

Lead-radium dating provides a framework for coordinating age estimation of Patagonian toothfish (Dissostichus eleginoides) between fishing areas
Abstract: Patagonian toothfish (Dissostichus eleginoides) or "Chilean sea bass" support a valuable and controversial fishery, yet their life history is not well understood and longevity estimates range from approximately 20 to more than 50 years. In this study, lead-radium dating

Results from the random stratified trawl surveys to estimate distribution and abundance of Dissostichus eleginoides and Champsocephalus gunnari in the Heard Island region (Division 58.5.2) for 2010 and 2011
Abstract: Random stratified trawl surveys were completed in September 2010 and in March to May 2011 on the RV Southern Champion, adding to the time series of annual surveys in Division 58.5.2 that commenced in 1997. An earlier survey in April 2010 was not completed, but valid hauls from this, as
