1. Linking fish and shags population trends

   Abstract:  This document analyses and relates long term information on population trends of inshore demersal fish and Antarctic shags of the South Shetland Islands. The analysis is complemented with comparable information on diet, foraging patterns and breeding output of shags from the Danco Coast,

2. A updated population status model for the Patagonian toothfish, Dissostichus eleginoides, at Kerguelen Islands (Division 58.5.1) using CASAL

   Abstract:  A stock assessment of the Patagonian toothfish (Dissostichus eleginoides) at Kerguelen Islands (CCAMLR Division 58.5.1) was undertaken using the modelling software CASAL, based on different statistical and biological datasets: abundance estimation from the POKER 1 (2006) and 2 (2010)

3. The composition, abundance and reproductive characteristics of the demersal fish fauna in the Elephant Island–South Shetland Islands region and at the tip of the Antarctic Peninsula (CCAMLR Subarea 48.1) in March–early April 2012

   Abstract:  A bottom trawl survey for demersal finfish was undertaken by Germany aboard R/V ‘ Polarstern ’ around Elephant Island, the South Shetland Islands and at the tip of the Antarctic Peninsula from 17 March to 5 April 2012. In this paper we provide information on species composition, biomass,

4. Dissostichus mawsoni distribution and biology

   Abstract:  The present work includes results of seven-year own author’s research and presents generalised knowledge about distribution and biology of the antarctic toothfish in different sectors of the Antarctica. Author(s):  A.F. Petrov (Russia) Title:  Dissostichus mawsoni distribution and

5. Does large-scale ocean circulation structure life history connectivity in Antarctic toothfish (Dissostichus mawsoni)?

   Abstract:  A multi-disciplinary approach incorporating otolith chemistry, age data and numerical Lagrangian particle simulations indicated a single, self-recruiting population of Antarctic toothfish (Dissostichus mawsoni) in the Southeast Pacific Basin (SPB) and Ross Sea, with a life history

6. Trophic interactions and population trends of killer whales (Orcinus orca) in the southern Ross Sea

   Abstract:  Foraging events and related trends in numbers of Type-B and-C killer whales (Orcinus orca) are reported for the vicinity of Ross Island, Ross Sea, Antarctica, between 2002 and 2010. Updating an earlier report, the frequency of sightings and the number of individuals per sighting of Ross

7. Decadal trends in abundance, size and condition of Antarctic toothfish in McMurdo Sound, Antarctica, 1972–2011

   Abstract:  We report the analyses of a dataset spanning 39 years of near-annual fishing for Dissostichus mawsoni in McMurdo Sound, Antarctica, 1972–2011. Data on total length, condition and catch per unit effort (CPUE) were derived from the > 5500 fish caught, the large majority of which were

9. Influence of the quality and quantity of data from a multi-year tagging program on bias and precision of biomass estimates from an integrated stock assessment – update

   Abstract:  By way of simulation, this study investigated how the bias and precision of biomass estimates from an integrated tag-based assessment are influenced by various aspects of a multi-year tagging program, in particular the effects of the size (tag size-overlap) and numbers of tagged fish,

10. Has Notothenia rossii around Elephant Island and the lower South Shetland Islands (Subarea 48.1) recovered from exploitation some 30 years ago?

    Abstract:  The marbled notothenia (Notothenia rossii) was the first species targeted by commercial fishing in the Southern Ocean. The species has been heavily fished around South Georgia and Iles Kerguelen in the first half of the 1970’s and at Elephant Island in 1979/80. The closure of the fishery
