1. Revised research plan for toothfish in Divisions 58.4.4a and 58.4.4b by the Shinsei Maru No. 3 in 2010/11

   Abstract:  In order to clarify the stock status and biological characteristics of Dissostichus spp. In Division 58.4.4 a & b, we proposed the research plan for toothfish in the Division by Shinsei Maru No. 3 to be conducted throughout the whole four SSRUs (A-D) in the Division in April-June

2. Analysis of maturity of Antarctic toothfish in the Amundsen Sea

   Abstract:  The results of the comparative histological analysis of the Antarctic toothfish (Dissostichus mawsoni) reproductive system, caught by the longliner in the Amundsen Sea in February 2006 and 2007 are presented. The morphological parameters, indices of gonads, condition by Fulton and

3. Some aspects of the by-catch fish spawning and oogenesis

   Abstract:  On the basis of the biological material collected on some by-catch fishes during Antarctic toothfish fishery from 2002 till 2008 in different areas of the Southern Ocean (Collaboration Sea, D'Urville, Ross and.mundsen Seas) it was established that spawning of C. dewitti and species

5. At-sea distribution and diet of an endangered top predator: links of white-chinned petrels with commercial longline fisheries

   Abstract:  Incidental seabird mortality associated with longline commercial fishing is a worldwide conservation concern. To build conservation strategies it is essential to estimate likelihood of seabird bycatch and amount of overlap between bird’s foraging and commercial fishing areas. We tracked

6. Testing early life connectivity using otolith chemistry and particle-tracking simulations

   Abstract:  We measured the otolith chemistry of adult Scotia Sea icefish (Chaenocephalus aceratus), a species with a long pelagic larval phase, along the Antarctic Circumpolar Current (ACC) and compared the chemistry with simulated particle transport using a circulation model. Material laid down in

7. Latitudinal variation of demersal fish assemblages in the western Ross Sea

   Abstract:  Demersal fishes were sampled using a large fish trawl during two surveys carried out in February and March 2004 and 2008 in the Ross Sea, and around seamounts and islands just to the north at 66°S. The distribution and abundance of 65 species collected in these surveys were examined to

8. Distribution, abundance and acoustic properties of Antarctic silverfish (Pleuragramma antarcticum) in the Ross Sea

   Abstract:  Antarctic silverfish (Pleuragramma antarcticum) is a key link between plankton and the community of top predators in the shelf waters of the Ross Sea. In spite of their abundance and important role in Antarctic food chains, very little is known of many ecological and biological aspects

9. The Patagonian toothfish: biology, ecology and fishery

   Abstract:  Patagonian toothfish (Dissostichus eleginoides) is a large notothenioid fish that supports valuable fisheries throughout the Southern Ocean. D. eleginoides are found on the southern shelves and slopes of South America and around the sub-Antarctic islands of the Southern Ocean. Patagonian

10. Estimating the impact of depredation by killer whales and sperm whales on longline fishing for toothfish (Dissostichus eleginoides) around South Georgia

    Abstract:  Observer data collected on longliners between 2003 and 2009 were analysed to look at the levels of depredation caused by killer whales (Orcinus orca) and sperm whales (Physeter macrocephalus) around South Georgia. Since 2003, cetaceans have been observed on 22% of 14 300 observed lines,
