1. Proposal to extend the fishing season for longline fishing in CCAMLR Statistical Division 58.5.2

   Abstract:  This paper summarises the historic effort and seabird bycatch mitigation measures that have applied to the Patagonian toothfish longline fishery in CCAMLR statistical division 58.5.2. It suggests that there is now sufficient experience to show that fishing under the current season timing

2. Effect of two natural repellents on the depredation of mackerel baits by white-chinned petrels (Procellaria aequinoctialis)

   Abstract:  Longline fisheries worldwide have interactions that can be harmful or fatal to seabirds. We report preliminary testing of potential seabird deterrents in longline fisheries around the sub-Antarctic Kerguelen Islands. We compared White-chinned Petrel (Procellaria aequinoctialis) responses

3. Experience with seabird by-catch limits in a trial of longline fishing in the Macquarie Island toothfish fishery

   Abstract:  The Australian Fisheries Management Authority (AFMA) recently granted a permit for a trial of longline fishing in the Macquarie Island toothfish (Dissostichus spp.) fishery, which lies just outside the CCAMLR Area. Several threatened seabird species, including albatrosses and petrels

4. Educational poster on hook ingestion

   Abstract:  Since the 2001/2002 season CCAMLR has recognised the importance of the high level of hooks discarded in fish heads which ingestion by seabirds, especially wandering albatrosses which are large enough to swallow fish heads whole (SC-CAMLRR-XXI/BG/7). For example, in 2001/02 the scientific

5. Biology and distribution of South Georgia icefish (Pseudochaenichthys georgianus) around South Georgia and Shag Rocks

   Abstract:  Pseudochaenichthys georgianus is a member of the unique Channichthyidae family, which lack haemoglobin. The distribution, length-frequency and summer diet are described from 14 bottom trawl surveys undertaken in the austral summers between 1986 and 2006. P. georgianus (50-590 mm Total

6. Composition and standing stock estimates of finfish from the Polarstern bottom trawl survey around Elephant Island and the South Shetland Islands (Subarea 48.1, 19 December 2006 to 3 January 2007)

   Abstract:  Germany conducted a bottom trawl survey aboard R/V ‘Polarstern’ around Elephant Island and the South Shetland Islands from 19 December 2006 to 3 January 2007. Information on species composition, biomass, and size composition of the abundant fish species was provided. Estimates of total

7. Interaction of sperm whales with bottom longline and the Mammal and Bird Excluding Device (MBED) operation in the Patagonian toothfish (Dissostichus eleginoides) fishery in the southwestern Atlantic

   Abstract:  This paper describes the interaction between sperm whales (Physeter macrocephalus) and the toothfish fishery (Dissostichus eleginoides) carried out by longline fishing vessels operating in two different fishing zones at 40º and 50º latitudes in the Southwestern Atlantic from March to May

8. Mercury concentrations of five species of Antarctic fish collected from CCAMLR Subareas 88.1 and 88.2

   Abstract:  The mean mercury level for the D. eleginoides 1998 sample was 0.43 mg/kg-1, which is slightly lower than the permissible level of 0.5 mg/kg-1 set by the New Zealand Food Safety Authority (NZFSA). In contrast, mean levels of mercury for D. mawsoni were 0.10 mg/kg-1 in the 1998 samples and

9. Biological parameters for icefish (Chionobathyscus dewitti) in the Ross Sea, Antarctica

   Abstract:  Icefish (Channichthyidae) specimens were randomly collected by observers during the 2005–06 fishing season. These observers were placed aboard three longline vessels targeting Antarctic toothfish in the Ross Sea (Areas 88.1 and 88.2). Biological data from 303 returned specimens was

10. Identification and speciation of Antarctic skates

    Abstract:  Two regions of mitochondrial (mt) DNA: cytochrome b and cytochrome c oxidase subunit 1(COI) were sequenced in 9 species of Bathyraja skates from the Southern Oceans and New Zealand. Based on significant sequence divergence, the species that has been referred to as Bathyraja eatonii from
