1. Species profile of mackerel icefish (Champsocephalus gunnari)

   Abstract:  Mackerel icefish (Champsocephalus gunnari) has been exploited since the early 1970’s and became the target species of fisheries in many parts of the low-Antarctic from 1975 to 1990. Exploitation has been limited to South Georgia and Heard and McDonald Islands since the second half of the

2. Autoliners and seabird by-catch: do line setters increase the sink rate of integrated weight longlines?

   Abstract:  Line setters are used with integrated weight (50 g/m lead core, IW) by some autoline vessels in the Kerguelen and Crozet Islands Patagonian toothfish fisheries to deter seabirds, ostensibly by expediting gear sink rates. A trial was conducted in the Ross Sea in 2007 to determine the

3. A new fishing gear in the Chilean Patagonian toothfish fishery to minimise interactions with toothed whales with associated benefits to seabird conservation

   Abstract:  We describe a new fishing technique, called the Chilean system, adapted from an artisan fishery for Patagonian Toothfish. The artisan system was modified to include a net sleeve that is placed on secondary vertical lines, which has practically eliminated depredation by killer whales and

4. Line weights of constant mass (and sink rates) for Spanish-rig Patagonian toothfish longline vessels

   Abstract:  CCAMLR Conservation Measure 25-02 requires Spanish system longline vessels attach 8.5 kg weights at 40 m intervals on longlines to minimise interactions with seabirds. The weights are collections of rocks enclosed in netting bags. The netting bags abrade on the seabed, rocks are lost and

5. Biomass abundance and distribution of fish in the Kerguelen Islands’ zone (Division 58.5.1)

   Abstract:  A fish biomass survey cruise, named POKER 2006, was conducted during spring 2006/07 (September-October 2006) off the Kerguelen Islands (division 58-5-1), the northern part of the Kerguelen Plateau. The sweep-area method was used in the range 100 and 1000 m with random stratified stations

6. 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

7. 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

8. 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

9. 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

10. 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
