WG-FSA-01/16 More Info	Length-at-age juvenile Patagonian toothfish Dissostichus eleginoides J. Ashford (USA), I. Everson (UK), C. Jones and S. Bobko (USA) Abstract: The fishery for Patagonian toothfish is one of the most valuable in the CCAMLR Area. Age based models are used to assess the status of the stocks of this species. Although age can be estimated using otoliths it has proven difficult for these to be validated. During a recent trawl survey the length density of juvenile toothfish in the catches had a clearly defined polymodal distribution. The Read More Submitted By: Admin Admin (CCAMLR Secretariat) Request Meeting Document
WG-FSA-01/17 More Info	Problems in estimating population length at age from commercial catches, the Patagonian toothfish as an example I. Everson (United Kingdom) Abstract: Age based fishery population models require information on size at age of the fished population and the commercial catch. Age-length keys can be produced by standardised random sampling of the commercial catches. This information does not necessarily reflect the size at age of the fished population and may be seriously biased. Through the use of a model, and using the Patagonian toothfish as Read More Submitted By: Admin Admin (CCAMLR Secretariat) Request Meeting Document
WG-FSA-01/18 More Info	Modelling the impact of fishery by-catches on albatross populations G. Tuck, T. Polacheck (Australia), J.P. Croxall (UK) and H. Weimerskirch (France) Abstract: 1. Several albatross species, including the wandering albatross Diomedea exulans , have shown marked declines in abundance throughout their range. These seabirds are frequently taken as by-catch in longline fisheries and this mortality has been implicated in the population declines. 2. We developed a deterministic, density-dependent, age-structured model for assessing the effects of Read More Submitted By: Admin Admin (CCAMLR Secretariat) Request Meeting Document
WG-FSA-01/19 More Info	Global relationships amongst black-browed albatrosses: analysis of population structure using mtDNA and microsatellites T.M. Burg and J.P. Croxall (United Kingdom) Abstract: The population structure of black-browed (Thalassarche melanophris and T. impavida) and grey-headed (T. chrysostoma) albatrosses was examined using both mitochondrial DNA (mtDNA) and microsatellite analyses. mtDNA sequences from 73 black-browed and 50 grey-headed albatrosses were obtained from five island groups in the Southern Ocean.

Berezhinskiy (Russia) Abstract: Two sequential groundfish surveys in January-February 2000 revealed very different distribution of Raja georgiana, rather abundant species on the South Georgia shelf. The adult rays longer 206 mm were not caught during the second survey, the first one did not reveal such anomaly. The reasons which may caused such an absence are discussed.

WG-FSA-01/39 More Info	Otolith and body size relationships in the bigeye grenadier (Macrourus holotrachys) in CCAMLR Subarea 48.3 S. Morley and M. Belchier (United Kingdom) Abstract: A large sample of otoliths from Bigeye Grenadier (Macrouros holotrachys) caught as bycatch in the Toothfish (Dissostichus eleginoides) fishery in subarea 48.3 were measured and weighed and their usefulness as predictors of fish size was determined. Otolith mass provides a good measure of fish length whereas otolith length and width measurements provide less accurate estimates of fish length.

WG-FSA-01/54 More Info	A first attempt at an assessment of the Patagonian toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands EEZ A. Brandão, B.P. Watkins, D.S. Butterworth and D.G.M. Miller (South Africa) Abstract: The history of the fishery for Patagonian toothfish in the Prince Edward Islands EEZ is reviewed briefly. It is characterised by very large illegal catches and a sharply declining longline CPUE trend. Application of a simple age-structured production model provides robust indication that the spawning biomass has been depleted to at most a few percent only of its pre-exploitation level.
