Species profile for Antarctic toothfish (Dissostichus mawsoni)
Abstract: A toothfish species profile, covering aspects of the biology, fisheries and stock assessment of both toothfish species was completed by Everson (2002). Aspects of the biology of D. mawsoni were summarised by Hanchet et al. (2003), whilst more recent research has been reported in

Stomach contents of sub-adult Antarctic toothfish (Dissostichus mawsoni) from the western Ross Sea, Antarctica
Abstract: The stomach contents of 190 sub-adult (51-100 cm TL) Antarctic toothfish (Dissostichus mawsoni) captured by bottom longline in the western Ross Sea were analysed. Fish were sampled during the 2005 fishing (Dec 2004 to Jun 2005) season and caught in 398-1678 m depths. Sub-adult D. mawsoni

Some thoughts on the CCAMLR risk assessment for seabird–fishery interactions
Abstract: The CCAMLR system for assessing risk of fisheries mortalities to seabirds has been applied for 10 years and helps to define mitigation and monitoring requirements for fisheries within the waters of the CCAMLR convention area. Annual review of the information by used CCAMLR Working Group

Estimating fishing gear selectivity for trawlers using length-frequency data from concurrent commercial trawl and longline fishing for Patagonian toothfish in Division 58.5.2 and the ratio of their hazard functions
Abstract: The upper-arm of the length-dependent fishing selectivity function for trawlers fishing for Patagonian toothfish around Heard Island (Division 58.5.2) was modelled as the exponential of a quadratic function in length. This function was calibrated using random length frequency (LF) data

Assessment of toothfish in Subarea 48.3, 2006
Abstract: 1. As requested by SAM-2006, we provide a reference assessment for toothfish in Subarea 48.3. We provide sensitivity runs that include revised maturity and catch weighted proportion at length data. We additionally provide a sensitivity run which examines uncertainty in IUU catches from

Estimates of natural and fishing mortality from toothfish mark–recapture and catch-at-age data at South Georgia
Abstract: This paper presents new results and estimation bias analyses for a Bayesian mark-recapture model, applied to the South Georgia toothfish tagging data. The updated model incorporates the data from all the analysed cohorts in the estimation routine, and we examine the potential estimation

A proposal methodology to assess the Patagonian toothfish stock abundance at CCAMLR Subarea 48.3 using ASPM
Abstract: The ASPM is an integrated modeling technique used in stock assessment of different D. eleginoides fisheries (Prince Edward Islands and Patagonian Shelf) and allows fitting to many different information sources, such as catch and age and size data from fishing fleet, surveys and others

Comparison of census methods for black-browed albatrosses breeding at the Ildefonso Archipelago, Chile
Abstract: Although a breeding population of black-browed albatrosses has been known to exist at the Ildefonso Archipelago, Chile, for > 90 years the population has never been censused using scientifically defendable methods. To estimate population size, and examine the accuracy and practicality
