By-catch of fishes caught by the fishery vessel Niitaka Maru in the South Georgia area (August to September 2004)
Abstract: Scientific observations on fishes incidentally caught during commercial krill fisheries by F/V Niitaka Maru (5306t) were made from August 6 to September 9, 2004 to the north of South Georgia Island. Among 100 net hauls quantitatively examined, a total of 12 species belonging to 6

Detection of systematic change in Adélie penguin foraging trip duration: consequences of high inter-annual variability and usefulness of ice cover as a covariate
Abstract: Power analyses were carried out using a 12 year data set from the Béchervaise Island Adélie penguin colony with the aim of determining minimum sample sizes required to detect systematic temporal change in CEMP Parameter A5 (penguin foraging trip duration). Two different types of

Estimating the abundance of pack-ice seals off east Antarctica
Abstract: A survey was undertaken to provide estimates of the abundance of crabeater, Ross and leopard seal populations in 1,500,000 km2 of pack-ice off east Antarctica between longitudes 60-150oE. Sighting surveys were undertaken along almost 10,000 km of survey transect from an icebreaker and

A quantified Bayesian maximum entropy estimate of Antarctic krill abundance across the Scotia Sea and in small-scale management units from the 2000 CCAMLR survey
Abstract: We present the results of an alternative method of estimating krill abundance, and producing maps of krill distribution, from the data collected during the 2000 CCAMLR survey of the Scotia Sea. Using a probabilistic Bayesian Maximum Entropy (MaxEnt) technique, density values for the

Approaches to monitoring and assessing the abundance of rattails (Macrourus spp.) and skates in the Ross Sea
Abstract: This report presents results from a desktop study to consider approaches to monitoring and assessing rattails and skates, which are major bycatch species in the exploratory fishery for toothfish in the Ross Sea. We review standardised CPUE analysis, quantitative research longline surveys

Towards a validation of ageing in mackerel icefish (Champsocephalus gunnari) – can we estimate age more accurately?
Abstract: Age estimates of mackerel icefish from different laboratories obtained during a CCAMLR ototlith exchange programme in the late 1980’s revealed considerable differences between readers when fish older than 3 or 4 years were aged. These differences could not be reconciled at the end of the
