Seabird research at Cape Shirreff, Livingston Island, Antarctica, 2004/05
Abstract: The eighth complete consecutive season of data collection at Cape Shirreff has enabled us to examine trends in penguin population dynamics, as well as inter-annual variation in penguin diet, and foraging behaviour. The chinstrap breeding population at Cape Shirreff has continued to

Quantifying within- and between-season variability in Adélie penguin fledgling weights: statistical and practical implications for detecting change
Abstract: We develop statistical models of Adélie penguin fledgling weight data collected at Béchervaise Island and use them in a power analysis as a continuation of the CEMP review. The statistical models incorporate both within- and between- season variability of fledgling weights from first

Do Adélie penguin fledgling weights provide an index of prey availability?
Abstract: We examine fledgling weights measured over 11 years at Béchervaise Island in relation to two assumed proxies of prey availability: breeding success and foraging trip duration. Concordance between the two proxies was apparent when considering guard stage foraging trip durations but this

Using carapace measurements to determine the sex of Antarctic krill (Euphausia superba)
Abstract: Krill carapaces measurements have been used to reconstruct krill length frequencies in Antarctic fur seal diet. The discriminant function currently used to determine sex, and the sex-specific allometric equations for calculating total length from carapace length, were derived from South

Modelling growth of Antarctic krill: a new approach to describing the growth trajectory
Abstract: Von Bertalanffy (VB) growth models for Antarctic krill have in the past been calibrated from population-level data consisting of modal lengths obtained from a time sequence of length frequency samples. We develop an alternative approach to predicting the trajectory of length over time

Fishing ground selection in krill fishery: trends in its patterns across years, seasons, and nations
Abstract: Patterns of fishing ground selection were characterized using STATLANT and CCAMLR fine scale data. Among the 15 SSMUs within Areas 48.1, 48.2 and 48.3 including the pelagic SSMUs, only one third of them were identified as the main contributors to the total catch. A shift of operational

CCAMLR observer manual questionnaires: summary results of preliminary analysis during its introductory period
Abstract: Preliminary analysis of data from the questionnaires of krill fishery behavior in CCAMLR observer manual was undertaken. The analysis revealed possible inconsistency in definitions of the event codes among different skippers. Some suggestions were made to improve the quality of

On the use of scientific observers on board krill fishing vessels
Abstract: Wide-scale monitoring of the status of Antarctic krill resources had been previously conducted by the USSR and its results still allow scientist to prepare forecasts of changes in the ecosystem. However, at present such monitoring seems difficult. Taking into account these points,
