Considerations about managing the krill fishery at small spatial and temporal scales
managing the krill fishery at small temporal and spatial scales. We highlight that the devil is in the ... coastal areas. Closed coastal areas potentially protect near-shore krill-dependent predators from the ... closed coastal buffers will alter the potential levels of catch displacement, and therefore highlights ... the need for coupled research to ensure fishery displacement does not become too concentrated in other ...

Extinction risk of Antarctic and sub-Antarctic colonies of Pygoscelid penguins under climate change context
Abstract: Several studies have emphasized the variable abundance of Pygoscelid penguins from ... different colonies around Antarctica. In this study, the extinction risk of Adélie, Chinstrap and Gentoo ... penguins was evaluated in order to identify the most endangered colonies under present-day and future ... environmental scenarios. The extinction risk was estimated for twelve colonies from environmentally contrasting ...

Krill (Euphausia superba) distribution contracts southward during rapid regional warming
Abstract: High-latitude ecosystems are among the fastest warming on the planet. Polar species may ... that, within their main population centre in the southwest Atlantic sector, the distribution of ... Euphausia superba (hereafter, ‘krill’) has contracted southward over the past 90 years. Near their northern ... limit, numerical densities have declined sharply and the population has become more concentrated towards ...

The influence of environmental variables and mitigation measures on seabird catch rates in the Japanese tuna longline fishery within the Australian Fishing Zone, 1991–1995
Abstract: Long term fisheries observer data were used to analyse the influence of a range of ... environmental variables and mitigation measures upon catch rates of seabirds in the Japanese pelagic longline ... fishery. In the Australian Fishing Zone (AFZ) seabirds were most likely to be caught on longlines that ... were set during summer, in southern areas of the zone, and during daylight hours. However ...

Features of spatial and temporally distribution patterns of krill flux in the Scotia Sea: some comments on the development of a krill fishery management in Area 48.
Abstract: The spatial variability of krill flux in the Scotia Sea calculated by using the ... geostrophic method, is analysed. For this, CCAMLR-2000 international survey data was used. The analysis was ... carried out in the 0-500 m depth ranges 50 m layers. Water mass geostrophic circulation, spatial ... to the Scotia Sea, were a subject of study. It is clearly illustrated that the geostrophic krill ...
