The foraging range of Adelie penguins – implications for CEMP and interactions with the krill fishery
Abstract: This paper presents a summary of the foraging locations of the Ad6lie penguin at 7 ... widely spaced locations along the coast of Eastern Antarctica between 55°E near Enderby Land and 175°E in ... the Ross Sea region. Birds feeding chicks regularly travel 100-120km offshore to the continental shelf ... and return with krill. The pattern of foraging is similar between sites. The potential for overlap ...

Using spatial population models to investigate the effects of a proposed Marine Protected Area on Antarctic toothfish in the Ross Sea region
they usually involve the displacement of fisheries, their design rarely takes into account the effect ... of that fishery’s displacement on the target fish population. We used a spatially explicit population ... model of Antarctic toothfish in the Ross Sea region to investigate the effects of a proposed MPA on the ... status of the toothfish population. This study indicates that the MPA design proposed in 2013 is likely ...

Possible options for the future management of the Antarctic krill fishery in Subarea 48.2
Abstract: We review the state of ecological knowledge for Subarea 48.2 and suggest that the ... development of any new management approach based on ecological indicators is limited by the current level of ... relevant ecological information. We propose that there is therefore an urgent need to improve the ... ecological knowledge base, but identify that this will take time. We conclude that if the krill fishery in ...
