Swarm characteristics of Antarctic krill Euphausia superba relative to the proximity of land during summer in the Scotia Sea
Abstract: We studied the relationship between the proximity of land and the distribution and ... swarming characteristics of Antarctic krill across the Scotia Sea in January and February 2003. Krill ... -sectional areas of swarms were significantly larger inshore, with a mean value of 120 m 2 in the 0 to 50 km ... zone compared to <80 m 2 further offshore. The packing concentration of krill within inshore swarms ...

How precautionary is the policy governing the Ross Sea Antarctic toothfish (Dissostichus mawsoni) fishery?
Abstract: This article reviews the adequacy of data and models currently being used to estimate ... the present and future population sizes of the Antarctic toothfish (Dissostichus mawsoni Norman) in ... the Ross Sea regional ecosystem. It argues that the current tagging program is unlikely to provide an ... accurate picture of total population size, and that estimates of both the pre-exploitation spawning stock ...

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 ...
