Development of methods for evaluating the management of benthic impacts from longline fishing using spatially explicit production models, including model validation
Abstract: An important management objective for CCAMLR in the high seas region of the Antarctic ... extreme case studies to validate the underlying model and code. In general, the model simulations were ... that they are relatively simple to construct, run, and interpret. In most cases, the results of the ... simulations suggested that management action of areal closures in the Ross Sea region are likely to result in ...

Modelling the impact of krill fishing on seal and penguin colonies
with the foraging area of land-based predators such as seals and penguins in the Antarctic Peninsula ... region. The dynamics of krill in this region are strongly influenced by advective processes. A key ... predator colonies. In order to estimate the krill production actually available for predator consumption ... , it is necessary not only to consider “snapshot” survey estimates of krill abundance in the vicinity ...
