1. Development of a spatially-explicit minimum realistic model for Antarctic toothfish (Dissostichus mawsoni) and its main prey (Macrouridae and Channichthyidae) in the Ross Sea

   Abstract:  To explore the potential effects of the toothfish fishery on the population dynamics of ... spatially explicit model using a predator-prey suitability model for the Ross Sea Region. We model the age ... predation mortality (M2), in addition to fishing mortality (F) on all three species. The model suggests that ... the predation release caused by the fishery effect on toothfish abundance is greater than the direct ...

7. Preliminary assessment of the South Georgia ray populations

   Abstract:  We modelled the ray population at South Georgia using a surplus production model ... implemented in a Bayesian framework. Catch and CPUE data were reconstructed for the time series 1985 – 2006 ... from a variety of sources, and included the consideration that since 2004 the practice of cutting rays ... off lines at the water surface should have increased survivorship of discarded rays, although this ...
