4. 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 ...
