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 ... -based population dynamics of toothfish, grenadier, and icefish, and include natural mortality (M1) and ... of the nature of the interaction. Whilst this model is in a development stage, it provides a useful ... tool for evaluating potential impacts of the fishery on key prey species, and for assessing and ...
