4. Net sample validation of acoustic techniques used to identify and size Antarctic krill

   Abstract:  Acoustic surveys to estimate krill biomass require that sound backscattered by krill be ... collected with an RMT8. Around 80 % of the targets thought to be krill on the basis of their appearance on ... frequency data and compared with that obtained in net hauls. This comparison revealed that a simplified bent ... sampling characteristic types of acoustic target with nets. More recently partitioning of backscatter into ...

5. On the consequences of differentiating between adult and sub-adult survival rates in the krill-predators model

   . This solution brings with it new problems, however, in that two further parameters need to be specified ... -adult survival rate can be adjusted to ensure that the modelled predator population reflects observed ... adults and sub-adults, with different survival rates for these two groups. Broadly speaking, the sub ... for both these parameters, consideration needs to be given to the possibilities for qualitatively ...
