UPDATED BIOLOGICAL PARAMETERS FOR THE ANTARCTIC STARRY SKATE, AMBLYRAJA GEORGIANA, FROM THE ROSS SEA
Abstract: Photographs of skates taken by observers on New Zealand toothfish longliners in the ... Ross Sea were identified to species. Sample sizes were small, but indicated a ratio of 10.75:1 of ... of tagged skates. Biological parameters were reviewed and updated for Amblyraja georgiana. Revised ... relationships differ significantly. Better estimates of median length at maturity were made possible through a ...

KPFM2, be careful what you ask for – you just might get it
the WG-EMM in 2005. The new version of our model is called KPFM2, and we have addressed all four of ... allocation of catch among the SSMUs (i.e., add seasonality, consider alternative movement hypotheses, add ... distribution of simulated catch to the distribution of historical catch). We have added a substantial number of ... other features to the model as well. Many of these features were suggested to us at the 2005 meeting of ...
