3. OTOLITH CHEMISTRY INDICATES POPULATION STRUCTURING BY THE ANTARCTIC CIRCUMPOLAR CURRENT

   population structure through the advection of life stages of marine fish species. To test this, we compared ... the Antarctic and between some Antarctic areas. We also found evidence of four groups of fish with ... different early life chemistry: one associated with South America and three Antarctic groups showing mixing ... consistent with advective transport along the ACC. These results suggest that toothfish populations are ...

4. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

   Abstract:  A new method for estimating illegal fishing effort is put forward. The results from ... this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ... detections and can potentially better handle the evasion of detection by illegal activity. Both the new and ...
