TAGS
This project reports on:
1) our detailed evaluation of current methodologies for otolith chemical analysis, and our recommended procedures when electron probe microanalysis is used for stock delineation in finfish
2) our assessment of the accuracy and precision of otolith probe microanalysis relative to the scales of natural variability in otolith composition, and an evaluation of the extent to which such variability reflects changing environment conditions
3) a direct test of the hypothesis that SE Tasmanian bays are the sole nursery area for Jackass Morwong
4) an evaluation of the likelihood of more than one spawning area/migration route for southern Bluefin Tuna.
