This project was developed in response to calls from the SBT Trilateral (now the CCSBT) Scientific Committee for the development and validation of techniques for the direct estimation of age and growth in the species. Since the early 1980’s, the stock assessment methods used by...
For this very new fishery, those aspects of the species' biology most relevant to its management and continued exploitation are its distributions, abundances and rates of growth. Unfortunately at the start of this project/ we knew none of this information for the NSW stock. As a first step I...
