Stock Assessment

Research

Wednesday, 27 October 2010 12:05

We develop better methods for estimating and modelling the biological parameters used in stock assessments, such as natural mortality, reproductive potential, and growth. We update biological parameters based on recent data. We also investigate the effects of alternative approaches on stock assessment results, and possible benefits of better data.
