Key research

  • Alex Hesp - Development of a more rigorous approach to estimating both the natural and total mortality of finfish species. A modification of the von Bertalanffy growth curve to accommodate those cases where the overall growth curve does not describe adequately the growth of a species when that species undergoes a length-dependent movement offshore.
