The purpose of this project was to address the constraints to management and development arising from the use of uncertain estimates of total mortality in stock assessments incorporating analytical fishery models such as yield per recruit. Through management strategy simulations, the project demonstrated that the use of age-based methods of total mortality estimation (using catch-curves based on age frequency distributions) in the estimation of current fishing mortality led to improved management performance. Guidelines for the management of demersal tropical fisheries were developed. This final report outlines the project's goals, methodology, results and guidelines developed.
