All Australian abalone harvest strategies use empirical approaches that apply a weight of evidence approach that is generally not clearly codified. Differences in harvest strategy across jurisdictions lead to very disparate ways of setting catches, with some adjusting catch based on relative performance of indicators, while others assume a direct relationship between “catch per unit effort” and sustainable catch. This investment will assess each of the presently used harvest strategies to draw out their strengths and weaknesses in a common platform. The project will also develop Management Strategy Evaluation software code for use by different jurisdictions to test and review harvest strategies.
