Abstract

Objectives: 1. Assess current data sources and their potential for estimating harvest rates and increases in efficiency in the western rock lobster fishery using change in ratio and index removal techniques. 2. Evaluate whether additional sources of information are needed to produce more robust estimates of harvest rate and efficiency increase. 3. Assess whether the estimates of harvest rate and fishing efficiency are reliable and could be used for the management of the western rock lobster fishery.
