摘要：This study was designed to develop a cost-effective system for obtaining estimates of the annual
age structure (or age composition: the relative abundance of each 1-year age-class) of exploited
fish stocks. The overall aim of the project was to reduce costs for individual stocks so that the
sustainability status of more stocks could be assessed within the constraints of available funding.
Biological databases for a variety of scalefish stocks, held at the Department of Fisheries, Western
Australia, and Murdoch University, were interrogated to determine which held information that
would allow examination of measures such as otolith weight or total length relative to ages
estimated using the more traditional technique of counting ¡°rings¡± on otoliths.
