Abstract

This project undertook analyses to understand the roles of overfishing and the environment on saucer scallops.
Results of this study indicated a decline in numbers of spawning scallops. High levels of fishing effort since the 1980s contributed to stock depletion. In addition, environmental influences such as increased sea surface temperatures (SST) may have amplified scallop mortality rates.
These findings can be applied to efforts for stock rehabilitation for the scallop fishery between Yeppoon and K’gari (Fraser Island). Recommended management actions include reduction of the spatial intensity of fishing effort applied, and ensuring sufficient annual spawning to support the scallop population and fishery.
