Abstract

The Queensland east coast Ballot’s saucer scallop (Ylistrum balloti, formerly Amusium balloti) is a marine bivalve mollusc with a hinged shell. They are mainly found between 22 degrees South and 27 degrees South in shelf water depths of 20 to 60 metres. Saucer scallops can potentially grow to about 12 to 14 cm in shell height and, in some instances, live for up to 4 years. Scallops generally mature between 11 and 18 months of age.

This stock assessment indicates that biomass declined between 1956 and 2016 to 10% unfished biomass. In 2022, the stock level was estimated to be 15% unfished biomass (95% confidence interval 10–25%).
