Abstract
The characteristics used to identify 19 developmental stages of preserved eggs of snapper, Pagrus auratus, collected from Shark Bay, Western Australia, during annual plankton surveys, are described and illustrated. A key is provided to enable the age of each egg stage to be estimated based on sea surface temperature and salinity observed during sampling. This report is intended as a reference for inexperienced staff, to ensure that between-year comparisons of snapper spawning biomass, estimated using the daily egg production method, are based on consistent egg staging and ageing methods.
