This project addressed some of the important information gaps identified during assessment workshops for Bight redfish and deepwater flathead. Improved stock assessments, which incorporate the latest biological parameters (size-at-maturity, fecundity and sex ratio), has lead to the setting of...
Typically abalone are found clustered into aggregations of many individuals along gutters and ledges that dissect the surfaces of the reefs they inhabit. Commercial abalone divers take advantage of this clustering behaviour and specifically target aggregations to minimise the time spent searching...
Information on spawning and larval recruitment processes of commercially important species in coastal waters in south-eastern Australian waters is provided based on four daytime surveys carried out on board the RV Franklin during the summer of 1997 (January-February and December) and the winter of...
The aims of the Lakes Entrance scallop work were threefold: to monitor the period and abundance of spat settlement at sites east and west of Lakes Entrance; to survey scallop grounds for the distribution and abundance of juvenile and commercial sized scallops; and to determine the growth rate of...
During the 3 years of the study, scallop spatfall was observed to occur over a short period (October-December) after the scallops had spawned in spring. Growth was rapid and scallops reached an acceptable harvestable size of 70mm within 16 months. Spatfall one year can therefore be related to...
