This report focuses on one of the primary target species for which biomass-based stock assessments are periodically undertaken - sea mullet (Mugil cephalus). The report also includes a recent stock assessment for yellowfin whiting (Sillago schomburgkii) due to concerns regarding substantial increases in catch relative to historic levels.
Status of stock(s)
The current stock level is considered to be acceptable, and the current level of fishing mortality is unlikely to deplete the stock to a level at which recruitment could be impaired. On the basis of the evidence provided, the sea mullet stock in south-west WA is classified as Sustainable.
Based on all available lines of evidence, the current risk level for sea mullet in south-west WA is estimated to be Medium, with current management measures considered to be maintaining the stock at an acceptable level.
The yellowfin whiting stock in south-west WA is classified as Sustainable.
Based on all available lines of evidence, the current risk level for yellowfin whiting in south-west WA is estimated to be Medium, with current management measures considered to be maintaining the stock at an acceptable level.
