Abstract

The West Australian dhufish is a demersal fish species that is highly sought after by commercial and recreational fishers in the West Coast Bioregion of WA. An assessment of the stock status in 2009 by the Department of Fisheries indicated the stock was overexploited with a need for a 50% reduction in the overall catch. As the species is long lived and slow growing, reaching a maximum age of 40 years of age, the recovery is likely to be slow.
