Summary

The West Australian dhufish is a demersal fish species highly sought after by commercial and recreational fishers, but its stock is overexploited, requiring a 50% reduction in catch. Dhufish are long-lived and slow-growing, reaching 40 years of age, and recovery is likely to be slow. The current size limit means fish enter the fishery at 6-7 years old, but become vulnerable to capture at 3-4 years old. Annual recruitment is highly variable, especially in the southern extent of its distribution, making management challenging. The goal is to gather sufficient data to estimate future population biomass and apply methods like statistical catch-at-age models for stock assessments.
