Species
- Common coral trout (Plectropomus leopardus)
Fish stock status
Although a species may be classified as sustainable under the Status of Australian Fish Stocks (SAFS) framework, this does not mean that the stock is meeting Queensland targets under the harvest strategy.

Stock assessment
The 2022 stock assessment used current biological data, survey data, and commercial and recreational catch data to:
- determine the sustainability of the stock
- help inform management decisions
- inform the application of the reef line harvest strategy.
The assessment estimated that the common coral trout stock was between 50% and 70% of unfished levels, and most probably at around 60%.
The assessment used Stock Synthesis, a modelling framework that was developed by the National Oceanic and Atmospheric Administration (United States).
