Why did we assess the common coral trout stock?
In 2022, Fisheries Queensland completed the fourth stock assessment of the east coast common coral trout stock. It used the most 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.
This assessment estimated that the common coral trout stock was between 50% and 70% of unfished levels, and most probably at around 60%.
How was the stock assessment conducted?
The 2022 assessment used a stock assessment model called Stock Synthesis, one of the most widely used and tested stock assessment models in the world. It is currently used by CSIRO and other Australian fisheries jurisdictions.
Next steps for fishery management
Under the Queensland Harvest Strategy Policy and Reef Line Harvest Strategy 2020–2025 , management strategies are applied to keep stocks above the limit reference point (20% biomass) and set a target reference point to manage stocks toward.
The Reef Line Fishery working group provides advice on the operational aspects of the management of the fishery. The working group includes representatives from commercial, recreational and charter sectors; seafood processors and wholesalers, Indigenous representatives and the conservation sector.
