Medium: by itself P/B can be confounded by other maturity altering forces on the system and may not show only the effects of fishing. Further, as a model-derived indicator it is reliant on the assumptions used to construct the underlying model and the data used to parameterise and initialise the model. This makes it unsuitable as a predictive indicator, but this does not prevent it from being an informative indicator, especially if it is part of a larger suite of indicators. Thus, as one of a set of indicators it may be useful for characterising ecosystems and how they change.
Current status and trends
...
Management objective/direction
...
Stakeholder/Public acceptability
Acceptability with stakeholders?
* by all stakeholder
* by the public
* understandable to the stakeholders
