Another important element of the GBYP research plan is the development of a robust advice framework consistent with the Precautionary Approach. This requires also the use of new stock assessment methods that take into account the main sources of uncertainty and utilise the new data sets and knowledge provided by the GBYP. New data sets include, for example, historic catch and effort data, aerial surveys of spawning aggregations, the results of the biological studies and tagging of both juveniles and adults.
In order to evaluate novel approaches, the SCRS is developing a Management Strategy Evaluation (MSE) framework that includes a simulation or Operating Model. This will allow current and alternative assessment and advice frameworks to be evaluated with respect to their ability to meet multiple management objectives.
A GBYP Core Modelling MSE Group was established in Phase 4 and the Modelling Strategic Plan is regularly updated.
