Modelling the Irish Sea food web in the context of a depleted commercial fish community
The goal of my project is to utilise ecosystem and multi-species modelling techniques to investigate the dynamics of the food web based around the commercial fish species in the Irish Sea.
Despite large reductions in fishing effort, the management of Irish Sea fisheries is currently challenged by a lack of recovery in commercial fish populations with significant changes in growth rates, productivity and maturity for various species.
We will use ecosystem models to determine the explanatory factors underpinning the recovery failure in the Irish Sea commercial fish stocks, and to propose mitigating management actions on the basis of these findings.
This project contributes towards the goals of the ICES Irish Sea working group.
