Can multispecies models be expected to provide better assessments for Celtic sea groundfish stocks?

But is this always true? By considering a case-study based on Celtic Sea groundfish stocks, we review the biological processes and interactions and determine whether data and understanding of these processes is adequate for successful incorporation into a more complex management tool. Our approach is to determine what such a multispecies model need look like in this situation, and then to consider the expected performance of such a model based on preliminary results from a simplified food-web and literature studies.
