Abstract
Summary Objective: Run exisiting species and size-based models in parallel, using common input data, in order to establish which are the best-suited to answering particular fisheries management questions. Evaluate problems encountered when applied to case study-specific management scenarios, and evaluate the relative strengths and weakness of each approach. The project will focus on two case study regions (i) the North Sea, and (ii) the `western-approaches`. Key Customer Purpose: Test and critically evaluate the usefulness of different modelling approaches for exploring wider ecosystem considerations of fisheries in the marine environment. Assess how important the interactions are between predators and their prey in comparison with other sources of uncertainty in fisheries models, and help to predict knock-on, ecosystem implications of future management actions.
