Multispecies modelling is an essential part of the NAFO roadmap for an Ecosystem Approach to Fisheries management, connecting the “Ecosystem” tier with the “Single species” tier. Aware of the importance of continue moving forward in this direction, the EU DG-MARE launched in 2017 the project SC05 “Multispecies Fisheries Assessment for NAFO” with the intention of identifying the potential alternatives to implement an multispecies approach in NAFO, with the Flemish Cap as a case study. As part of this project the multispecies model GadCap, considering the Flemish Cap cod, redfish and shrimp interdependent dynamics over the period 1988-2012, has been improved and extended until 2016. This working document describes the improvements in relation to the version delivered in 2016, and present diagnostic figures to assess the fit of the model to the different databases. Finally, model estimates of population abundance, biomass as well as the predation and fishing mortality are presented |
