The global potential biomass and production of fisheries can be estimated from simple models that combine macroecology, life-history theory and food-web ecology with primary production (PP) and temperature data from satellite observations (Jennings et al. 2008). For productive shelf seas, such as Georges Bank and the North Sea, this approach may underestimate the potential fisheries biomass and productivity due to a number of factors including those which influence the reliability of the PP estimates (e.g. phytoplankton growth and production in sub-surface waters).
For the North Sea a number of approaches have been adopted to improve the estimates of PP used as input to these models. These include combining observations from SmartBuoys, satellites, Ferryboxes, and field measurements of photosynthetic activity (from PAM and FrrF fluorometers, and 14C incubations) with ecosystem models. A 3D hydrodynamic model (GETM) coupled to a biogeochemical flux model (BFM) is being linked to a size-based fish ecology model to predict the potential biomass, production, size structure and trophic structure of consumer communities. Observations are used to validate the models, which consider horizontal transport and vertical exchange with the benthic compartment. Validated maps of production for the North Sea will be made available via the EMECO portal (www.emecogroup.org/).
