This paper introduces the MEPS Theme Section (TS) ‘Comparative Analysis of
Marine Fisheries Production’. The unifying theme of the studies in the TS is the relative influence
of a ‘triad of drivers’—fishing, trophodynamic, and environmental—on fisheries production. The
studies were developed during 2 international workshops held in 2010 and 2011, which assembled
a database of fisheries, trophodynamic, and environmental time series from 13 northern
hemisphere marine ecosystems, and applied a common production-modeling approach to this
data. The studies encompass empirical examinations of the datasets, production models fitted to
the data at multiple levels of organization from single species to full ecosystems, and simulation
studies examining the impacts of climate effects and alternative management strategies on fisheries
production. The body of work presented in the TS demonstrates that using both production
modeling and the comparative approach together makes rapid progress towards ecosystem-based
fishery management, whether the aim is a better understanding of the ecosystem or the provision
of operational management advice.
