In the present study, we use Ecopath and inverse methods to reconstruct trophic flows through the whole northern Gulf of St. Lawrence ecosystem (NAFO zones 4RS) for the mid-1990s period, prior to the groundfish stock collapse. This was a period of relatively constant biomass for the major species. The whole-system model of the northern Gulf of St. Lawrence is divided into 32 functional groups or compartments from phytoplankton and detritus to marine mammals and seabirds, including harvested species of pelagic, demersal, and benthic domains. We present here details of the input data (biomass, production, consumption, export, and diet composition) for each compartment used for modelling. the successful development of ecosystem models proposed by the Comparative Dynamics of Exploited Ecosystems in the Northwest Atlantic (CDEENA) program will provide powerful new tools to evaluate the impact of human and environmental factors on a variety of Atlantic shelf ecosystems.

The Fisheries Oceanography Committee (FOC) of the Department of Fisheries and Oceans (DFO) met in Mont-Joli, Québec, at the Maurice Lamontagne Institute on 17-19 March, 1999. The Committee reviewed environmental conditions in the Northwest Atlantic during 1998, held a theme session on the lower trophic levels in the marine ecosystems of the Northwest Atlantic, discussed the Zonal Monitoring Program and its linkages to the FOC, reviewed additional papers on physical and biological oceanography and on cod recruitment and growth, and conducted its annual business meeting.
