The terms of reference (C. Res. 1990/2:5:27) are:a) continue the development of multispecies methods of assessment;b) consider how to better incorporate predation on and by o-group fish in quantitative models of interspecies predation, particularly with regard to data to be collected in the 1991 Stomach Program;c) conduct medium and long-term stochastic simulations incorporating multispecies effects, with emphasis on functional feeding relationships and stock/recruitment relationships;d) explore the utility of various population attributes for comparing underlying trophic mechanisms among exploited ecosystems;e) continue the development of multispecies models for Arctic/boreal ecosystems, focusing on problems of joint management of interacting species;f) conduct statistical analyses of the underlying relationships in Arctic/boreal ecosystems of cod growth to prey abundance and environmental variability, focusing on time-series data concerning:i) cod growth increments,ii) population abundance of cod and its ...
