Improved food consumption estimates as well as insights into the spatial and temporal relations between Atlantic cod and their prey are essential for ecosystem studies and management regimes. My thesis involves the development and testing of an empirically-based food consumption model for Atlantic cod in the southern Gulf of St. Lawrence. The research relies primarily on data concerning prey composition and weight estimates from stomach contents of Atlantic cod sampled in the field, along with size, sex, age, maturity, abundance, depth etc. estimates,
and with estimates of local oceanographic conditions (temperature, salinity, density, etc.). The unpublished stomach content and associated data have been collected seasonally by the Department of Fisheries and Oceans from 1990 to the present. My project also involves collecting estimates of the prey field (both size distribution and energy content) in situ and concurrent with the collections of cod in order to provide new insights regarding prey availability, electivity and selectivity and the spatial and temporal associations between the prey species and their predator as well as the oceanographic environment. It is my intention to provide an end product (model) that could be used to predict how food consumption rates may vary with changes in the cod population and abundance, environmental conditions as well as future fishing pressures on cod prey populations.
