520	|aThe negative trend in marine survival of North American Atlantic salmon has persisted in spite of severely reduced commercial salmon fisheries. This document examines the significance of replacing YEAR, a simple metric vector that accounted for a significant proportion of the variation in recruitment of salmon, with annual population estimates of harp seals (Phoca groenlandica) in recruitment models of one-sea & multi-sea-winter salmon. Harp seals were investigated as a replacement for YEAR because of their increasing population and their estimated consumption of salmon in the Northern Gulf of St. Lawrence. Interaction of the seal population with the index of winter habitat area for salmon is also examined for significant contribution to explanation of the variance in recruitment.
