Strong patterns were estimated for pup mass and condition since 1980, indicative of changes in nutritional status. Positive correlations were obtained between pup mass and first-year survival and, more tenuously, between male minus female pup mass and annual pupping rate. Both these relationships may have utility for future population assessment.
