Abstract :	Most previous studies examining growth and survival of fishes have focused on population-level phenomena. In this study we use an individual-based approach to examine the mechanisms regulating growth and survival of Atlantic salmon. Our goal is to assess the relationship among growth, survival, habitat choice, maturation and migration timing of individual juvenile Atlantic salmon in three different watersheds of the Connecticut River basin. Our specific objectives are to 1) establish growth trajectories by resampling individual juvenile salmon; 2) compare growth trajectories of individuals within and between year classes among streams and years; 3) assess relationship among individual growth trajectories, subsequent growth, survival, habitat choice, maturation and migration timing; 4) evaluate extent of site fidelity of individuals; 5) conduct monthly mark-recapture population estimates during spring, summer and fall for two years; and 6) develop a mechanistic model of juvenile salmon growth.
