Sockeye salmon smolts can undergo vast migrations without feeding. We explored relationships between deteriorating body condition and swim performance/survival. Most fish could not complete a swim challenge after 3 weeks without food, and after ~8 weeks, 50% had perished. Condition factor and energy density predicted swim performance and survival, respectively.
