Limits on performance and survival of juvenile sockeye salmon () during food deprivation: a laboratory-based study.

Long-distance migrations can be energetically demanding and can represent phases of high mortality. Understanding relationships between body condition and migratory performance can help illuminate the challenges and vulnerabilities of migratory species. Juvenile anadromous sockeye salmon () may migrate over 1000 km from their freshwater nursery habitats to estuary and ocean feeding grounds.
