- ... Following interactions with fisheries gear, fishes may experience delayed mortality or display modified behavior. The physiological status of fish at the time of capture, including the presence of infectious agents, can also influence survival outcomes. To explore the relationship between capture, infectious agents and fate, we simulated gillnet capture on adult salmon returning to a hatchery, use ...

- ... Dorsal muscle and adipose fin samples collected from sockeye salmon (Oncorhynchus nerka) on the spawning grounds were used to investigate the dependence of tissue stable isotope values (δ13C and δ15N) on population origin and sex. Tissue stable isotope values differed by sex in all populations, presumably due to differences in male and female energy use during migration. Population origin had no e ...
