A physiological comparison of three techniques for reviving sockeye salmon exposed to a severe capture stressor during upriver migration
Capture of fish in commercial and recreational fisheries causes disruption to their physiological homeostasis and can result in delayed mortality for fish that are released. For fish that are severely impaired, it may be desirable to attempt revival prior to release to reduce the likelihood of post-release mortality. In this study, male sockeye salmon (Oncorhynchus nerka) undergoing their upriv...
متن کاملConservation physiology in practice: how physiological knowledge has improved our ability to sustainably manage Pacific salmon during up-river migration.
Despite growing interest in conservation physiology, practical examples of how physiology has helped to understand or to solve conservation problems remain scarce. Over the past decade, an interdisciplinary research team has used a conservation physiology approach to address topical conservation concerns for Pacific salmon. Here, we review how novel applications of tools such as physiological t...
متن کاملElectromyogram Telemetry, Nondestructive Physiological Biopsy, and Genetic Markers: Linking Recent Techniques with Behavioral Observations for the Study of Reproductive Success in Sockeye Salmon Mating Systems
Sockeye salmon Oncorhynchus nerka cease foraging before entering freshwater (Brett 1995; Hinch et al. 2006), so they must complete migration, develop gonads and secondary sexual characters, and spawn using stored energy. Research examining energy use by sockeye salmon during upriver spawning migrations (Brett 1995; Hendry and Berg 1999; Crossin et al. 2004) has revealed that successful migrants...
متن کاملLow cardiac and aerobic scope in a coastal population of sockeye salmon Oncorhynchus nerka with a short upriver migration.
This study showed that a coastal population (Harrison) of Fraser River sockeye salmon Oncorhynchus nerka had a lower aerobic and cardiac scope compared with interior populations with more challenging upriver spawning migrations, providing additional support to the idea that Fraser River O. nerka populations have adapted physiologically to their local migratory environment.
متن کاملObservable impairments predict mortality of captured and released sockeye salmon at various temperatures
Migrating adult sockeye salmon frequently encounter commercial and recreational fishing gear, from which they may be landed, escape or be intentionally released. In this experiment, migratory adult sockeye salmon were exposed to simulated capture-release in fresh water, including 3 min of exhaustive exercise and 60 s of air exposure at three ecologically relevant water temperatures (13, 16 and ...
