Long-term effects of surgically implanted telemetry tags on the nutritional physiology and condition of wild freshwater fish
(Inter-Research, 2009-03-09)Little is known about the long-term consequences of surgically implanted telemetry devices on wild fish, as they are rarely recaptured. We used wild largemouth bass Micropterus salmoides as a model to evaluate the long-term ... -
Osmoregulatory, metabolic and nutritional condition of summer-run male Chinook salmon in relation to their fate and migratory behavior in a regulated river
(Inter-Research, 2011-06-01)We studied the migratory success of male summer-run Chinook salmon Oncorhynchus tshawytscha in the Puntledge River on Canada’s Vancouver Island over a 3 yr period using biotelemetry and non-lethal physiological biopsy. ... -
Physiological responses of three species of unionid mussels to intermittent exposure to elevated carbon dioxide
(Society for Experimental Biology, 2016-12-29)Freshwater systems are at risk owing to increasing carbon dioxide (CO2) levels, and one of the possible reasons for these elevations is the deployment of non-physical fish barriers to prevent invasive fish movements. Carbon ... -
Seasonal carryover effects of an experimental stressor in a wild teleost fish
(University of Chicago Press, 2010-10-08)Stress can have sublethal effects that are manifested either immediately or at spatial or temporal scales that are removed from the stress event (i.e., carryover effects). We tested whether a short-term elevation of plasma ... -
Spatial ecology of adult muskellunge (Esox masquinongy) in the urban Ottawa reach of the historic Rideau Canal, Canada
(EDP Sciences, 2010-07-19)The Rideau Canal in Canada was constructed in the 1800s to enable strategic military and commercial transport in eastern Ontario between Lake Ontario and the Ottawa River. Today, the Rideau Canal is managed by Parks Canada ... -
Swimming activity of migrating Chinook salmon in a regulated river
(Inter-Research, 2012-10-17)Adult Pacific salmon Oncorhynchus spp. have a fixed amount of energy available to fuel their freshwater spawning migration, so they must optimize their activity in a manner that conserves energy to ensure successful ... -
Tolerance to Hypercarbia Is Repeatable and Related to a Component of the Metabolic Phenotype in a Freshwater Fish
(The University of Chicago, 2017-07-14)Freshwater fish may be exposed to high levels of carbon dioxide (CO2) because of several actions, including anesthesia and high levels of aquatic respiration and potentially as the result of using high-CO2 plumes as a ...
