- Temperature has a reduced effect on routine metabolic rates of juvenile shortnose sturgeon (Acipenser brevirostrum)James D Kieffer
Department of Biology and MADSAM Sturgeon Physiology Lab, University of New Brunswick, Saint John, NB, E2L 4L5, Canada
Fish Physiol Biochem 40:551-9. 2014..These results suggest that juvenile shortnose sturgeon are sensitive to temperature changes at the lower end of the range, and less sensitive in the mid-to-upper temperature range. ..
- The effects of low-speed swimming following exhaustive exercise on metabolic recovery and swimming performance in brook trout (Salvelinus fontinalis)James D Kieffer
Department of Biology, University of New Brunswick, Saint John, New Brunswick E2L 4L5, Canada
Physiol Biochem Zool 84:385-93. 2011..g., lactate, osmolarity, glucose). These observations suggest that metabolic recovery and subsequent swimming performance may not be directly linked and that other factors play a role in swimming recovery in brook trout...
- The effects of temperature on the physiological response to low oxygen in Atlantic sturgeonJames D Kieffer
Department of Biology, University of New Brunswick, Saint John, NB, Canada
Fish Physiol Biochem 37:809-19. 2011..Overall, these findings suggest that Atlantic sturgeons are relatively tolerant to short-term and severe hypoxic stress, and the strategies for hypoxia tolerance may be temperature dependent...
- Behaviour and performance of juvenile shortnose sturgeon Acipenser brevirostrum at different water velocitiesJ D Kieffer
Department of Biology, University of New Brunswick, Saint John, N B, Canada
J Fish Biol 74:674-82. 2009..When present, these behavioural responses are probably related to morphological features, such as flattened rostrum, large pectoral fins, flattened body shape and heterocercal tail, and may be important to reduce the costs of swimming...
- Oxygen consumption, ammonia excretion and protein use in response to thermal changes in juvenile Atlantic salmon Salmo salarJ D Kieffer
Department of Biology and Canadian Rivers Institute, University of New Brunswick, St John, N B, Canada
J Fish Biol 74:591-603. 2009..salar. These results indicate that both the magnitude and the rate of temperature change are important in describing the physiological response in juvenile salmonids...
- Perspective--Exercise in fish: 50+years and going strongJames D Kieffer
Department of Biology and Canadian Rivers Institute, University of New Brunswick, Saint John, N B E2L 4L5, Canada
Comp Biochem Physiol A Mol Integr Physiol 156:163-8. 2010..As part of the 50th Anniversary of Comparative Physiology and Biochemistry, this perspective examines the history of fish exercise research, and some of the individuals who have made significant contributions...
- The effects of dissolved oxygen and triploidy on critical thermal maximum in brook charr (Salvelinus fontinalis)Lauren E Ellis
Department of Biology, University of New Brunswick, P O Box 4400, Fredericton, E3B 5A3 New Brunswick, Canada
Comp Biochem Physiol A Mol Integr Physiol 166:426-33. 2013..Indices of the secondary stress response (plasma glucose and ions) during CTMax tests under hypoxia responded as would be predicted for an acute stress, with no difference between triploids and diploids. ..
- Persistent effects of incubation temperature on muscle development in larval haddock (Melanogrammus aeglefinus L.)D John Martell
Fisheries and Oceans Canada, St Andrews Biological Station, 531 Brandy Cove Road, St Andrews, NB, E5B 2L9, Canada
J Exp Biol 210:1170-82. 2007..The muscle developmental and growth strategy as indicated by sequential changes in cellularity and cell-size distributions between myotomes in response to temperature are also discussed in light of whole animal growth and development...
- The effects of an acute temperature change on the metabolic recovery from exhaustive exercise in luvenile Atlantic salmon (Salmo salar)Brendan J Galloway
Department of Biology and Centre for Coastal Studies and Aquaculture, University of New Brunswick, Saint John, New Brunswick E2L 4L5, Canada
Physiol Biochem Zool 76:652-62. 2003..However, the relationship between behavioural thermoregulation and recovery following exhaustive exercise in fish is not well understood...
- Exhaustive exercise and the cellular stress response in rainbow trout, Oncorhynchus mykissKathleen Clarkson
Department of Biology, Mount Allison University, Sackville, NB, Canada E4L 1G7
Comp Biochem Physiol A Mol Integr Physiol 140:225-32. 2005..Our results indicate that hsp70, hsp30, and hsp90 are not part of the early recovery process from burst exercise in fish, perhaps due to the maintenance of core temperatures as well as a lack of exercise-induced tissue damage...
