Studies of physiological mechanisms are needed to predict climate effects on ecosystems at species and community levels and to help scientists understand the drivers of climate change.
Feeding aquaculture in an era of finite resources

- Biology, EngineeringProceedings of the National Academy of Sciences
- 8 September 2009
Trends in fishmeal and fish oil use in industrial aquafeeds are reviewed, showing reduced inclusion rates but greater total use associated with increased aquaculture production and demand for fish high in long-chain omega-3 oils.
Differences in Thermal Tolerance Among Sockeye Salmon Populations

It is shown that cardiorespiratory physiology varies at the population level among Fraser River sockeye salmon and relates to historical environmental conditions encountered while migrating, and thermal optima for aerobic, cardiac, and heart rate scopes are consistent with the historic river temperature ranges for each population.
The effect of temperature on swimming performance and oxygen consumption in adult sockeye (Oncorhynchus nerka) and coho (O. kisutch) salmon stocks

It is concluded that high-caliber respirometry can be performed in a field setting and that stock-specific differences in swimming performance of adult salmon may be important for understanding upstream migration energetics and abilities.
The determination of standard metabolic rate in fishes.

- Environmental ScienceJournal of Fish Biology

The main objective was to compare eight methods to estimate SMR and show that 12 h is insufficient but 24 h is adequate, and a list of basic recommendations for practitioners who use respirometry to measure SMR in fishes is provided.
Encyclopedia of fish physiology : from genome to environment
- A. Farrell, E. D. Stevens, J. Cech, J. Richards
- Environmental Science, Biology

This four volume encyclopedia covers the diversity of fish physiology in over 300 articles and provides entry level information for students and summary overviews for researchers alike.
From Hagfish to Tuna: A Perspective on Cardiac Function in Fish
- A. Farrell
- BiologyPhysiological Zoology
- 1 September 1991
A comparative view of cardiac physiology in fish is taken to provide insights into cardiac control mechanisms and the degree of cardiac plasticity between species to act as a framework for future research.
Excess post-exercise oxygen consumption in adult sockeye (Oncorhynchus nerka) and coho (O. kisutch) salmon following critical speed swimming
- C. G. Lee, A. Farrell, A. Lotto, S. Hinch, M. Healey
- Environmental ScienceJournal of Experimental Biology
- 15 September 2003
The underestimate of non-aerobic swimming costs may require a reevaluation of the importance of how in-river barriers like rapids and bypass facilities at dams, and year-to-year changes in river flows and temperatures, affect energy use and hence migration success.
Comparisons of swimming performance in rainbow trout using constant acceleration and critical swimming speed tests
- A. Farrell
- Environmental Science
- 1 February 2008
Umax was insensitive to a range of acceleration rates that differed by more than three-fold, and test duration could be reduced from 58 to 18 min without affecting the estimate of Umax, so swim tests that are appreciably shorter in duration than a ramp-Ucrit test result in Umax being appreciably greater than Ucrit.
Repeat swimming performance of mature sockeye salmon following a brief recovery period: a proposed measure of fish health and water quality
- K. E. Jain, I. K. Birtwell, A. Farrell
- Environmental Science
- 1 August 1998
Measurements of swimming ability, such as critical swimming speed (Ucrit), have commonly been used as indicators of the effects of environmental challenges on the general health of fish. In this…
