Description

Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained. The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry.

Anthony Farrell

Tony Farrell is a graduate of Bath University, where he was fortunate to study with Peter Lutz. His fortunes grew further when he moved in 1974 to Canada and the Zoology Department at the University of British Columbia to complete his Ph.D. degree under the superb tutelage of Dave Randall. In 2004, Tony returned to UBC when he accepted an endowed research chair in Sustainable Aquaculture. In between these positions at UBC, Tony was employed at the University of Southern California (PDF), the University of New Brunswick (sessional lecturer), Mount Allison University (first real job) and Simon Fraser University (moving through the ranks to a full professor). In addition to highly controlled laboratory experiments on fish cardiorespiratory physiology, Tony is committed to working on animals in their own environment. Therefore, his research on fish physiology has taken him on an Alpha Helix expedition to the Amazon, the University of Gothenburg and the Kristineberg Marine Research Station in Sweden, the Portobello Marine Biological Station in New Zealand, the University of Christchurch and Massey University in New Zealand, the Bamfield Marine Science Station and the Huntsman Marine Station in Canada, the University of Aarhus in Denmark, the University of Adelaide Charles and Darwin University in Australia, and to the Danish Arctic Marine Station on Disco Island in Greenland. These travels have allowed him to work and with many superb collaborators word-wide, as well as study the physiology of over 70 different species of fish. Tony has received a number of awards for his scientific contributions: an honorary degree from the University of Gothenburg in Sweden; Awards of Excellence from the American Fisheries Society for Fish Physiology, Conservation and Management; the Fry Medal from the Canadian Society of Zoologists; and the Beverton Medal from the Fisheries Society of the British Isles.
