Cardiac control in primitive fishes (hagfish): C. Wilson, Ph.D. candidate, is investigating cardiac control in the Pacific hagfish heart. These hearts have no neural input, and therefore the heart rate control mechanisms are unknown. Using realtime reverse-transcriptase PCR, pharmacology, electrophysiology, electrocardiogram and molecular biological techniques, it has been discovered that the pacemaker of the hagfish heart is governed by hyperpolarization-activated cyclic nucleotide-gated channels, the funny current, and that catecholamine and bicarbonate ions may be involved in regulation of that beating rhythm.
The Structure and Function of the Coronary Artery in Elasmobranchs:Ph.D. student G. Cox’s research focuses on how the coronary artery optimizes oxygen delivery to the elasmobranch heart under environmental and physiological stressors. Currently she is examining the structure and function of the coronary artery in a variety of shark species that vary in athleticism and habitat to determine if there are adaptations to the coronary artery that may be beneficial to exercise, and hypoxia and temperature tolerances.
Cardiac adrenergic sensitivity of Fraser River sockeye Salmon: Cardiac adrenoceptor density has recently been shown to differ among Fraser River sockeye Salmon populations. Such receptor density differences may manifest as differences in cardiac performance between these populations. M.Sc. Student A. Goulding is isolated cardiac muscle preparations to study the cardiac adrenergic sensitivity of upper and lower Fraser River sockeye Salmon.

Recent and Past Projects
Spawning migration of Pacific salmon and climate change: Elevated river temperatures during physically demanding spawning migrations have been repeatedly associated with adult mortality in Fraser River sockeye. Post-doc T. D. Clark investigated the energetic requirements of the migrating fish, while Ph.D. student E. Eliason tested the hypothesis that cardiac function becomes a limiting factor at high temperatures for these fish.
Triploidy and fitness in rainbow trout: Triploid fish are less tolerant of suboptimal environmental conditions (most remarkably high temperature), possibly due to their enlarged cell volume. Ph.D. student C. Verhille compared the cardiorespiratory physiology of diploid and triploid rainbow trout, and related it to swimming performance and survival.
Pink salmon & Sea lice project: Sea lice from salmon farms are often blamed for the collapse of the pink salmon runs in northern Vancouver Island, and few scientific studies had quantified how sea lice really affect pink salmon smolts. In collaboration with Dr. Colin Brauner of the UBC Zoology Department, we undertook an objective examination of the effects of lice loading on:
- Ontogeny of salinity tolerance in pink salmon (Z. Gallagher)
- The effect of seawater migration and sea lice infestation on metabolic rate and aerobic scope of pink salmon (A. Azzam)
- Swim performance of juvenile pink salmon (L. Nendick)
- Stress physiology of juvenile pink salmon (M. Gardner)
- Osmoregulation in juvenile pink salmon (M. Sackville)
- Growth and smoltification in juvenile pink salmon (A. Grant)
Stress and recovery during commercial fish transport: Commercially farmed salmon must be transported live from freshwater hatcheries to the saltwater farms, and often from the saltwater farm to the processing plant. M.Sc. student M. Nomura examined changes in plasma chemistry and schooling behaviour in smolts during transport, while a concurrent study by M.Sc. student S. Tang looked at changes in water quality to determine oxygen consumption and carbon dioxide tolerance in adult salmon, as well as final flesh quality.
Anoxia tolerance in reptiles and fish: Freshwater turtles living in temperate climates lie dormant at the bottom of ponds and lakes during the cold season. For his Ph.D. thesis, J. Stecyk examined cardiovascular function in anoxic and normoxic turtles, as well as similar traits in the surprisingly anoxia-tolerant Crucian carp.
Exercise physiology of fish hearts: Intense exercise results in changes, sometimes detrimental, to the extracellular fluids bathing the vertebrate heart. Former M.Sc. student and current lab manager L. M. Hanson used the perfused heart technique to investigate cardiac performance in rainbow trout and in African catfish during hypoxia, hyperkalemia and acidosis at different temperatures, as well as the stimulatory and protective effects of adrenaline.
Nutrition, gut blood flow and growth in rainbow trout: New developments and understanding of the digestive physiology of fish are desired for environmental, economical and scientific reasons. Former M.Sc. student E. Eliason simultaneously measured oxygen consumption, blood flow to the gastrointestinal system and heart rate in postprandial rainbow trout. Oxygen consumption was found to closely correlate with heart rate, which could lead to exciting new research using biotelemetry systems to indirectly monitor MO2. Furthermore, a novel technique to cannulate the hepatic portal vein of fish has been pioneered by E. Eliason in collaboration with researchers in Norway in order to assess nutrient uptake and gut function.
Fish Recovery Box: In collaboration with Dr. Rick Routledge and Dr. Patricia Gallagher of Simon Fraser University and gillnetter Jake Fraser we helped the Department of Fisheries and Oceans redesign a fish recovery box used by commercial fishermen. The recovery box is used to revive coho salmon inadvertently caught as by-catch during other fisheries openings. The newly designed box is highly effective and has drastically reduced coho mortality rates.
