MSc Opportunity in Fish Physiology (2021-2023)
We seek an independent, motivated student for an MSc position at the University of New Brunswick to study how triploidy affects hypoxia tolerance and metabolism in fish, to be co-supervised by Dr. Tillmann Benfey (Fredericton campus) and James Kieffer (Saint John campus). Triploids are sterile and therefore have potential value in aquaculture, but they are rarely used because they are less robust than diploids when challenged aerobically. Both our labs study fish metabolism but from different perspectives, providing excellent training opportunities in basic and applied biology. While the principal study species would be brook trout, there would be opportunities to study Atlantic salmon, Arctic charr or zebrafish as well, using aquatic facilities at either campus. The position will begin in either May or September 2021, with the student officially registered on the Fredericton campus but undertaking research in our labs on both campuses.
Applications should include a brief statement of interest, resume, unofficial transcript, and the name and email address of two referees who can comment on your suitability for graduate studies in this field. To apply, or for any questions, please contact either or both of us:

WELCOME TO THE MADSAM STURGEON ECO-PHYSIOLOGY LAB
The MADSAM Sturgeon Eco-physiology Laboratory (UNB Saint John) involves researchers who share a common interest in understanding the biology, behaviour and physiology of east-coast sturgeon species. Since 1998, our lab has been working on Shortnose and Atlantic Sturgeon research projects that have focused on swimming metabolism as well as salinity, temperature and hypoxia tolerance. Our overall goal is to understand energy expenditure and metabolic needs for these species in dynamic environments.

Dr. Jim Kieffer joined the University of New Brunswick in 1996 as an assistant professor. Prior to his arrival at UNB, Kieffer was a research post-doctoral fellow at McMaster University (Chris Wood), where he worked on metabolic fuel use patterns in rainbow trout and tilapia. Kieffer obtained his undergraduate (1988 and 1989) at U of Ottawa, and Master’s (1991) and Ph.D. (1995) degrees at Queen’s University (Canada). His Ph.D. focused on the effects of body size and temperature on the physiological response to exercise in trout and bass. Kieffer’s work also focused on the biological effects of catch and release angling. This work has taken him to Atlantic Canada, and to lakes within Ontario and Quebec. His current research is entirely devoted to Shortnose and Atlantic sturgeons. He and his students work on aspects of thermal and salinity tolerance, exercise, metabolism and stress in sturgeon. Kieffer has published extensively on the effects of temperature on physiology and swimming in sturgeon. He and his collaborators have given over 100 presentations at conferences around the world on topics related to temperature, exercise, and metabolism in fish. He has served as a regular peer reviewer for several journals, Fish Biology, Journal Applied Ichthyology,Comparative Biochemistry and Physiology, JEB and Canadian Journal of Zoology.
His research is funded by NSERC, NBIF and UNB.
