All NMU Master's Theses
Brook trout (Salvelinus fontinalis) is a cold-water species with a narrow range of thermal tolerance. Climate change projections show that in addition to increases in average temperatures worldwide, daily thermal variability is increasing. Such conditions could prove challenging for brook trout and other ectotherms that are adapted to small temperature ranges. This research investigates how the growth and metabolic capacities of brook trout respond to long-term exposure to thermal variation. Groups of fish were reared under three thermal regimes: constant baily temperature, a 4°C daily range, and an 8°C daily range in a controlled lab setting. This was …
