Metabolic and Gill Physiology Data of Common Darter Fish in the Grand River, Ontario

This study aims to link changes in metabolism and gill physiology of the common darter fish (Etheostoma spp) to whole effluent toxicity in the Grand River, to better understand physiological compensation occurring in contaminated environments. This study will contribute to the necessary biomonitoring of fish populations, and overall Grand River health, through measuring changes to ecologically relevant physiological endpoints of multiple species. This data set is collected to support the project titled “Linking multiple stressors to adverse ecological response". This is a Pillar 1-2 project under the Global Water Futures Program funded by Canada First Research Excellence Fund.

The metabolism of rainbow, greenside, and fantail darters will be measured using intermittent flow respirometry, to determine aerobic scope and hypoxia tolerance. Gill physiological changes will be measured using histological analyses and enzyme assays relating to energetics. The sites of collection are near the wastewater treatment plant in Waterloo, Ontario. Two upstream, non-effluent receiving sites, and two sites at different distances from the effluent release downstream are considered. Sampling will be done, at least once, during spring, summer, and fall seasons.
