It remains unclear if fishes that occupy Canada's leading tidal energy test site in Minas Passage, Bay of Fundy, Nova Scotia, will be negatively affected by turbine installations. The objective of this project is to determine fishes' interactions with operating turbines. Of approximately 70 species of fishes that interact with Minas Passage only three have abundance estimates (Gaspereau River Alewife; Shubenacadie River Striped Bass; Saint John River Atlantic Sturgeon) that are necessary to predict effects at the population level.
