Project title: Learning from success –development of a biological model to explain successful upstream fishway passage by sturgeon

Hydropower dams create barriers to fish passage for many migratory species throughout the world. Fish passage is commonly reinstated at these sites through installation of engineered structures collectively termed fishways. However fishways are often unsuccessful at passing numerous species, including sturgeons. This is a pertinent issue considering all members of this unique family undertake some form of migration to spawn in freshwater and many are threatened.

My research will focus primarily on sturgeon passage at a successful fishway: the Vianney-Legendre fishway on the Richelieu River in Quebec, Canada. Specifically I plan to examine the factors that contribute to attraction and passage efficiency of sturgeon at fishways, evaluate the behavioural characteristics of successful and unsuccesful migrants ascending a fishway, calculate the energetic cost of fishway passage for sturgeon and link biological information with a hydraulic model of the fishway to identify the shear forces that sturgeon are exposed to in areas of difficult passage. This is a collaborative project between Carleton University, the University of Alberta, Fisheries and Oceans Canada and Ministère des Ressources naturelles et de la Faune et du Québec.
