Rénald Belley, Biologist


Biologist mollusks

Current research and/or projects

I am biologist at Fisheries and Oceans Canada (Maurice Lamontagne Institute) working on mollusks (Sea Scallop, Icelandic Scallop and Stimpson's Surfclam). I am also interested in the role of benthic biodiversity on ecosystem functioning, and the impact of aquaculture and hypoxia on benthic communities.
