ResearchI am involved in conservation aquaculture mainly for fish species of particular status (endangered, vulnerable, cultivated or fished) and commercial aquaculture that include sustainabily values to their practices (reduction of organic loads, feed efficiency, improved growth etc.). Species of interest: wolffishes; charrs; icefishes; nothothens. I have also many interest in macroalgae/seaweed culture of East of Quebec indigenous species, aquatic bioremediation (macroalgae biofiltration; sulfur based denitrification).QCBS studentsPrevious students (since 2009) Bernard-Antonin Dupont CyrPh.D.  Fanny HallotPh.D.  Mirelle Caouette HouleM.Sc.
