Current research and/or projects

Debbie Martin-Robichaud has worked on environmental physiology of fish particularly as it pertains to aquaculture for many years and her recent focus is on marine fish reproductive physiology and broodstock development. Aquaculture diversification is a global trend and Canadian industries are striving to develop technology to culture new finfish species such as Atlantic halibut, Atlantic cod and haddock.

Ms. Martin-Robichaud strives to provide a base for industry development by maintaining pedigreed halibut, cod and haddock broodstock under optimal conditions, evaluating protocols to produce gametes out-of-season, developing innovative techniques and improving broodstock management technology, conducting experiments to address problems identified by industry, and by working closely with industry to train personnel and provide advice and expertise.

Debbie collaborates extensively with researchers at other institutions such as the University of New Brunswick and the NRC Institute of Marine Biosciences. Her recent research focus continues work on sex control in gadoids, examining final oocyte maturation processes in Atlantic halibut, cryopreservation of feminized milt from halibut and the application of molecular tools in marker assisted selection.
