34 JUNE 2021 • WORLD AQUACULTURE • WWW.WA S .ORG the voice saying “do not forget the seaweeds, one day you will see that they are important for many reasons” or “we need a session on seaweeds” at meetings for organizing aquaculture conferences. He has been attending conferences of the International Seaweed Association, the Phycological Society of America, and the Aquaculture Association of Canada since 1986, 1987, and 1991, respectively. He has been on the Board of Directors of each society for 12, 13, and 5 years, becoming the President of each. He also regularly presents at European Aquaculture Society andWorld Aquaculture Society conferences. He has been the scientific director of two large Canadian networks on Integrated Multi-Trophic Aquaculture (IMTA), an expression and acronym he first coined in October 2003. He created his own company, Chopin Coastal Health Solutions Inc., in 2016. He finds himself currently in a paradoxical situation: after promoting seaweeds for so many years, explaining the key roles, applications and services they provide, when it was not in fashion, he now has to put the brakes on and hold back a bit those with the urge to hug seaweeds (and sea cucumbers) as the planetary saviours, as professed daily on social media. Instead, he is advocating for a greener Blue Economy, the Turquoise Economy and the Turquoise Revolution (expressions he coined in September 2010), in which ecosystem services, provided by extractive aquaculture (seaweeds and invertebrates) are recognized, valued and used as financial and regulatory incentive tools through nutrient trading credits. This will lead to the progressive and pragmatic development of more diversified, efficient and societally responsible food (and non-food) production systems, within a circular economy approach, while performing bioremediation of coastal nutrification and transient decarbonization.
