Integrative biology professor Robert Hanner‘s opinon piece on fish fraud was featured recently in The Globe and Mail for World Oceans Day. Hanner, associate director of the Canadian Barcode of Life Network, discussed the prevalence of fish fraud, or product mislabelling and adulteration, in Canada. He said fish fraud is destroying our oceans because it is driven by unsustainable fishing practices. Hanner said consumers need to demand more information, including the type of fish, where it came from and how it was harvested. He said technologies such as Guelph-developed DNA biotechnology help verify authenticity, but consumers need to speak up for sustainable fishing.
