The collapse of Canada’s Atlantic cod populations in the early 1990s led to their designation as “endangered” and threatened the well-being of fishing people and the existence of rural communities. Less well publicized was the concurrent “crustacean explosion” – a big increase in populations of northern shrimp and snow crab which supported the highest values ever for Atlantic fisheries.  Are the cod coming back?  A story of massive ecosystem changes, out of sight below the surface of the sea.

Howard Powles has worked for more than 50 years on the biology of exploited marine populations and the dynamics of marine ecosystems, mostly for the government of Canada, more recently as a member of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and of expert panels assessing fisheries for eco-certification.

Monthly meetings are open to the general public.
