286 - Protecting Wetlands and Native Fishes from Common Carp at Delta Marsh with Paige Kowal of Ducks Unlimited Canada

The Fisheries Podcast

This week Paige Kowal from Ducks Unlimited Canada joins Brendan to talk about Delta Marsh, an over 18,000 hectare freshwater coastal wetland in Manitoba. Delta Marsh is important habitat to migratory birds, native fishes, and has been impacted by the introduced Common carp. Not only that, Delta Marsh has important cultural and economic connections to the region.

Over the last 50 years Ducks Unlimited Canada and other organizations have been experimenting with techniques and projects to protect the wetland. Paige discusses some of the history of this work, what the modern carp exclusion techniques look like, and the science the team is doing to showcase the recovery of the wetland, including protecting native species.
