Examining the Impacts of Whales on Commerical Fisheries

Project Overview:
Leah Gerber (Arizona State University, AZ, USA)
At the International Whaling Commission (IWC), a principle argument used by some pro-whaling countries to resume whaling has been that whales eat large amounts of fish and thus compete with humans for commercial fish catches. This project examines the scientific evidence for the assertion that commercial fisheries are negatively impacted by whales’ consumption of fish, focusing on the Caribbean and northwest Africa.
