Now a species at risk, new research will inform eel rehabilitation and restoration projects
Outdoor Canada is pleased to present Blue Fish Radio—podcasts about the future of fish and fishing in Canada. The program, produced and hosted by Lawrence Gunther, is dedicated to sharing first-hand angling knowledge, scientific discoveries and supporting local champions who protect and enhance their waters.
The American Eel once dominated the Great Lakes and its many tributaries, at one time making up as much as 80% of the system’s biomass. Habitat loss, excessive commercial fishing and hydroelectric dams have all impacted the eel’s abundance, which is now estimated at about 1% of its former glory.
Every fall, Conrwall, Ontario’s River Institute carries out a nighttime survey (above) of American eels on the St. Lawrence River. In this episode, Matt Windle (below), a biologist with the River Institute explains how he and his volunteers carry out survey, and why it’s so important. Joining in to give her account on how the survey work unfolded is Blue Fish Canada volunteer Lisa Goodier.
