Invasion of Asian Carp in the Great Lakes – Carpe Diem: A Fishy Tale with David Suzuki

Although Asian carp have yet to invade the Great Lakes, they are within 100kms of Lake Michigan and once established are difficult to remove and outcompete several native species which poses various economic and cultural problems. Asian carp species were accidentally introduced to the Mississippi River approximately 30 years ago and have established a population, while displacing several native species. CBC’s “The Nature of Things with David Suzuki”  recently aired Carpe Diem: A Fishy Tale investigates and explores the invasion and expansion of Asian carp throughout North America.  Suzuki delves into the history, basic biology and potential solutions to keep Asian carp out of the Great Lakes.

Lake Superior Warming “Faster Than Any Lake on the Planet”

Lake Superior, which is the world’s largest freshwater lake is currently experiencing warming rates that are faster than any other lake worldwide. Dr. James Kitchell, professor emeritus from the University of Wisconsin in Madison explains that increased warming is due to it’s size, 31 700 square miles, which allows it to absorb more solar radiation.  Over the past thirty years, Lake Superior has seen an increase in temperature by 6 degrees Fahrenheit.  Warming water temperatures have had various impacts, both positive and negative. Temperature increases have favoured the walleye populations causing an increase which provides an economic boost for recreational fisheries and associated businesses. Warming temperatures have also allowed for sea lamprey, an invasive species which has previously decimated lake trout populations, to make a comeback.
