Most barriers allow jumping fish to pass with minimal disruption. 2.2 Barriersīarriers have been constructed to block the upstream migration of spawning-phase sea lampreys. ![]() Photo credit: Fisheries and Oceans Canada. Despite the success of TFM and granular Bayluscide, lampricides are costly and the Great Lakes Fishery Commission is seeking to reduce their use by relying more on the following alternative methods.įisheries and Oceans Canada and the US Fish and Wildlife Service staff carrying out sea lamprey control on the Great Lakes. Environmental Protection Agency and with Health Canada.Ībout 200 Great Lakes streams are treated at regular intervals with lampricides to kill larval sea lampreys. TFM and granular Bayluscide are registered with the U.S. A solid form of lampricide, known as granular Bayluscide, is applied to slow-moving or deep waters. It is not harmful to humans or other mammals at the concentration applied. After extensive testing, which began in the 1950s, scientists determined that TFM is non-toxic or has minimal effects on aquatic plants, invertebrates, fish, and wildlife. TFM kills sea lamprey larvae in streams with little or no impact on other fish and wildlife. This assessment data is then used to help the commission decide which streams to treat with lampricides.Ĭurrently, the primary method to control sea lampreys is a lampricide called TFM. Sea lamprey control begins when biologists go into the field and determine which streams contain sea lamprey larvae. By the early 1960s the catch was only about 136,000 kgs. (15 million lbs.) of lake trout in lakes Huron and Superior annually. For example, before sea lampreys entered the Great Lakes, Canada and the United States harvested about 7 million kgs. This contributed significantly to the collapse of fish species that were the economic mainstay of a vibrant Great Lakes fishery. In the 1940s and 1950s, sea lamprey populations exploded as there were no effective control methods and no natural predators. Sea lampreys prey on all types of fish, such as lake trout, salmon, rainbow trout (steelhead), brown trout, whitefish, yellow perch, burbot, walleye, catfish, and even sturgeon. Sea lampreys are so destructive that, under some conditions, only one out of seven fish attacked will survive. A single sea lamprey will destroy up to 18 kgs (40 lbs.) of fish during its adult lifetime. They attach to fish with their suction mouth and teeth, and use their tongue to rasp through a fish’s scales and skin so they can feed on its blood and body fluids. Sea lamprey control is one area where we are winning the battle. Through stewardship and cooperation, we are tackling some of our biggest challenges. The health of the Great Lakes fishery is under constant threat from habitat loss, pollution, and invasive species including sea lampreys. The fishery alone generates up to $7 billion for the region annually, offering recreational angling opportunities for five million people and providing 75,000 jobs. More than 40 million people depend on the Great Lakes for food, drinking water, and recreation. The Great Lakes are a valuable resource shared by Canada and the United States.
