Sea Lamprey<\/h1>\nSea lampreys have been one of the most devastating invasive species to enter the Great Lakes. Over time, they\u2019ve contributed to the decline of native fish populations and threaten a multi-billion dollar <\/i>fishing industry. Using the sea lamprey as an example, this lesson explores how harmful non-native species can be and how expensive and complex it is to control an invasive species <\/b>once it is established.<\/p>\n

During a lamprey’s 18-month span as an adult, it will attach to a host fish with its suction-like toothed mouth, then suck nutrition out of the host fish, often killing it. The rapid decline in the number of native freshwater fish affects a Great Lakes sport and commercial fishing industry valued at almost $4.5 billion annually.<\/p>\n Biologists use a combination of methods to control the sea lamprey population in the Great Lakes.

Sea lampreys are eel-like fish that are native to the Atlantic Ocean. Since the 1830s, they have been migrating into the Great Lakes via Lake Ontario and the Erie Canal. Niagara Falls acted as a natural barrier for sea lampreys until the Welland Canal was improved in 1919. Once sea lampreys entered Lake Erie, they quickly spread to Lake Huron and Lake Michigan. In 1938, sea lampreys entered Lake Superior. Because sea lampreys attach to and feed on native freshwater fish, they have posed a serious threat to whitefish, lake trout and salmon during the past 50 years.<\/p>\nActivity<\/h2>\n

<\/b><\/a>Summary: <\/b>This board game teaches students about the various methods used to limit the sea lamprey population in the Great Lakes. Students assume the identity of sea lampreys and attempt to migrate from Lake Ontario to Lake Superior.
