Information Common Name: Sea Lamprey Why is it a concern?
How does it spread? Pros/Cons Pros: helps keep the population of it's favorite fish to feed off of from getting to big. Ways to control
it Lampricides: TMF kills sea lamprey larvae in streams with little or no impact on other fish and wildlife ("How")
Barriers: barriers have been constructed to block the upstream migration of spawning sea lampreys; most barriers allow other fish to pass with minimal disruption ("How")
Traps: Traps are designed to catch lampreys
as they travel upstream to spawn. They are
then used for research. ("How") Works Cited "How Are Sea Lampreys Controlled." How Are Sea Lamprey Controlled? N.p., n.d. Web. 04 Oct. 2012. <http://www.glfc.org/sealamp/how.php>. "Sea Lampreys, Petromyzon Marinus." At MarineBio.org. N.p., n.d. Web. 04 Oct. 2012. <http://marinebio.org/species.asp?id=542>. Cons: The host fish is often killed or seriously wounded. Under certain conditions, only one in every seven host fish will survive ("Sea") Lampricides Barrier Trap Habitat: sea lampreys live in the open ocean, migrating into freshwater to spawn. ("Sea") How they got here: They entered the Great Lakes through ship canals and locks ("USGS) Scientific Name: Petromyzon marinus ("Sea") "| USGS Great Lakes Science Center." | USGS Great Lakes Science Center. N.p., n.d. Web. 04 Oct. 2012. <http://www.glsc.usgs.gov/main.php?content=research_lamprey>. The Great Lakes contained several smaller, native lampreys, but the sea lamprey rapidly out competed them wherever their range overlapped ("USGS") Special modifications of their kidneys allows these species to live in either fresh or salt water ("USGS")
