海七鳃鳗（Petromyzon marinus）在20世纪30年代末进入三五大湖上游，并在20世纪40年代中期开始在休伦湖和密歇根湖以及20世纪50年代中期在上级湖急剧入侵鱼类种群。1950年，人们开始认真尝试控制这种寄生虫，在美国休伦湖海岸沿线沿着安装机械屏障，以阻止产卵。到1960年，五大湖的132条支流上安装了1952年开发的电屏障，但控制措施直到1958年之后才开始生效，当时使用了一种选择性毒物--杀七鳃鳗剂3-三氟甲基-4-硝基苯酚（TFM）--来消灭溪流中的七鳃鳗幼虫。在21年，1958年至1978年，1223处理的支流上三个湖泊与TFM完成了334流- 91在加拿大和243在美国。控制计划成功的证据很快就很明显：首先是减少了海七鳃鳗产卵运行，这是通过在选举中采取的成年人数量来衡量的。
Sea lamprey (Petromyzon marinus) entered the upper three Great Lakes in the late 1930s and began making sharp inroads into the fish stocks by the mid-1940s in lakes Huron and Michigan and the mid-1950s in Lake Superior. The first serious attempts to control the parasite began in 1950 with the installation of mechanical barriers along the United States shore of Lake Huron to block spawning runs. Electrical barriers, developed in 1952, were installed in 132 tributaries of the Great Lakes by 1960, but control measures did not become effective until after 1958, when a selective toxicant — the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) — was used to destroy larval lampreys in streams. In the 21 years, 1958–78, 1223 treatments of tributaries of the upper three lakes with TFM were completed in 334 streams — 91 in Canada and 243 in the United States. Evidence of the success of the control program was soon obvious: first by reduced sea lamprey spawning runs as measured by the numbers of adults taken at elect...
