Abstract The Cheboygan River, Michigan, is the only tributary to the upper Great Lakes where sea lamprey (Petromyzon marinus) are known to complete their entire life cycle. The Upper and Lower reaches are separated by the Cheboygan Lock and Dam located about 2 km from Lake Huron. In the Upper River, the Pigeon, Sturgeon, and Maple Rivers provide nursery habitat for larval sea lamprey. Burt and Mullett Lakes provide feeding grounds for juvenile sea lamprey. Low levels of immigration from Lake Huron occur when adult sea lamprey bypass the lock and dam. Lampricide treatment in the Pigeon, Sturgeon, and Maple Rivers began in 1966 and 15 treatments have been conducted to date at a combined cost of $435,000 USD per treatment. Treatments may become more difficult due to recent dam removals in the Pigeon (2016) and Maple Rivers (2018) that expanded habitat available to valued fishes and sea lamprey. At present, the landlocked population is less than 200 spawning adults, and those adults are generally smaller and may spawn earlier in the spring than adult sea lamprey from Lake Huron. Frequency of sea lamprey-induced wounding on steelhead (Oncorhynchus mykiss) and northern pike (Esox lucius) in Mullett Lake is less than 5%. Given increasing challenges of lampricide treatment, efforts to test other means of control such as sterile male release technique is on-going. The Cheboygan River represents a microcosm of the Great Lakes and is useful for learning about sea lamprey ecology and testing controls that supplement lampricides and barriers.

五大湖缩影中海七鳃鳗（Petromyzon marinus）控制与生态的案例研究

摘要 密歇根州的切博伊根河是五大湖上游的唯一支流，已知海七鳃鳗 (Petromyzon marinus) 完成其整个生命周期。上下游由距离休伦湖约 2 公里的 Cheboygan Lock 和 Dam 隔开。在上游，鸽子河、鲟鱼河和枫树河为幼体海七鳃鳗提供了栖息地。伯特湖和马利特湖为幼年海七鳃鳗提供了觅食地。当成年海七鳃鳗绕过水闸和大坝时，休伦湖的移民数量就会减少。1966 年开始在鸽子河、鲟鱼河和枫树河进行 Lampricide 处理，迄今为止已经进行了 15 次处理，每次处理的总成本为 435,000 美元。由于最近在 Pigeon (2016) 和 Maple Rivers (2018) 的大坝拆除，扩大了有价值的鱼类和海七鳃鳗的栖息地，处理可能会变得更加困难。目前，内陆种群的产卵成鱼不足 200 只，与休伦湖的成鱼相比，这些成鱼一般较小，可能在春天早些产卵。海七鳃鳗在马列特湖的钢头鱼 (Oncorhynchus mykiss) 和北梭鱼 (Esox lucius) 上受伤的频率低于 5%。鉴于杀灭灯剂治疗面临越来越多的挑战，正在努力测试其他控制手段，如不育雄性释放技术。切博伊根河是五大湖的缩影，可用于了解海七鳃鳗生态学和测试控制措施，以补充杀灯剂和屏障。
