Beginning with the first lampricide treatments of Lake Huron streams in 1960, applying lampricides and maintaining barriers to migration in Lake Huron tributaries continue to be the primary methods of controlling sea lampreys (Petromyzon marinus). In years leading up to the new millennium, sea lamprey abundance in Lake Huron remained at high levels, yet well below the pre-control adult abundance estimate of 700,000 adults. Two decades later, a variety of sea lamprey control strategies have been developed and employed to further reduce sea lamprey abundance in Lake Huron. In recent years, record low numbers have been achieved and continue to be at or near target levels for sea lamprey abundance. The St. Marys River continues to be one of the largest producers of sea lampreys to Lake Huron and additional actions have been taken to address this challenge. Controlling larval abundance in the St. Marys River along with increasing lampricide treatments throughout the basin and focusing on the largest sea lamprey producing streams have contributed to the decline in sea lamprey abundance. Lake trout (Salvelinus namaycush) restoration efforts along with increased sea lamprey control has facilitated natural reproduction and increase in wild stocks across the basin. The fish community objective for sea lampreys in Lake Huron has not been entirely met and efforts to achieve this objective are ongoing.

从 1960 年对休伦湖溪流进行第一次杀灭灯剂处理开始，在休伦湖支流中使用杀灭灯剂和维持迁移障碍仍然是控制海七鳃鳗（Petromyzon marinus）的主要方法。）。在新千年之前的几年里，休伦湖的海七鳃鳗丰度保持在高水平，但远低于控制前估计的 700,000 只成年海七鳃鳗。二十年后，开发并采用了多种海七鳃鳗控制策略，以进一步减少休伦湖中海七鳃鳗的数量。近年来，已达到创纪录的低数量，并继续处于或接近海七鳃鳗丰度的目标水平。圣玛丽斯河仍然是休伦湖海七鳃鳗的最大产地之一，并已采取其他行动来应对这一挑战。控制圣玛丽斯河中的幼体丰度以及在整个流域增加杀灭灯剂处理并专注于最大的海七鳃鳗生产溪流，导致海七鳃鳗丰度下降。Salvelinus namaycush ) 的恢复工作以及加强对海七鳃鳗的控制促进了整个盆地的自然繁殖和野生种群的增加。休伦湖海七鳃鳗鱼类群落目标尚未完全实现，正在努力实现这一目标。
