Sea lamprey (Petromyzon marinus) are invasive in the Laurentian Great Lakes and parasitically feed on valued fishes. Migration barriers and selective pesticides are used to control sea lamprey, but there is a desire to develop additional control tools such as traps with nonphysical deterrents. Sound has been used as a deterrent for other invasive species, but its potential for manipulating sea lamprey behavior in natural stream conditions remains untested. Here, behavioral responses of upstream-migrating adult sea lamprey in response to low frequency sounds of 70 or 90 Hz was tracked in a small stream (8 m wide) using passive integrated transponder (PIT) telemetry. The low frequency sounds shifted sea lamprey distribution, with up to 30% more sea lamprey detected on PIT antennas without sound compared with PIT antennas with sound playing. Future studies could continue testing low frequency sounds in larger rivers with larger speakers for use as a natural deterrent at sea lamprey barriers to push sea lamprey toward traps.

海七rey鳗（Petromyzon marinus）在小溪流中对声刺激的行为响应

海七rey鱼（Petromyzon marinus）在劳伦大湖中入侵，寄生于珍贵的鱼类。迁移障碍和选择性杀虫剂用于控制海鳗，但是人们希望开发其他控制工具，例如具有非物理威慑作用的诱捕器。声音已被用作其他入侵物种的威慑力量，但在自然流条件下操纵海七lamp鳗行为的潜力尚未得到验证。在这里，使用无源集成应答器（PIT）遥测技术在一条小溪流（8 m宽）中跟踪了上游迁徙成年海鳗对70或90 Hz低频声音的行为响应。低频声音改变了海鳗的分布，与没有声音的PIT天线相比，在无声的PIT天线上检测到的海鳗的数量最多增加了30％。
