The Globe and Mail is reporting that biologists have developed a synthetic pheromone that attracts female sea lampreys (Petromyzon marinus) away from males and into traps. The chemical will soon be put to the test in lamprey-infested streams in both Michigan and Canada, and is expected to join lampricides, trapping, and underwater barriers as another tool in the arsenal of those trying to rid the Great Lakes of this invasive species.
For those who want to dig deeper into this research, you can check out the original article in the Proceedings of the National Academy of Sciences (subscription required at the time of this post). Bonus points to the G&M for using the fish's scientific name.
