Synthetic Hormones Show Promise in Controlling Great Lakes Lampreys

If the builders of the Erie Canal, which linked the Great Lakes to New York, could have imagined the devastation to native fish species that the sea lamprey would cause, they might still be hauling goods with draft animals. A long battle has a potential new solution in the form of synthetic hormones that might be used to misdirect lampreys. “‘We see it as away of tricking these spawning lampreys, and then you can do things to manipulate their behaviour in ways that would work against them — for example you could lure them into streams without suitable spawning habitat, or just into traps.'” Richard Black for the BBC News.
