Sure. There were two things that happened. One was the creation of a bunch of spawning habitats, primarily for steelhead in the area, which turned out to be wonderful sea lamprey spawning habitat. The second thing was an overall improvement in the water quality that occurred in the St. Mary's River. The water quality prior to the late eighties had been a real impediment to sea lamprey effectively spawning in that area.
What the commission was able to do was to develop a deep water electrofisher. We could drop this thing down into the water column, shoot electrical current into the sediment, the larval lampreys would then swim up, and like a huge vacuum we would suck them up into vessels on the surface.
