Implications that more study is needed are exasperating the science community, Taylor said. Science has done its job by reaching thoughtful and clear conclusion. Now, he said, is a time for action or at the least a clear decision not to take action.

"I am tired of studying what we already know is going to happen," Taylor said. "We've watched this coming on for 10 years. We know what's going to happen."

Taylor said science clearly points to the likelihood that invasive Asian carp, which are voracious feeders, will prove to be highly effective food competitors to native fish species. It's not the vast open areas of the Great Lakes he sees as threatened, but rather the lakes near shore areas, wetlands and tributaries rivers that now serve as rich habitat for diverse and highly productive fish communities, including our economically important game fish.

"The Asian carp are going to whack the tributaries," Taylor said. "They're going to eat all the food they eat anything they get in their mouth and that means they'll eat the food base that our resident fish would normally eat. They will change the food web and dominate our streams and near shore regions in the Great Lakes basin."

Congress, according to the paper, can play an important role in addressing the invasive species problem by passing legislation mandating the U.S. Army Corps of Engineers to complete a study that offers a permanent solution based on the best scientific information and engineering technology available.
