But worries remain, because the snakeheads are reproducing rapidly and starting to push outward. The next few weeks will bring a crucial test of the snakeheads' growth, and science's understanding of them, as researchers wait to see if last October's startling mass snakehead migration is repeated.
"It looks like they're becoming pretty solidly entrenched, as far as establishing that beachhead here in the Potomac," said Steve Minkkinen of the U.S. Fish and Wildlife Service.
Over the past year, the snakeheads have spread out and become endemic in about 15 miles of the Potomac and some of its tributaries south of Washington from a home base of two creeks in Virginia, he said. |
