Here’s the story…from 2002 (after three years, wonder if there’s anything left swimming?)
100-pound catfish invade Susquehanna

LANCASTER — One-hundred pound flathead catfish could eventually take over the Susquehanna River and disrupt its ecosystem, according to the Pennsylvania Fish and Boat Commission.
Last week, commission officials confirmed that the species recently entered the Susquehanna River. And officials are worried the predatory fish, which can reach more than 100 pounds, could cause problems for other species.
The agency is now looking for the help of anglers to help control the growth of the species, which is not native to the river.
“We’re going to start spreading the word that we would like anglers to keep and kill all flathead catfish they catch in the Susquehanna or its tributaries, no matter what the size of the fish,” said Mike Kaufman, a commission biologist.
Kaufman said he verified that the foreign species of catfish was in the river when he saw a photograph of one caught by Lititz resident Greg Misenko.
Misenko said he caught a 15-inch flathead July 13, near the Safe Harbor Dam. He said other men fishing in the area caught similar fish.
In Pennsylvania, flathead catfish are native to the Ohio, Allegheny and Monongahela river watersheds in Western Pennsylvania. The fish are more common in the southern and midwestern portions of the country.
On rare occasions, Kaufman said, anglers catch flathead catfish in the Schuylkill and Delaware rivers, and in Blue Marsh Lake in Berks County.
“We don’t know how they got there, just like we don’t know how they got into the Susquehanna,” Kaufman said.
Flathead catfish look much different than catfish species that are native to the Susquehanna River. Flathead catfish are brown, have a square tail and have a lower jaw that extends past the upper jaw.
Kaufman said the flathead catfish are aggressive breeders. The presence of flathead catfish could significantly reduce the number of other catfish, sunfish, rock bass, smallmouth bass and other species, he said.
Anglers likely won’t be able to kill off the flathead catfish now that they have been introduced, he said. But they can help manage them.
“Just taking one flathead out of the river is going to save a bunch of other fish because a single flathead eats so much — they are truly eating machines,” Kaufman said.
