When Reuben Goforth, a professor of aquatic ecology at Purdue, first started looking for Asian carp in the Wabash River, it was 2008. He’d see them in isolated pockets of the river, mostly in quiet backwaters. In recent weeks, he’s seen them in the main channels of the river, and lots more of them. “It’s very, very noticeable,” he said. “Their numbers have increased in a period of just a couple years. It’s kind of scary.”
To him, that says the Wabash will eventually become like the Illinois River, infested with bighead and silver carp. He is working on tracking their movements and experimenting with using electricity to disrupt the fish’s eggs and larvae.
