bout 30 more invasive carp were pulled out of the Mississippi River this week, suggesting that the destructive fish may have established a foothold in Minnesota.

The silver and grass carp were caught in shallow backwaters of the river's Pool 8, near La Crosse, Wis., just above the southernmost lock and dam in Minnesota.

More than 50 of the carp were caught in the same pool last spring, and another 14 were caught earlier this year.

Despite the high numbers, however, it's still unknown if enough invasive carp are above the dam to successfully breed or establish permanent populations in the state, said Ben Larson, invasive carp field lead for the Minnesota Department of Natural Resources (DNR).

All the fish caught were adults, he said.

"I don't think it indicates they're spawning," Larson said. "They're mass spawners that need a lot of fish together to successfully pull it off. That's why we came here to do this and why we're so excited about taking 29 of them away."
