Fisherman captures invasive silver carp in St. Croix River

NEAR HASTINGS, Minn. (KTTC) –  A commercial fisherman recently found an invasive silver carp while netting along the St. Croix River near Hastings.

He contacted the Department of Natural Resources, per regulations, to inform them his crew would be netting in that area. When he came across the silver carp, he immediately notified the department.

“Captures of individual invasive carp are disappointing but not surprising,” said invasive fish coordinator, Nick Frohnauer. “This silver carp was captured in an area that is heavily fished in the spring, as it is an overwintering area for several species of fish.”

The invasive silver carp has a large impact on Minnesota’s environment, as they compete with native species and pose a threat to lakes and rivers.

This is the first time since 2017 that someone found a silver carp.

“They are not from Minnesota, and they can cause problems here: interfere with other fishes food and resources. Silver carp can also jump out of the water and cause problems with that… like the boat motor. They can jump in the air; people can be harmed by them,” said Heidi Wolf, the invasive species unit supervisor for the Department of Natural Resources.

Minnesota DNR staff took the fish back to their office for further processing. “In this instance, there was one invasive carp out of the hundreds of fish handled in the haul,” Frohnauer said.

The department continuously monitors lakes and rivers for invasive species. People who think they may have captured an invasive carp should take a photo and transport the carp to the nearest DNR fisheries office or make arrangements for it to be picked up by a DNR official.
