Duluth, MN (NNCNOW.com) - The Minnesota DNR says it will begin comprehensive monitoring of bighead, black, grass and silver carp this summer.
Currently, only small numbers of three of those four mentioned, excluding black, are present in the state.
DNR spokespeople say the goal of the monitoring is to better understand the invasive carp's ability to survive and reproduce in Minnesota waters.
Unlike in some states where their numbers are massive, it's difficult to detect them in state waters due to their current low numbers.
But it's the goal of keeping those numbers small that the DNR says adds urgency to the need for monitoring this summer.
