Officials in Illinois are creating new plans to monitor and control Asian carp in Illinois waterways this year.
The Asian Carp Regional Coordinating Committee outlined a $6.5 million plan on Thursday that includes expanding efforts to remove these fish from the Upper Illinois River below a set of electrical barriers meant to keep them from reaching Lake Michigan.
Biologists are continuing intensive sampling of waterways that connect the lake with the Mississippi River watershed to determine if any carp have breached those barriers, but will cut back on DNA sampling.
The presence of Asian carp DNA will no longer trigger an immediate response. Past responses have included injecting poison into the waterways or “electrofishing,” though no carp were found.
