Looking good in those waders. Fish Biologists Shawn Nowicki, Cheryl Kaye and Mary Henson check sea lamprey traps in the Grand River, Ohio.

We are a science based agency. Determining pH levels in treatment streams allow crews to use the right amount of lampricide to target sea lampreys while minimizing non-target impacts.
