Just how do scientists study fish in our area lakes and rivers? Naturalists of all ages can join Fisheries Biologists from the Wisconsin DNR to learn about a research method called electro-shocking used to survey fish populations. Be prepared to get wet! Bring your own hip waders, or just wear sturdy old shoes. Meet at the Cable Natural History Museum at 1:00 p.m. and return by 3:00 p.m. Please register online at www.cablemuseum.org by July 25 for this free program.
