July 13, 2009 | 12:01 a.m. CDT
Aaron DeLonay, an employee for the Columbia Environmental Research Center, shows David Walchshauser a shovelnose sturgeon on California Island during the Big Canoe River Float on Saturday. Many of the sturgeon in the Missouri River are electronically tagged and monitored because of their status on the endangered species list. Sturgeon were around with the dinosaurs and many found in the river are more than 15 years old.
