Mark Adams of Pocatello caught a record breaking trout in the American Falls Reservoir on Monday, July 25. Idaho Fish and Game completed genetic and age analysis on the fish. The record fish is a rainbow-cutthroat trout hybrid - a female cutthroat trout mated with a male rainbow trout. The 6-year-old fish weighed 34.75 pounds, and measured 41 1/8 inches long with a girth of 27 1/8 inches. It was caught on a 10-pound test line with a jig.
