Cutthroat trout get their name from the red-oranges slashes on the underside of the lower jaw. The most common variety available to most anglers is the coastal cutthroat found in many streams and beaver ponds in coastal drainages. Trout that remain in the stream year round may not get any bigger than 8- or 9-inches long but reward the angler with an aggressive bite and enthusiastic fight. The sea-run strain that travels to saltwater to feed may reach an impressive 17 inches.
