Do not run scared when you hook a large fish. Don't reel in the fish while it is swimming away. Hang back and let your rod's drag do the work the work for you. As soon as you have the hook firmly connected to the fish, start reeling. Hold your fishing pole at a 45-degree angle and point it toward the fish.
Look at the water's current to locate the deep-water areas. Look into locations that have the deepest water when you are river fishing. Fish normally congregate in these types of locations. They might also be found near substantial rocks or ledge developments. Keep in mind any great fishing spots you discover so that you can fish there again in the future.
