Or when you should set the hook?
One of the unique things about fly fishing is that every detail of your cast can be customized to specifically target the sort of fish you're aiming for. You can utilize a general-use fly rod, or you can opt to purchase a rod that has been designed to assist you in specific ways. Combined with the endless amount of techniques and combinations it gives you the most optimal approach at catching large amounts of fish.
Streamer fishing is the closest thing in fly fishing to what most fishermen start out with—lure fishing. Like lures, streamers imitate smaller fish, baitfish, scallops, and other common aquatic life such as leeches or crayfish. Streamer fishing is exciting because you are constantly moving, retrieving your line, and covering lots of water. It is also exciting because when a trout hits your streamer, it feels like a bull is pulling on the other side of the line.
