The Mepps Aglia spinner is the original French spinner. It is the World's #1 Lure. More trophy fish have been caught on the Mepps Aglia than any other lure. The Mepps Aglia is extremely popular world-wide because it will catch just about any freshwater fish and many species of saltwater fish.Lure size is important. The rule of thumb is use smaller lures to catch smaller fish and larger lures to catch larger fish. Keep in mind plain spinners present a smaller profile than dressed spinners, so they will appear smaller to the fish. This makes them perfect for panfish and small stream trout. Fishing with dressed spinners can produce larger fish, but, when stream trout fishing, you will probably catch more fish using plain spinners. Mepps plain treble or single hook Aglias in size #00 or #0 are perfect for panfish (bluegills or sunfish) and small stream trout. They are very light, however, and require a nimble rod, equipped with a light action reel spooled with light line; nothing heavier than six-pound-test. Two-pound-test to four-pound-test is better. Aglias in size #1 and #2 are perfect for larger stream trout and large bluegills, sunfish and crappies. Size #2 Aglias are also excellent for smallmouth bass and walleye. These sizes are ideal for teaching youngsters the basics of spinner fishing, as they are heavy enough to cast well with light tackle, yet they are small enough to catch a wide variety of fish.
