If you want to make your children happy and encourage their love of fishing, have them fish for species that are generally easy to catch, like bluegill or perch. They are often found near the banks, near the rocks or under a dock. An ultra-light (UL) rod with small, soft lures would be perfect for them.
If you are looking for a bountiful catch of trout, bass, or walleye, choose a medium power spinning (M) rod. For beginners, keep it simple. Two or three spinners, some soft lures and one or two hard lures in a small tackle box is enough to have fun at the water’s edge without breaking the bank.
