The best rig for worm fishing is a simple and effective setup called the Texas rig. This rig consists of a bullet-shaped sinker, a worm hook, and a soft plastic worm. To set up the Texas rig, insert the point of the worm hook into the head of the worm, then slide the worm up the shank of the hook until the point exits the plastic body. Next, push the bullet-shaped sinker onto the line, letting it rest against the worm's head. This rig allows the worm to move naturally through the water, mimicking the motion of a real worm. It also helps prevent the hook from getting snagged on vegetation or debris. The Texas rig is versatile and effective for targeting a variety of species, making it a popular choice among anglers.
