Both of these river fishing techniques will make you a more successful river angler.
The Jig Technique - The jig technique involves the use of small twister tail or marabou jigs. When I say small, I'm talking about jig heads from 3/16 to 1/4 ounce. If you opt for a twister tail (which is probably the most effective of the 2 jig styles) I suggest Berkley's Gulp Grubs. These grub bodies (twister tails) are impregnated with fish attracting scents and are more effective than traditional soft plastics. The goal is to work your jig with the current, bouncing it along the bottom as it flows naturally with the current. The weight of your jig head will need to be adjusted depending on depth and current flow. Most river anglers think of this technique for smallmouth bass and walleye, but the jig technique works very well for almost all species of trout as well.
The Worm Technique - river fishing technique can be used with either live or synthetic worms (such as Berkley Power or Gulp worms). As with the jig technique, the goal is to bounce your offering along the bottom, as it flows naturally with the current of the river. Of these river fishing tips, this is my personal favorite. To rig up for this technique begin by tying a small barrel swivel onto the end of your line. Then tie on a set of gang hooks. Gang hooks are the most effective way to present a worm while fishing. At this point split shot sinkers are added above the barrel swivel for weight. The number and size of split shot will vary depending on water depth and current flow. Again, the goal is to have your worm "roll" along the bottom as it flows with the current of the river.
Both of these river fishing techniques will make you a more successful river angler. The key to both of these river fishing tips is practice. Don't expect to catch a trophy on your first outing, but once the nuances are learned both of these techniques are very effective.
