The simplest of fishing methods can also be the most effective. Still-fishing is a matter of putting your bait in the water and waiting for a fish to find it. Depending on water depth and what you’re trying to catch, you may want to still-fish near the surface, at a mid-water depth, or right down on the bottom. Using a float, or bobber, makes it easy to fish near the surface, or you can add sinkers to your line to fish deeper. Still fishing is a versatile way to go. You can do it from a pier, a bridge, an anchored boat or from shore. You can still fish on the bottom or off the bottom in ponds, lakes, rivers and streams for a variety of species. And you can still fish during most seasons and during any part of the day. You have to be very patient. You need to wait for the fish to bite. Still fishing is a versatile way to go.

Jig fishing is popular and challenging. Why? Because the person fishing is creating the action that attracts, or doesn’t attract, the particular type of fish he or she is trying to catch. Here’s how it works. Cast out and let your jig hook sink to the bottom. Then use your rod tip to raise the bait about a foot off the bottom. Then let it drop back to the bottom. You can jig up and down, side to side or up and down and sideways. Jig rigs come in all sizes, shapes and colors, and can be used with or without live bait..
