A jig and pig is one of my favorite baits and I have at least one tied on year round. I have caught fish on them every month of the year, both at night and during the day. But I think October through March here in middle Georgia is the best time to fish them. I never hesitate to fish with a jig and pig any time of year, though.
The jig and pig can be fished in many ways. I usually start by dragging it along the bottom for a foot or so then hoping it up off the bottom an few inches. That imitates a crayfish feeding along the bottom then being startled and trying to get a way. When I hit brush I will pull it up a limb then let it fall back a couple of times before pulling it over the limb and letting it fall. That looks like a bream feeding in the brush. Both are effective for catching bass.
Rocks are one of the best places to fish a jig and pig. I will slide the bait along pulling it over rocks and letting it fall between them. I also hop it and pop it over rocks then let it fall back to the bottom. Spotted bass especially like rocks and a small jig and pig is almost irresistible to them. On riprap or bluff banks, I cast right to the edge and move the jig and pig slowly, keeping in contact with the fast dropping bottom. When it falls I keep my line simislack, watching it for a tick or jump until it hits the next step down, let it sit then move it until it falls again.
Around docks I try to get the jig and pig as far back into shady areas as possible. I work the bottom under the dock probing for cover. On docks with posts I pitch to each one, getting my bait right beside it then letting it fall straight down the post to the bottom. When I go over a cross brace I will pull the bait up and let it fall, just like on brush.
Stroking a jig is not something I do a lot but it is effective. Let your jig and pig fall to the bottom by a post, hesitate a few seconds then stroke your rod tip up a couple of feet, then let it fall back. This looks like a bream that gets spooked by a bass and tries to escape and will often trigger a reaction bite.
I use browns in clear water and black and blue in stained to muddy water, and dip the tails in chartreuse JJs Magic. Bream fins and tails have a chartreuse glimmer in bright light and this helps, and spots just love anything chartreuse.
Give a jig and pig a try. You will catch fish on it.
