Crappie are my favorite fish, and I really enjoy catching them. Here are a few tricks that have worked for me:
I like to use really small jigs. 1/32nd of an ounce, or 1/16th of an ounce when I want to get down fast. Tie it on a loop knot, so the jig wiggles more. I like tube jigs the best, though curlytails are good when the fish are more active. My favorite color is smoke with black and gold flakes. Uncle Josh makes this color, and you can pick it up at Sportco and other places where they carry that line. Not GI Joe's, though. My other favorite jig you CAN find there, though. It's the Northlander Gypsi-Jig, black head with silver tail in the 1/32nd of an ounce size. It's a painted leadhead with a flashy mylar marabou type tail. Really knocks them dead. Of course, color depends on the situation, but I've found these to be my old reliables. Both are really effective when tipped with...
Berkley Power Bait Crappie Nibbles. I like the white and green color, but I hear silver flake is good too. Haven't tried that yet. Great for tipping jigs, gives it that extra flavor. Tough to find except in stores that specialize in fishing, though. You won't be picking these up at Wal-Mart, though you can order them from Cabela's. They're generally more expensive than trout Power Bait, too. They run about $4 a bottle. But since we can't use minnows, these are the best.
You can fish vertically, but fishing with a bobber is also really effective when you want to keep at one depth. It's really hard to find bobbers that are small enough, so here's what you do: go and buy some egg shaped corkies, the kind for drift fishing for salmon. You don't need a very big one, just enough so that the small end points down like a bobber. They don't have a high profile, so get some colors that can easily be seen from a distance. I like neon orange. Run the corky up the line, with the small end pointed towards the end of the line. I like to use a bobber stop, but you can also plug the top hole in the corky with a toothpick, and break it off. Instant, very sensative bobber of the right size that won't put you out a buck if you should happen to snag something.
Hope these were useful. There's a very good crappie forum here:
