A good option instead of bait for all of the panfish (and trout, and even bass) are these nifty little things called Trout Magnets. They're 1/64th oz shad-dart type jigs with 1" split tail grub bodies. Come in a bunch of different colors. A fellow on iFish turned me on to them last summer - and I swear by them now. I started fishing them out at Hagg for panfish, and caught everything from bluegill & yellow perch to trout and largemouth bass. Took them down to Takenitch in September, first cast of the trip nailed a 16" cutthroat, and during the rest of the trip I got bluegill, pumpkinseed, crappie, and largemouth on them.
My favorite color by far is white, fished on a gold jig. Next favorite is translucent tan (not sure what they call the color), followed up with brown, then black. There's a few other colors that I want to try, but haven't yet.
You can find them at Wal Mart locally, or order them online (and they sell them in larger quantity packs than wallys has them) from troutmagnet.com
I fish two of them in tandem, usually by themselves, occasionally under a micro float. Sure beats rebaiting hooks when the fishing is fast paced. We'd often run into schools of perch or sunfish - and there were numerous occasions I got double hookups fishing the tandem rigs. Great lure for kids to fish, and even better that you don't need to worry about packing around worms or grubs or other bait with you. Couple dollars worth of the jigs, a couple $0.25 cent floats, and you're all set.
BTW, I fish these on an ultralight rod with 4lb line - they are pretty tiny after all
