Stew .... that "might" work, if the fish are kinda hungry. But it's usually better for a jig to be moving.
You might also consider simply casting the jig out and VERY slowly reeling it back in, when you're fishing at night. As long as you can see your line, from rod tip out into the darkness, you'll know when you get a hit. It's usually just one quick bounce of the line ... and when that happens, set the hook !! It can also be sudden slack line, like your jig has hit bottom, but you know it can't have. Set the hook !! And, of course, any hit that you "feel" ... you set the hook.
There are members that put a jig on the end of their line, then tie a loop up the line about 12-18" and put a hook on the loop (& a minnow on the hook) ... and fish it straight down from the rod tip, or even under a bobber ... and they say they catch Crappie on the jig. I've just never tried it that way, so I can't attest to having any experience with those setups.
You're probably going to have minnows with you, anyway .... so, if your jig under a stationary bobber rig doesn't get you any hits, then tip the jig with a minnow. Just run the hook point from under the V folds of the underside of the minnow's mouth, and out between the nostrils, and the minnow will be lively and live for quite some time.
But, if you're thinking about using jigs & NOT taking minnows ... you're likely going to have to keep the jig in motion
