Ya, I have fished Kelly point for sturgeon.
Quite a while back. Back then we used whole smelt, Usually took an 8 oz weight, with a fairly long cast. 30,lb test mainline min. with 50-80 leader. Strong hooks with stout swivels, knots must be good. A big sturgeon will break lesser gear.
If you get lucky and hook on to a big one, your in for an arm tiering struggle. Gear up heavy, but a sensitive tipped rod is helpful. Even the biggies bites can be very light. Careful not to set the hook early, you will just jerk it away from them them. Wait till they are on.
Wasn't hard catch them, was hard to get a keeper sized one. Not sure sturgeon are legal to keep, be sure to check the F&G laws. Be gentile with them on release, they are not as tough as some people believe.
good luck.
