I believe that 1-stop has live mud minnows - they are on the RIGHT just BEFORE you cross the swing bridge. I get my shrimp at Surf City Crab- Cross the bridge and its 3-400 yards on the LEFT - beside Hardee's. 1-stop has shrimp but they always seem to be higher than everywhere else.
Bring a trap. Mud minnow prices are nothing short of criminal and you can find a spot to catch $100.00 worth in an hour if you want to move it a few times. Cast net is good too. Fresh shrimp as per previous post or other fish stores. If you want to PM me I'll tell you where an easy spot to throw a cast net for bait is close by. I also have many salted mullet and I'll be happy to give you a few dozen.
