Yes, but I usually use Canadian Tire pool salt from a 40lb sack. It lasts me years and is under $10.00 if you find it on sale. Good for icy sidewalks too. Sometimes I'll squirt some Mrs. Stewarts in a mayo jar of salt then shake it up then pour it in the the bait cooler with the baits. I just leave it in the boat for a 4-5 day trip. They dry out, but will re-hydrate as they twirl if they don't get hit first. No need to refrigerate, but beware of critters at night. Whole bait cooler goes in the freezer if they make it home.
