Fishbites Fast Acting EZ Shrimp 2Pk can be used on a bare hook or as a trailer on a jig or skirt. You can use them to catch a wide variety of saltwater species. The formula is fast acting and made with fiber-infused gel that disperses the flavor/scent into the water column quickly. There is no cloth mesh in center so once the bait is gone, you’re ready to re-bait instantly without removing any residues. The gel is designed to work in all water temperatures, but it’s best to use in water temperatures below 65F.
