Mad River Fish Pills are small, foam balls commonly attached to steelhead and salmon baits to help keep them buoyant. Mad River's attractant Fish Pills work in unison with your favorite bait or yarn, in spawn sacks (not included) or in egg patterns when fishing salmon, steelhead, trout and many other game fish. Composed of soft foam, they help float your hook and bait, whether you're fishing rivers, streams or lakes. Use them to prevent hooks from snagging the bottom and to position hooks and bait in fish's strike zones. We offer the Mad River Fish Pills in two sizes: #1(7-8mm diameter) and #2(9-10mm diameter) in several excellent colors. 100 per pack.
