Boca Coast Bait Fish Chum: The difference between the new BC chum and the regular chums (fish food, dog food, cat food) is the performance. This chum sinks like all the others, but then it begins to float. When it reaches the surface it begins to sink again and then suspends at the top of the water column. This is where whitebait (pilchards, greenbacks, herring etc) like to feed. The pinfish tend to stay on the bottom with the remaining chum. This is a good thing because it separates them and also brings the bait in faster. The proprietary blend also has oils that drive the bait crazy. We've tried everything out there and they all sit on the bottom and take too long to work. Our local charter captains report that the new BC chum works several times faster than anything that simply sinks.
