While not widely practiced in the Northeast, fishing live baits in conjunction with chum can be a very effective way to catch bonito. This technique is much more popular in Florida, where it's used to attract Spanish mackerel and little tunny. It works like this: anchor your boat along a channel edge, rip line, inlet or any place bonito have been sighted and there is moderate current. Next, deploy a bag of frozen chum to create an oily slick, then toss out an occasional handful of live baits behind the boat. Once the bonito appear in the chum slick, drift back flies or lures to the feeding fish, trying to match the drift speed of the chum. Every so often, toss out some live baits or small chunks of chum to keep the fish in a feeding mood.
