Needlefish or hound fish, these prehistoric fish are common around the keys and can be a pain in the a** when fishing for other fish. They are very aggressive and will attack and kill live baits that are too large for them to swallow. The big ones fight pretty good on light tackle, but since they usually are small they are mostly pests. They are easy to catch off the bridges and the Keys with a small hook, and can be used for cut bait, but they don’t have much blood so they aren’t particularly good for bait.
