Tunas and most bonitos feed more often on pelagic, schooling fishes, but no tuna or bonito feeds exclusively on any one type of prey. The dogtooth will readily consume a smaller mackerel, squid or other pelagic fish.When hooked the first run of a dogtooth tuna is fast and long and is followed by a deep, circling, and tough fight. It is usually taken incidentally while deep trolling or deep live or dead bait fishing for other species in the vicinity of an offshore reef, though some are caught on rigs trolled on or near the surface. Anglers who specifically target dogtooth tunas will typically target them using heavy vertical jigs. This fish has been known to take mackerel, mullet, squid, strip baits, spoons, plugs, feathers, and plastic lures. The following are fishing methods used to catch this fish:
The dogtooth tuna is noted for its lack of scales (except on the corselet and along either side of the lateral line) and for its large conical teeth; features which have given this fish its namesake. It is actually a member of the bonito family. The first dorsal fin has 13-15 spines; the second is higher and has 12-14 rays followed by 6-7 dorsal finlets. The anal fin has 12-13 rays and there are 11-14 gill rakers on the first arch. The lateral line is prominent and wavy, ending in a keel on the caudal peduncle. It is the only bonito that has a swim bladder and a large, single interpelvic process. There are no dark stripes or spots on the body. The second dorsal and anal fins are tipped with white.
