Found worldwide in tropical and warm temperate seas, the dolphinfish is pelagic, schooling, and migratory. Though occasionally caught from an ocean pier, it is basically a deep water species, inhabiting the surface of the open ocean. Dolphins are extremely fast swimmers and feed extensively on flying fish and squid as well as on other small fish. They have a particular affinity for swimming beneath buoys, seaweed, logs, and floating objects of any kind. Successfull fishing methods include trolling surface baits or artificial lures; also live bait fishing or casting. If the first dolphin caught is kept in the water, it will usually hold to the school, and often others will come near enough to be caught by casting.
