On many days, cloudy skies and choppy seas out of Oregon Inlet frustrate summertime cobia fishermen. When conditions make it difficult to find them, it's time to switch gears. The same areas you find cobia - along the beaches from just behind the surf zone to 70 feet of water or deeper and along tide lines and temperature changes - are good places to drop a chum bag and see who comes to visit. In my area the two most common shark species we encounter are the Atlantic sharp-nose and the blacktip. But the same tactics work in other places such as the Gulf of Mexico, where anglers frequent offshore oil rigs in search of tuna, kingfish, jacks and more. Where you fish will dictate what kind of sharks you encounter, but for the most part inshore sharks behave the same. Around Montauk, New York, the waters hold blue sharks and makos. The southeast Florida coast means spinner sharks and blacktips, and from its Panhandle all the way to Louisiana in the Gulf, lemon, bull, blacktip, dusky and sandbar sharks can show up behind shrimp boats or be chummed up near the rigs. But no matter what species appears boat-side, similar tackle and techniques apply. So once you know the basics of shark fishing, you'll be able to target them in different areas.
