Tackle & technique

Leopard shark
Leopard sharks cruise shallow mudflats, sloughs and channel edges in bays, most often in less than 15 feet of water, and follow the flooding tide onto the flats to feed on crabs, worms, clams and small fish. Anchor or fish from shore or a pier with a sliding sinker rig and a chunk of squid, mackerel or ghost shrimp on the bottom. The bite is often better into the evening and at night.
Striped bass
Striped bass feed where moving tide pushes bait past structure: inlets, points, jetties, bridge pilings and rips in the surf, usually in 2 to 40 feet of water. Fish dawn, dusk and night hardest, casting plugs, bucktails and soft plastics or drifting live bunker and eels, and chunk bait on the bottom in current. In midsummer the larger fish drop deeper or feed mostly after dark.
Surfperch
Surfperch feed in the troughs and holes within about 30 feet of the waterline, just outside the first set of breakers. Cast a two-hook high-low or Carolina rig with size 4 to 2 hooks and a 1 to 6 ounce pyramid sinker and let the surge work it through the trough. Fish the incoming tide on beaches with a steep drop, and switch to jetties, pilings and bays when the surf is too big.
