Tackle & technique
- Summer flounder
- Summer flounder lie half-buried on sand and shell bottom and ambush bait along channel edges, inlet bars and ocean reefs, from a few feet deep in back bays to about 100 feet offshore. Drift with the tide and bounce a bucktail tipped with a squid or fish strip along the bottom. The bigger fish move to ocean reefs and wrecks in late summer, so follow them out.
- Scup
- Scup school over hard and mixed bottom, rock piles, mussel beds, piers and jetties, usually in 10 to 60 feet of water. Fish a high-low rig with small hooks and squid or clam strips on the bottom, and chum with clam to hold a school under the boat. If nothing bites within 15 minutes, move to the next piece of structure.
- Spot
- Spot school over mud and sand in bays, tidal creeks and channels and around piers and bridges, generally in less than 25 feet of water. Fish a two-hook bottom rig with small hooks and bits of bloodworm or shrimp, and move until you find a school. In fall the biggest fish run out of the sounds past piers and inlets, and the bite can go all day.
