The summer flounder is a left eyed flatfish. The eyed side always blends in perfectly with the sea bed. There is usually a scattering of 10 to 14 eye like spots on the body. As in other flatfish, the blind side is white and relatively featureless. The teeth are well developed on both sides of the jaws. The dorsal fin has 85 94 rays; the anal fin has 60 63 rays. There are only 5 or 6 gill rakers on the upper limb of the first arch and 11 21 on the lower limb.
Drift fishing is the most common fishing method and probably the most effective, since drifting covers more bottom and keeps the bait or lure in motion. Many are also taken by chumming while fishing at anchor, by trolling, or by casting from shore or pier. Effective baits include strips cut from shark, fluke menhaden, herring, porgy, young bluefish, or sea robin; or a piece of blue crab. Effective lures include a small spoon, spinner, or feather. Some time must be allowed between the moment the flounder picks up the bait and the strike, or the bail may simply be yanked away. Inshore fishing is best on a running tide, and the largest fish are caught late in the season.
