What to know before you keep one
Fluke seasons close in the fall in most states, and minimum sizes differ from one state line to the next, sometimes by a half inch.
State water or federal water
Maine rules apply in state waters, generally out to 3 nautical miles. Summer flounder are jointly managed by ASMFC and the Mid-Atlantic Fishery Management Council. Federal recreational measures for federal waters are set by NOAA Fisheries and can differ from state rules. NOAA Fisheries · summer flounder ↗
