Federal regulations are waived for Summer Flounder, and recreational anglers shall follow regulations for the state in which their catch is landed.
Summer flounder may not have heads or tails removed or be otherwise cleaned, cut, filleted or skinned until brought to shore, with the following exception: the white side fillet or white skin only of a legal size fluke may be removed to use as bait. The carcass of the fluke with dark side completely intact must be retained for inspection of size limit and counts against the possession limit.
