Very easy with a sharp filet knife. Watch how it's done on U-Tube video. The hardest part is catching the flounder in MD. waters. It was pretty easy for me in FL. beach fishing.Those are pretty fillets from that flounder....that is truly a skill that I have not come close to mastering.
I was casting were the fish hang out. Wild beaches were people don't swim. The fish are not far out from the beach. They like to stop in areas like this, and they will be along the beach no more then 15' from shore. A lot of times right at the beach. If you go beach fishing in FL. this is what to look for. If you find places like this on the beaches, you will catch fish. Stay away from the swimming beaches. Good Luck!Were you "fan casting" ?
