Usually around old ocean pier pilings like the Emerald Island pier you can expect black drum ,flounder, puppy drum and at times pompano and trout. Best fishing is from first light til the sun starts coming on enough for you to feel it. Clear surf is normally best. Fresh shrimp, and live minnows work best around old piers.
Reading the water on the beach is a little tough to explain without pictures but I'll try to give it a shot in case you or someone else don't know how. Most everone who will read this has probably been on a beach at low tide and seen little pools of water that run paralell to the waves with a strip of sand in between the pool and the waves breaking on the beach. Perfect place for the little ones to play away from the waves. Well if you see this it is low tide and at high tide there will be fish feeding there. If you look it over, it is normally open to the ocean on one end and that is the door or break. That temporary pool is called a trough and on the ocean side of the trough it is shallower or dry and that is called a bar. If you wade out into the water, you will notice that just as it starts getting deep it sort of flattens out then it starts getting shallow. That is a sand bar. On the other side of the sand bar it gets even deeper. That is the trough or gut. Again it will have a cut or a door leding to it and that is a place the fish gather.
