Catch them in the back bay in OC sometimes. We call them sand perch too
Sand Perch or Silver Perch
Killer King Mackerel bait for pin rigging on the OBX.
I also caught my largest Red Drum 54" on a Sand Perch body section. No other bait around so I chucked it out there. A big front was scheduled to hit Rodanthe Pier at 2:00 AM in the morning, the water was real calm at 1:30 AM and I went to sleep under my rods, every one else had left the pier. At about 2:00 AM the wind started raging and the ocean came alive. My 8600 started wailing and I was bowed up, Drum went under the pier and I had to lever him out.....I had to net it by myself, I had propped the net up on the South end of the Tee and when I managed to get the Drum up and floated over the net, with my rod in one hand and the rope in the other, I just walked backwards, till I had the fish up about five or six feet about the water and then I set my rod down and pulled the big boy over the rail.
