That is a red drum or puppy drum, the North Caroline state fish. I hope you threw that one and the others back into the water. In North Carolina, there is a slot limit for them, meaning any fish less than 18" and any fish over 27" must be released. You can only keep 1 fish per day that is between 18 - 27". Out at Cape Hatteras they catch them in the 30 - 40 lb range during the Fall run.
By the way, what kind of bait did you catch them on?
