That looks very much like a yellow tail that you catch down south. I go to alabama in the winter to go fishing and we use them for grouper bait. Neat that you caught one here they may follow the trigger fish up with the warm water. They are good eating also.
I can tell you with 100% accuracy that they are banded rudderfish. I went through this same thing last year. I thought they may be small amberjack but the research revealed that they were banded rudderfish. You can't see them in this picture, but in a certain light they will have dull bars down the sides (kind of like a lit up bonito). The white tips on the end of the tail are another dead give away.
I don't know what they are called, but on occasion when things are slow elsewhere, I head out to the range bouy and break out the ultra light. Cast a shad dart up against the red monster, wait a second or two and retrieve (an ultra small piece of squid never hurts). There is an entire school of those suckers using the bouy as structure. Once you hook into one, there seems like there are 30-40 others trying to get in on the action, straying from the confines of the bouy structure. Although I've caught plenty that could have been filleted, I live line them for Mahi-Mahi, Blues and Stripers. Its like feeding candy to a child.
I also strip them. They are one of the best fluke/seabass baits you can possible use. I've returned to the barnegat reef (going to the range bouy after not doing anything on the "Fish Haven") and returning with the strip baits I have oftentimes been the only one apparently catching fish.
It's a Lesser Amberjack! Banded Rudderfish only have bands on the young ones! Fluke love em! Out fished Minnows & Sea Robin belly the other day! They are on all the bouys, in the inlet. Even had them on the no wake bouys in the bay, fun...
My guess is a baby greater amberjack. These are more common in the south and grow up to be a nice fish that fight much like a tuna. Florida, has a limit of 5, hopefully there's some protection for it in the mid-atlantic as it would be a shame to see too many cut up for bait. Here's a pic of an Amberjack we caught this year
The NJ record, caught in 93 was 85lbs! It would be great to see more of these in our waters.
