1. Warmer waters and further south has nothing to do with number of worms.
2. Not enough AJ to supply very many restaurants. THINK ABOUT IT! LOTS will be serving mahi (dolphin) and saying it is AJ. It is still fairly abundant worldwide.. Mahi is to the grilled/blackened dishes like basa and swai are to the AUCE fried whitefish meals.
3. All drum family fish and jacks are subject to worms. Per capita speckled trout have more worms than any other fish.
4. Triggerfish is still king but the bottom of the filet past the rib cage on a sheepshead is as close as anything comes to a substitute for trigger. The top filet is about as good as it gets too.
