Not trying to be smart ass here, just provide some info. That fish is a confusing one for a lot of people and comes up often misidentified. That’s one thing I have learned from fishing all over the world is there is a lot of common names and fish that look similar. King Mackerel (Scomberomorus cavalla) like the one in the pic below ranges in the western Atlantic.
Your fish is most likely a Narrow-barred Spanish Mackerel. (
Scomberomorus commerson) His range is included in your area. They are considered a better food fish than the kings and trophy fish for most indo-pacific spearfisherman. Here is a pic of a Narrow-barred Spanish Makerel.
Great catch and thanks for the cool report. Good reminder to always hang in there! Its not how you start the day, its how you finish!
