I do not know the man in this picture, nor do I know anyone who has caught a fish this large. I have, however, seen many pictures like the one above (most often hanging on a wall in movies, next to a stuffed swordfish).
In case you are wondering, the fish in the picture above is a Greater Amberjack fish.
Here is more about the species:
Family Carangidae, JACKS and POMPANOS
Seriola dumerili
Description: dark stripe (variably present) extends from nose to in front of dorsal fin and “lights up” when fish is in feeding mode; no scutes; soft dorsal base less than twice the length of the anal fin base.
Similar Fish: other Seriola.
Where found: OFFSHORE species associated with rocky reefs, debris, and wrecks, typically in 60 – 240 feet of water; sometimes caught NEARSHORE in south Florida; juveniles associated with floating objects and may occur in water less than 30 feet deep.
Size: common to 40 pounds.
*Florida Record: 142 lbs.
Remarks: largest of the jacks; thought to spawn OFFSHORE throughout most of the year; feeds on squid, fish, and crustaceans.
