Ahi fish is a type of tuna that is primarily found in tropical and subtropical waters around the world, including the Pacific, Indian, and Atlantic Oceans. In Hawaii, "ahi" refers to two species of tuna, the yellowfin tuna and the bigeye tuna. Yellowfin tuna has flesh coloration that ranges from pink in small fish to deep red in large fish, and it has a rich, meaty flavor and a firm texture that makes it ideal for a variety of dishes. Ahi tuna is a popular fish for sushi and sashimi, as well as for grilling and searing. The word "ahi" literally means "fire," and dates back to ancient times when these powerful fish would pull the lines out so fast that they would smoke against the canoes of Hawaiian fishers.
