The fish is also known by other names such as ahi tuna, Allison tuna, and Pacific yellowfin. Some people also refer to the yellowfin tuna as fin tuna or yellowfinned albacore. In Japan, it is called "maguro" and is highly valued for its rich taste and texture. This species of tuna can be found in the Pacific, Atlantic, and Indian oceans, and is caught using longline, purse seine, and pole-and-line methods. No matter what it's called, yellowfin tuna is a prized catch for commercial and recreational fishing alike.
