Where do their names come from?

Yellowfin and Bigeye tuna are divided into two different types of Ahi tuna species. The name Ahi derives from the Hawaiian word for fire and the smoke created from the fishing line going over the boat so quickly when a ahi is about to be caught. These fish are known as sport fish but are also highly valued in their delicious taste. They are usually caught during the summer months but can be fished all year round. Poke bowls are a well-known dish they are usually known to be made with which is cubed tuna marinated, and served over rice.

What is the difference?

It is easy to tell the difference between a yellowfin tuna and a bigeye tuna by looking at the dorsal, anal and finlet fins. It will be yellow on a yellowfin tuna, hence the name. A yellowfin also has a thinner body in comparison to a bigeye which has a plumper body with a larger head and obvious looking large eyes.

There is also a difference in taste. Bigeye tuna is found to swim in cooler waters and has a higher fat content compared to yellowfin, which gives it a very nice buttery flavour and is great for grilling and won’t dry out as easily. Both tunas are great to use for sashimi and sushi. Yellowfin is know for its milder taste and firmer texture, it is well known for being thinly sliced and used for sashimi.


According to experts Ahi is considered to be a very lean healthy fish. Bigeye and yellowfin tuna are both low in saturated fat and sodium. And the vitamins they are rich in are B6, B12 and phosphorus. If you are looking for a natural source of omega-3 fatty acids and some magnesium, these two are good options as the healthy benefits to your heart.
