Difference Between Ahi and Mahi (With Table)

Fishes are rich in several nutrients. They are a great source for maintaining a healthy diet. Either one wants to lose weight or gain a healthy weight, eating fish can suffice both. However, the nutritional values in fishes vary from species to species. Two of the extremely nutritious and well-marketed fishes are Ahi and Mahi.

Ahi vs Mahi

The main difference between Ahi and Mahi is that Ahi is a species of tuna, whereas Mahi is known as the dolphin fish. Ahi is tastier than that of Mahi, while Mahi has more meat content as compared to Ahi. So Mahi is regarded as fleshier when compared to Ahi. Mahi comes with a rainbow colour range, while in the case of Ahi, the colour becomes deeper as the size increases.

Ahi is a type of tuna fish that comes in two variants- Yellowfin and Bigeye tuna. However, Yellowfin Ahi is slightly heavier as compared to Bigeye Ahi. The size of an Ahi grows from small to very big. The smaller ones are lighter in colour when compared to the larger ones. Although Ahi can go up to 90 kg in weight, it is not as fleshy as the Mahi.

Mahi, on the other hand, is known as dolphin fish as well as ray-finned fish. It grows very fast and reaches full size within a year only. Mahi fishes are found in rainbow colours. They have a flat and square-structured head, which gives them a unique appearance. Their average weight is similar to that of Ahi, but these can go up to 20 kg.
