Comparing a skipjack tuna and an albacore tuna

The 6 main differences between a skipjack tuna and an albacore tuna

The main difference between skipjack and albacore tuna is their size, appearance, and culinary usage, especially in the United States. Skipjack are smaller, considered lower quality, and are caught in much higher numbers than albacore tuna.

Tuna is an interesting food as it can make up some of the most high-priced cuisines in the world or it can come in a can on a grocery store shelf. This variance is primarily due to the rarity and marketing of the species of tuna being caught. Most of the world’s tuna supply comes from skipjack tuna, with 70% of the US canned tuna market being entirely composed of skipjack. Albacore is generally marketed as a higher quality canned option than skipjack.

Both of these fish are top predators that live in tropical and temperate waters worldwide. Additionally, they often migrate together, with large tuna migrations consisting of multiple species of tuna. Skipjack and albacore are often seen swimming with one another, as well as larger, more prized tuna, like yellowfin and bluefin.

Despite their similarities, there are some clear differences between the two fish. Let’s take a look at the skipjack and albacore tuna to find out what makes them unique!

The albacore tuna also has a few names that it goes by, albeit a few less than the skipjack. Its scientific name is Thunnus alalunga, but other names include the white tuna and the longfin tuna.

Skipjack Tuna vs Albacore Tuna: Distribution

Both species of tuna are recognized around the world. Despite this worldwide distribution, there are a few differences in the scale that they are found in certain regions. The skipjack tuna can be found in tropical and temperate waters worldwide. They often migrate and swim in groups, usually with other tuna species, including the albacore.

The albacore tuna also has a worldwide distribution. Like the skipjack, the albacore prefers tropical and temperate waters in the uppermost region of the ocean. There are six distinct stocks that are fished across the world, however. These six stocks have a particular distribution that they stick to and can be found in the Atlantic, Pacific, and Indian Oceans, plus the Mediterranean Sea.
