What to Know About Various Tuna Species

Did you know that in the U.S., we consume approximately 1 billion pounds of canned and pouched tuna annually, with only coffee and sugar being more popular in terms of items sold per shelf space in groceries? Did you also know that our ocean provides various tuna species, and that we usually only see a couple on retail shelves?

With such high U.S. tuna consumption, the likelihood is that you have tried some yourself. However, how much do you know about tuna? In this article, we’ll share a bit more about the different species of tuna, where they live in our oceans as well as why it’s imperative that we pursue sustainable fishing methods. You’ll also find some of our new favorite tuna recipes.

How many species of tuna are there?

There are fifteen species of tuna. However, the species that are most commonly found on grocery shelves are albacore (known as white tuna) and skipjack (often known as light tuna). Yellowfin and bigeye are also found on shelf, though not as frequently as albacore and skipjack. Below are highlights of eight species – those found on grocery shelves as well as bluefin and frigate tuna.

    Where do tuna live?

    Tuna are found throughout our oceans. Below are where the eight species we’re discussing make their homes:

    Albacore tuna

    Albacore tuna are found in the North Pacific Ocean, South Pacific Ocean, North Atlantic Ocean, South Atlantic Ocean, Mediterranean Sea and Indian Ocean. They are also referred to as “white tuna.” Albacore accounted for only around 4% of the tuna caught in 2021.

    Skipjack tuna

    Skipjack are the smallest of the commercial tuna species and the most popular for consumption. They are found mainly in the Atlantic, Indian, and Pacific Oceans. Skipjack accounted for about 56% of the tuna caught in 2021.

    Yellowfin tuna

    Yellowfin tuna accounted for around 31% of the tuna caught in 2021. They can be found in the tropical and subtropical areas of the Atlantic, Indian, and Pacific Oceans. 

    Bigeye tuna

    Bigeye are found in the tropical and subtropical areas of the Atlantic, Indian, and Pacific Oceans at lower depths than skipjack and yellowfin tuna. This results in them having more fat in order to better insulate their bodies. Bigeye accounted for about 8% of the tuna caught in 2021.

    Bluefin tuna

    There are three types of bluefin: Atlantic, Pacific, and Southern. 
    1. Atlantic Bluefin are the largest of the bluefin tuna species. It can be found in subtropical and temperate waters of the Atlantic Ocean and the Mediterranean and occasionally in the Black Seas.
    2. Pacific Bluefin is slightly smaller than Atlantic Bluefin but still large. It can be found from the Gulf of Alaska to Baja California in the East and from Sakhalin Island to New Zealand in the West.
    3. Southern Bluefin also reach large sizes like the other bluefin. They can be found in the Southern Hemisphere of the Atlantic, Indian and Pacific oceans.

    Frigate tuna

    Frigate tuna are similar to frigate mackerel, bullet mackerel and bullet tuna. Frigate are an important food source for larger tuna species, billfishes, barracudas, sharks and other predators. Adults can be found in coastal or near-coastal waters, while juveniles are widespread throughout the world's oceans.

    What fishing method is used to catch tuna?

    There are multiple fishing methods used to catch tuna, however, not all of them are equal. At Wild Planet, we selectively harvest our tuna using 100% sustainable pole & line, troll, or handline caught fishing methods – nets are never used. By fishing in this way, we virtually eliminate bycatch – species unintentionally caught in the process of fishing a targeted catch. Sustainable fishing gives tuna, and all sea life, a chance to repopulate naturally. This keeps our wild oceans diverse and healthy.

    Below are a few sustainable methods used by Wild Planet along with several wasteful methods which we never use, but ones which you may hear discussed by fishing and sustainability organizations around the world.

    Sustainable methods

    • Pole & Line / Handline: Practiced for centuries, pole & line fishing catches tuna from a bait boat. Live sardines and anchovies are thrown overboard attracting schools of tuna creating a feeding frenzy. Using a pole & line, fishermen catch and haul younger, migratory tuna onto the boat one-by-one.
    • Trolling: This sustainable fishing method involves towing artificial lures (also known as jigs) behind a slow-moving boat. When fishing for tuna, vessels rig their boats with approximately 10 to 20 fishing lines. Each is attached with a barbless jig that appeals to the targeted species.

    Wasteful methods

    • Purse Seines with the use of FADs: FADs (Fish Aggregating Devices) are radio-beaconed floating devices that attract all types of fish beyond a targeted species. Small fish and tiny tuna aggregate to the cover of the FAD. These smaller fish then attract larger fish, which lures in even more species like sharks and turtles. These are caught along with the tuna and many are discarded. Catching tiny juvenile tuna results in lost food supply, while bycatch mortality disrupts the ocean’s natural balance and threatens local communities’ food security.
    • Long-Line Fishing: The most common method used to catch albacore worldwide, long-line fishing uses long lines that attract a variety of ocean species beyond tuna. Endangered sea turtles, sharks and other fish also bite the bait creating wasteful bycatch mortality and an unbalanced ocean ecosystem.

    What type of tuna is best?

    The U.S. Food and Drug Administration recommends making fish a regular part of your diet. All tuna have incredible health benefits. This includes protein, vitamin D, vitamin B12, calcium, and EPA and DHA omega-3 fatty acids. 

    • Protein: Necessary to build strong and healthy bones, muscles, cartilage, and skin.
    • Vitamin D: This vitamin is critical for ensuring bone health and supports the immune system.
    • Vitamin B12: This vitamin is essential for red blood cells, nerve function, and the production of DNA.
    • Calcium: This mineral plays an important role in building and maintaining strong bones, as well as a healthy heart, muscles, and nerves.
    • EPA and DHA omega-3s: These fatty acids reduce inflammation and improve overall blood flow.

    How can tuna be prepared?

    You will frequently find tuna sold as tinned fish in grocery stores. Research shows that one in four American consumers serve tuna once or more a week. While tinned fish can usually be eaten as-is, here are some of our tried and true tuna recipes for albacore and skipjack, two of the 100% sustainably caught species which Wild Planet offers.
