Sustainable tuna buying guide

Tuna is one of the most popular seafoods and sushi ingredients in the United States. In fact, on average, we each eat two pounds of canned tuna a year! Consumers can find sustainably harvested tuna, but over 35 percent of the most popular kinds of tuna caught globally are considered unsustainable by Seafood Watch standards, so it’s important to know what to buy and what to avoid. 

Quick buying guide

  • Buy canned and pouched tuna from the Atlantic or Pacific when you see one of these terms on the label: pole-caught, pole-&-lines, troll-caught, or FAD-free (also called free school or school-caught).
  • Buy tuna caught in Hawai‘i.
  • Buy albacore and yellowfin tuna caught by U.S. longline fisheries in the Atlantic.
  • Buy skipjack and yellowfin tuna from the Indian Ocean labeled pole-caught, pole-&-lines, or FAD-free, or from the Maldives.
  • Avoid all bluefin tuna, except for the wild-caught Pacific bluefin tuna sources we recommend.*
  • Avoid tuna caught with longlines or purse seines using FADs, except for the sources we recommend.*
  • Avoid tuna caught in the Indian Ocean, except for the sources of skipjack and yellowfin tuna we recommend.*

* Scroll down to see the sources we recommend.

Albacore caught with trolls or pole-&-lines is on our Super Green list—good for you and the planet!

What to buy or avoid?

It’s pretty easy to find sustainable canned or pouched albacore (white tuna), skipjack (chunk light or light tuna), and yellowfin (ahi). If the tuna is fresh or frozen, find out the species, where it was caught, and how it was caught, then check our recommendations below.

Canned tuna

  • Buy canned and pouched tuna from the Atlantic or Pacific when you see one of these terms on the label: pole-caught, pole-&-lines, troll-caught, or FAD-free (also called free school or school-caught).
  • Buy skipjack and yellowfin tuna from the Indian Ocean labeled pole-caught, pole-&-lines, or FAD-free, or from the Maldives.
  • Some brands, such as American Tuna and Wild Planet, provide information about how the tuna was caught, but always check the label. The Monterey Bay Aquarium Seafood Watch program doesn’t formally endorse specific brands, and other ocean-friendly canned/pouched tuna products may be available at your grocery store.
  • Whole Foods Market and MOM's Organic Market have sustainable seafood policies that cover their canned/pouched tuna.
  • Take a pass if you don’t see one of the above terms on the canned/pouched tuna label. Note: Dolphin-safe does not mean the tuna is environmentally sustainable, and “line-caught” usually means the tuna was caught with longlines.

Albacore

Albacore populations are healthy in the Atlantic, Indian, and Pacific Oceans. It's available fresh, frozen, canned, and in pouches, and is typically labeled “white” tuna.

Atlantic, Pacific, and southern bluefin tuna

Pacific bluefin tuna is no longer considered overfished, and strong management is needed to ensure it’s harvested sustainably. Once heavily overfished, Atlantic bluefin tuna populations have not fully recovered. Southern bluefin tuna are still depleted, but the population is rebuilding and no longer experiencing overfishing.

Bigeye tuna

Bigeye tuna populations are healthy in the Pacific Ocean, but they're experiencing overfishing in the Atlantic and Indian Oceans. Bigeye tuna is more commonly sold fresh or frozen than in shelf-stable forms, and is often labeled “ahi.“

When is tuna environmentally sustainable?

Tuna rated green by Seafood Watch is the most environmentally sustainable because it comes from a healthy stock, and the well-managed fishery has minimal to no impact on other marine life. 

Tuna rated yellow almost always means management of the fishery is considered moderately effective or better, but the fishery has bycatch impacts. In some fisheries, bycatch isn’t a significant problem, but the tuna population is overexploited. 

Wild-caught tuna rated red by Seafood Watch is not environmentally sustainable because it comes from an overexploited stock, is caught in ways that harm other marine life, management of the fishery is considered ineffective, or a combination of these issues. All farmed bluefin tuna is rated red because it’s sourced from overexploited or vulnerable stocks.

What are the main tuna fishing and farming methods?

We define a fishery by the target species and the body of water, such as a defined region of an ocean. Since more than one fishing gear may be used in a fishery, each target species caught by a specific fishing gear will have a unique Seafood Watch rating. 

Fishing methods

About a dozen fishing methods are used to catch tuna, and some are more prone to accidentally capturing other marine life than others. Drifting longlines and purse seines using FADs tend to be the worst bycatch offenders. However, in well-managed fisheries, a variety of measures can greatly reduce the amount of bycatch, even when these methods are used.

Here's a quick look at the main fishing methods used to catch tuna:

  • Drifting longlines have a mainline supported by floats and evenly spaced branch lines with baited hooks. They can be up to 50 miles long and have thousands of baited hooks.
  • Purse seines using FADs surround mahi mahi with a large wall of netting that closes like a drawstring. Floating objects called fish aggregating devices, or FADs, attract mahi mahi and other species, making them easier to catch.
  • Unassociated purse seines also surround tuna with a large wall of netting that's closed like a drawstring purse, but FADs are not used. This fishing method is also described as FAD-free, non-FAD, free school, or school-caught.
  • Trolling lines or handlines and hand-operated pole-&-lines catch tuna with one or more fishing lines with baited hooks. These more selective methods tend to have fewer bycatch impacts. They are also described as troll-caught, pole-caught, or pole-&-line-caught, especially on canned tuna labels.

Farming methods

Bluefin tuna is farmed in marine net pens. Net pens are structures that hold tuna in open water as they grow. Open systems like net pens pose inherent environmental risks, including escapes and pollution impacts.

How to use this guide

Our green, yellow, and red ratings indicate environmental risk. We use our ratings and third-party certifications to make our recommendations. 

Choose

  • Green-rated seafood because environmental risks are low.
  • Yellow-rated seafood because environmental risks are moderate.

Avoid

  • Red-rated seafood because environmental risks are high, often due to overfishing, poor management, or harm to marine life and habitats.

Where to find sustainable seafood

Finding sustainable seafood is easier than you might think. Here’s how to get started.

  • Use Seafood Watch guides. Our Popular Seafood Guide covers the seafoods you’re most likely to encounter and is the easiest place to start. Our national guide covers many more seafoods and works anywhere in the U.S. Our six regional guides are tailored to what you’re likely to find in your part of the country. Our 14 species guides cover all of our recommendations for each species, including salmon, shrimp, tuna, crab, and other popular seafood.
  • Shop at businesses committed to sustainable seafood. Some retailers have made formal commitments to follow Seafood Watch recommendations. MOM's Organic Market and PCC Community Markets follow our recommendations. Whole Foods Market sources green-rated, yellow-rated, and MSC certified wild seafood and has a proprietary standard for farmed seafood.
  • Dine with one of our partners. The Cheesecake Factory and California Fish Grill have commitments to serve sustainable seafood, and Seafood Watch Best Choice Restaurant Program partners offer at least one green-rated seafood dish on their menus. For a meal-kit option, all HelloFresh seafood is green-rated, yellow-rated, or certified.
  • Ask a question. Next time you’re at a seafood counter or restaurant, ask “Do you sell sustainable seafood?” It’s a simple question that does more than you might think. When you ask this question, you’re helping create demand for sustainable seafood and encouraging businesses to offer it.
