Wahoo fish, also known as Ono, is a popular game fish and a staple in many seafood restaurants. Its rich, buttery flavor and firm texture make it a favorite among seafood enthusiasts. However, with the growing concern about mercury levels in fish, many are left wondering: is Wahoo fish high in mercury? In this article, we’ll delve into the world of Wahoo fish, exploring its mercury levels, health benefits, and what you need to know before adding it to your menu.
What is Wahoo Fish?
Wahoo fish (Acanthocybium solandri) is a tropical species found in warm waters around the world, including the Atlantic, Pacific, and Indian Oceans. It’s a fast-swimming, carnivorous fish that feeds on small fish, squid, and crustaceans. Wahoo fish can grow up to 8 feet (2.4 meters) in length and weigh up to 200 pounds (90 kilograms), although the average catch is typically much smaller.
Mercury Levels in Wahoo Fish
Mercury is a toxic substance that can accumulate in fish and shellfish. It’s a concern for human health, particularly for pregnant women, children, and people with compromised immune systems. The mercury levels in Wahoo fish vary depending on factors such as the fish’s size, age, and location.
According to the Food and Drug Administration (FDA), Wahoo fish has a moderate level of mercury. The FDA’s fish advisory list categorizes Wahoo fish as a “good choice,” meaning it has a lower mercury level than some other fish, but still contains some mercury.
Here’s a rough estimate of the mercury levels in Wahoo fish:
| Fish Size | Mercury Level (ppm) |
| — | — |
| Small (less than 10 pounds) | 0.2-0.5 ppm |
| Medium (10-20 pounds) | 0.5-1.0 ppm |
| Large (over 20 pounds) | 1.0-2.0 ppm |
For comparison, the FDA’s safe limit for mercury in fish is 1.0 ppm.
How Does Wahoo Fish Compare to Other Fish?
To put Wahoo fish’s mercury levels into perspective, here’s a comparison with other popular fish:
- Tuna (bluefin): 1.5-3.0 ppm
- Swordfish: 1.0-2.0 ppm
- Shark: 2.0-4.0 ppm
- Salmon: 0.02-0.04 ppm
- Sardines: 0.01-0.02 ppm
As you can see, Wahoo fish has a lower mercury level than some of the more notorious fish, but still contains more mercury than some of the lower-mercury options.

What are the concerns about mercury levels in Wahoo?
Mercury is a toxic substance that can accumulate in the bodies of fish and shellfish. High levels of mercury consumption have been linked to various health problems, including neurological damage, kidney damage, and birth defects. Wahoo, like other large predatory fish, can contain high levels of mercury, which has raised concerns among health experts and consumers.
The concerns about mercury levels in Wahoo are particularly relevant for vulnerable populations, such as pregnant women, children, and people with compromised immune systems. These individuals may be more susceptible to the adverse effects of mercury and should take extra precautions to minimize their exposure.
How does mercury accumulate in Wahoo?
Mercury accumulates in Wahoo through a process called biomagnification. This occurs when smaller fish and organisms absorb mercury from the water and are then consumed by larger fish, such as Wahoo. As a result, the mercury levels in Wahoo can become concentrated, making it a potential health risk for consumers.
The amount of mercury in Wahoo can vary depending on factors such as the fish’s size, age, and location. Generally, larger Wahoo tend to have higher mercury levels than smaller ones. Additionally, Wahoo caught in areas with high levels of mercury pollution may have higher mercury levels than those caught in cleaner waters.
What are the health risks associated with consuming Wahoo with high mercury levels?
Consuming Wahoo with high mercury levels can pose serious health risks, particularly for vulnerable populations. Mercury can damage the nervous system, kidneys, and brain, and has been linked to various health problems, including birth defects, neurological damage, and kidney damage.
The health risks associated with consuming Wahoo with high mercury levels can be minimized by taking precautions, such as limiting consumption, choosing smaller Wahoo, and avoiding Wahoo caught in areas with high levels of mercury pollution. Pregnant women, children, and people with compromised immune systems should be particularly cautious and consult with their healthcare providers for guidance.
How can I minimize my exposure to mercury when consuming Wahoo?
To minimize exposure to mercury when consuming Wahoo, it is essential to take precautions. One way to do this is to limit consumption, particularly for vulnerable populations. Choosing smaller Wahoo, which tend to have lower mercury levels, can also help reduce exposure.
Additionally, consumers can check the origin of the Wahoo and avoid those caught in areas with high levels of mercury pollution.
