Hi there! I'm Dr. Ocean, a marine biologist with over 20 years of experience studying marine ecosystems, with a particular focus on sustainable seafood practices. I'm happy to answer your question about which tuna is safe to eat.
## Navigating the Waters of Tuna Safety
The question of "safe tuna" is complex and doesn't have a one-size-fits-all answer. It depends on various factors like:
* Species: Different tuna species accumulate varying levels of mercury, a heavy metal that can be harmful to humans, particularly pregnant women and children.
* Fishing method: Sustainable fishing practices minimize environmental impact and bycatch, contributing to the overall health of the ocean and its inhabitants.
* Individual consumption patterns: Your age, health status, and how frequently you eat tuna influence how much is safe for you.
## Understanding Mercury Levels in Tuna
Mercury is a naturally occurring element, but industrial activities have increased its concentration in the environment. It accumulates in fish, particularly predatory species like tuna, through a process called biomagnification. Higher up the food chain, larger, longer-lived predators tend to have higher mercury levels.
Here's a general guide to mercury levels in different tuna species:
* Lowest Mercury:
* Skipjack tuna ( _Katsuwonus pelamis_ ) is a smaller, faster-growing species with a shorter lifespan, leading to lower mercury accumulation.
* **Tongol or light tuna ( _Euthynnus affinis_ )** is another smaller tuna species with generally lower mercury levels.
* Moderate Mercury:
* Yellowfin tuna ( _Thunnus albacares_ ) sits in the middle ground, with mercury levels typically higher than skipjack but lower than bigeye or bluefin.
* Highest Mercury:
* Bigeye tuna ( _Thunnus obesus_ ) and bluefin tuna ( _Thunnus thynnus_ ) are large, long-lived predators at the top of the food chain, accumulating higher levels of mercury.
## Making Informed Choices for You and the Ocean
Here are some tips for choosing safe and sustainable tuna:
* Read labels carefully: Look for information about the tuna species, fishing method (e.g., pole-and-line, troll-caught), and whether it's certified sustainable by organizations like the Marine Stewardship Council (MSC).
* Choose lower-mercury options: Opt for skipjack or tongol tuna more often, especially for pregnant women, nursing mothers, and young children.
* Vary your seafood choices: Include other low-mercury fish like salmon, sardines, or mackerel in your diet.
* Moderate your consumption: The FDA and EPA provide guidelines on safe tuna consumption levels based on age and health. Consult these guidelines or talk to your doctor to determine what's right for you.
* Support sustainable fishing practices: Look for tuna caught using methods that minimize environmental impact and bycatch, such as pole-and-line or troll fishing.
Remember, enjoying tuna can be part of a healthy diet and support a thriving ocean. By making informed choices and advocating for sustainable practices, we can ensure that future generations can continue to enjoy this valuable resource.

If you eat canned tuna often, choose canned light tuna over canned albacore (white) tuna. Albacore tuna is generally larger, older fish that has accumulated more mercury from its environment. Light canned tuna contains smaller species of tuna such as skipjack, yellowfin and tongol which are lower in mercury.
