That perfectly seared fillet may look like the healthiest choice on the menu, but seafood quality depends on more than appearance. Fish can provide valuable protein and omega-3 fats, yet some choices may come with concerns involving mercury, environmental damage, fishing methods, or farming conditions. Knowing where your seafood comes from can help you make better choices.

Large, long-lived fish are often the ones that deserve the most caution. Species such as bluefin tuna, swordfish, orange roughy, and Chilean sea bass can contain higher levels of mercury. Some may also face sustainability concerns depending on where and how they are caught. As the article notes, “not all seafood is created equal.”

Imported farmed seafood can also vary in its environmental and production standards. Certain shrimp, salmon, tilapia, and catfish may come from farms with different practices involving the environment, animal welfare, or workers. These concerns do not apply to every farm, but they show why the source of seafood matters.

There are plenty of better alternatives for people who want nutritious and more responsible choices. Wild Alaskan salmon, Pacific cod, U.S.-caught wild shrimp, mussels, sardines, anchovies, and responsibly farmed trout are often considered lower-mercury and more sustainable options. Checking seafood guides and trusted sustainability certifications can make choosing easier.

Ultimately, making responsible seafood choices can benefit both your health and the oceans. “While no single meal will change the future of the oceans,” consistently choosing seafood from well-managed fisheries and reputable farms can support healthier marine ecosystems and encourage more sustainable practices over time.
