What Are They?
Mussels are bivalves, a type of aquatic mollusk with a body enclosed within hinged shells.
This nutrient-rich seafood boasts a long, culturally rich history in many parts of the world. For thousands of years, people have harvested them by hand along coastal marine and freshwater waterways. Globally, you'll find bivalve varieties in diverse colors, shapes, and sizes, such as Spain's Mexillón de Galicia and New Zealand's green-lipped mussels-found only in its waters and a staple in the traditional diet of the Indigenous Māori people.
Today, most mussels available for purchase or on menus are likely farmed. Aquaculture-the farming of fish and shellfish-accounts for 94% of global commercial mussel production. Here's the good news: Beyond being healthy and delicious, farmed mussels are rated Green (Best Choice) for their environmental sustainability.
Benefits for You
Mussels are nutritional superstars. A 3-ounce (85g) serving of steamed blue mussels delivers:
- 20g of protein
- 23% of the Daily Value (DV) for thiamine
- 50% of the DV for vitamin B12
- 33% of the DV for iron
- 28% of the DV for zinc
By incorporating mussels into your diet twice weekly-as recommended by the USDA's Dietary Guidelines for Americans-you can enjoy a range of health benefits:
- Support a healthier immune system thanks to nutrients like vitamins A, E, and zinc.
- Reduce cardiovascular disease risk with heart-healthy omega-3s (DHA and EPA).
- Promote brain health, including lowered risks of depression and dementia linked to omega-3 intake.

Benefits for the Planet
Farmed mussels have minimal environmental impact and can even benefit surrounding ecosystems.
Mussels are cultivated using a range of systems:
- Bottom culture involves growing bivalves directly on the seafloor.
- Off-bottom culture suspends them above the seabed. For example, raft culture grows mussels on recycled shells strung on ropes attached to floating rafts.
- Farming typically occurs in shallow coastal waters.
Sustainable, nutritious, and delicious-mussels are a win for your health and the planet!
