First, Why Seaweed?
Many reasons! Seaweed is not only a delicious and versatile dish enriched in essential amino and antioxidants, but it is also good for the ocean and the working waterfront, can feed the world, and is environmentally friendly.
Broken down a little bit further:
- Delicious and Versatile: North Atlantic Kelp, Kombu, Wakame, Sea Lettuce, and Irish Moss species represent a wide range of flavors and culinary uses.
- Happy Oceans: Seaweed creates a habitat for baby lobsters and other marine life. It also sequesters carbon, creates oxygen, and reverses ocean acidification.
- Working Waterfront: At a time when Maine’s traditional waterfront jobs face multiple pressures, lobstermen are turning to aquaculture and kelp farming to diversify their income on the water.
- Health Benefits: Typically, seaweeds have 10x more minerals than land-based plants. Plus vitamins, essential aminos, and antioxidants. Oh, and it’s where fish get their omegas.
- Feed The World: The world needs 50% more food by 2050, with increasing droughts and poor soil. Seaweed is one piece of the global food-security equation.
- Maine = Awesome: Maine is the national leader in seaweed farming and harvest! In 2022 Maine farms harvested over 1,000,000 pounds of kelp from sea farms across the state!
- Shellfish Love: Oyster and mussel growers are adding kelp farms to their operations because beneficial halo effects make their shellfish stronger, healthier, and tastier.
