The Seaweed Solution to climate change.

We’re using sustainable aquaculture to save the ocean.

Since 2020, it has been our mission to grow seaweed to fight climate change and provide a sustainable food source. Seaweed can address two of the biggest challenges of our time – reducing GHG emissions and providing food security for a growing population.

Born from a love of the ocean, Fremantle Seaweed is one of the pioneers of seaweed farming in Australia. Growing Asparagopsis seaweed to make methane reducing cattle feed supplement & a range of edible local seaweed varieties grown in pristine conditions.
