Can seaweed save the planet?

Updated: Nov 8

Flo Taylor - Co-Founder High Tide Seaweed: "I watched 'Seaspiracy' a while ago, and it was a brilliant shocking documentary, that got the message 'Stop eating fish' across with a punch. And I agree, we do all need to eat a lot less seafood, and industrial fishing needs to stop completely. However, the documentary only lightly touched on the fact that people in coastal communities across the world still need to eat, and only briefly discussed algal based foods and shellfish aquaculture."


Here at High Tide Seaweed, we're less doom and gloom, and instead want to share positive solutions to the ocean crisis. This is where restorative ocean farming comes in. We are linked with Câr-Y-Môr - Wales's first restorative ocean farm growing shellfish and seaweed. This type of ocean farming does not involve any salmon or lice, and is incredibly simple. You have horizontal ropes strung between buoys - the seaweed grows vertically downwards off the ropes, mussel lines hang off the ropes and cages are attached for oysters. The seaweed and shellfish absorb carbon and excess nutrients in the water column as they grow, require no fertiliser or water input, and once harvested, provide a super nutritious, local food source for the community.

The underwater farm also creates a habitat for many marine species, thus also improving local marine ecology. Meg Haines (previous employee at the farm) described it as

“like creating underwater gardens. We have the potential to heal entire ecosystems, whilst providing people with local, nutritious and sustainable food"

Alongside ocean ecosystem protection and restoration, we believe that sustainable well-designed aquaculture systems are the way forwards.
