The company is also contributing to The Ocean Project’s 30x30 campaign, to protect at least 30% of our planet’s land and waters by 2030.

To establish seaweed as a mainstream ingredient in Europe, the BettaFish team have developed the tuna alternative, TU-NAH. It’s a 100% plant-based source of protein, free from soy and wheat. As the world’s favourite and most consumed species of fish, tuna is a market worth over $42 billion, but its popularity is also its downfall – with 43% of worldwide tuna stocks fished at biologically unsustainable levels.

Additionally, tuna fish cannot be bred in the aquacultures, so they are always caught in the wild, often before the animals can reproduce. This not only contributes to overfishing, but bycatch also inflicts irreversible damage on ocean diversity.

Since the start-up launched its TU-NAH Sandwiches in October 2021, a total of 62.2 tons of TU-NAH have been served across Europe, whether in its flagship format, its Spreads, or on menus, restaurants and other foodservice outlets. The 11 tons of seaweed harvested by BettaFish in collaboration with local farms in Norway and Ireland have already absorbed 1.32 tons of CO2. Through seaweed cultivation, the start-up has conserved 1.25 million litres of freshwater.

It's now launching a TU-NAH can, for retail, e-commerce and small restaurants. Anyone interested in getting access before the official launch can sign-up at: https://form.typeform.com/to/UIJkooxu.
