We're turning the tide.


At BettaF!sh, our priority is conserving the oceans. We are achieving that by building a whole new industry of impact-enhanced foods based on seaweed. Our TU-NAH tastes and looks just like tuna, but is 100% plant-based. Seaweed cultivation itself is regenerative and a sustainable alternative to fishing. This means you can continue to enjoy your favorite "seafood" guilt-free.


We’re team ocean.

We’re bringing the super ingredient seaweed to the forefront. Bursting with great taste, nutritional value and environmental impact, it’s the hero of our TU-NAH and offers coastal communities new, more sustainable income opportunities.
Time to taste the ocean!
