What’s in a name? The word ‘HOLDFAST’ refers to the structure that anchors seaweed to its substrate. Incredibly strong, these structures help the seaweed weather even the harshest of environmental conditions. Like nature’s holdfast, we hold tight to our environmental roots and core values. We believe that feeding people nutritious food should not come at a cost to the environment.

Shellfish and seaweed provide the essential macro and micro nutrients, vitamins, fatty acids and minerals necessary for a healthy diet, and growing them actually breaths life back into the ocean. Without the need for freshwater, land, fertilizer or other chemicals, both offer the most sustainable sources of protein on this planet.

We exist to provide resources to strengthen and expand the sustainable aquaculture industry in California and broader United States.
