Regenerative ocean farming is a climate-friendly model of aquaculture where seaweeds and/or shellfish are grown in a way that requires no freshwater, feed, or fertilizer.

Seaweed and shellfish can absorb excess nutrients, and help mitigate harmful algal blooms, deoxygenated dead zones, and local ocean acidification. In addition, seaweed has been found to produce 70% more oxygen than land plants and, most importantly from the standpoint of climate change mitigation, absorbs carbon even more effectively than trees.
