Rongbient doubles local shrimp farmers' income with integrated seaweed technologies in a seaweed cultivation system that uses tissue culture technology coated on a low-cost cultivation system that it rents out to extensive shrimp farmers. The system helps purify water and add natural food sources for shrimp, improving shrimp production and adding a layer of income on seaweed harvests that's 100% equivalent to their current income on shrimp. Rongbient buys back dried seaweed from these farmer and processes it into a supplement feed for intensive shrimp farmers to replace 5% of their current feed and improve shrimp immunity against diseases like vibrio parahaemolyticus and whitespot.
