Spirulina with a protein-basedjelly concept that provided the whole amount nutrient factor to the fish or shrimp. GREEN-PROTEIN has been produced in such a jelly concept, so that the nature of the spirulina can be retained as whole and when the aquatic organism consumed the GREEN-PROTEIN, it leads to high production and low feed conversion ratio. GREEN-PROETIN consumption by the shrimp or fish is well appreciated to encourage the eco-friendly aquaculture.
