There are varieties of beneficial algae such as spirulina, chlorella, diatoms, Scenedesmus, etc. These beneficial algae form a component of periphyton, which not only providesnatural food for fish and shrimp, but is also increasing the culture productivity. These algaepossessed high content of protein source. In addition, these beneficial algae control other um-wantedalgae as well as weed plant in the culture ponds. NUTRIALGAE was produced in such a composite mineral concept to improve the beneficial algal growth in the pond, thus the fish or shrimp receive necessary natural nutrition for growth, colour of the organism and other biological activities.
