Monocalcium phosphate is used to provide mineral nutrients such as phosphorus (P) and calcium (Ca) to animals, which are easily digested and absorbed. It is widely used as phosphorus and calcium additive in aquatic animal feed. The water solubility of Monocalcium phosphate in aquatic animal feed is high. Monocalcium phosphate provides calcium and phosphorus to the animals, which helps to improve the body, metabolism, and function of the nervous, immune and reproductive systems, thus increasing productivity. The use of Monocalcium phosphate in feeds promotes the reproductive cycle of animals in addition to preventing abnormal bone development. Monocalcium phosphate has several biological functions and is a key component of energy metabolism. Phosphorus is required for bone growth, formation, maintenance and muscle tissue development. Phosphorus plays a role in maintaining osmotic balance and acid-base buffering
