Phosphorus is one of the most essential minerals for fish growth and bone mineralization which function primarily as structural component of hard tissues Eg. Bone, exoskeleton, scale and teeth. Effects of dietary phosphorus deficiency in fish have been found mainly to be loss of appetite, reduced growth, head and skeletal deformities and under extreme circumstances affect bone formation and lead to death of fish. In semi-intensive culture system the natural food alone usually may satisfy all phosphorous requirements of fish to support slow growth rate and to avoid gross phosphorous deficiency symptoms. Di-Calcium Phosphate (DCP) Super is rich in calcium and phosphorus two vital minerals for fish growth. Calcium and phosphorus are essential for the development of strong bones, teeth and scales in fish. In addition to this, phosphorus is also important for energy metabolism, DNA synthesis and cellular function.
