They are marine macroscopic forms. The two species of red algae namely K. alvarezii and G. edulis was collected from Mandapam coast, Rameswaram. The present study was carried out to investigate the environmental parameters such as pH, nitrate and phosphate and its biochemical parameters namely carbohydrates, proteins and lipids from Gracilaria edulis and Kappaphycus alvarezii. The results revealed under environmental parameters chlorophyll showed the highest peak level compared to carbohydrates, proteins and lipids. In biochemical parameters Carbohydrate, protein and lipid content recorded the maximum peak value of 1.47 at 20th day. Protein and lipid content attains the highest peak value at 10th and 15th day with 1.88 and 1.69 respectively. Copyright@ International Science Community Association
