The present study is to known the water quality parameters and growth of seaweed Kappaphycus alvarezii in nine different coastal area of Gujarat coast. The growth measured in kilogram. Growth is a dynamic parameter and requires the increase in a certain quantity per unit time and maximum was recorded in summer, winter and monsoon season 22.4 kg, 16.7 kg and 11.9 kg in Okha mandal and the minimum growth was recorded 3.6 kg, 2.5 kg and 2.6 kg in Ghogha. Medium growth was recorded at Diu in all seasons (20.6 kg, 15.5 kg and 9.6 kg). Correlation coefficient of showed a significant positive correlation observed between total phosphate and nitrate (P< 0.10 = 0.877) and positive significant coefficient observed between seaweed growth and total phosphate(P< 0.05 = 0.750). The results of water nutrients nitrate and total phosphorus was high in okha mandal area (summer 19.2 μg l -1 and 2.2μg l -1, winter 17.4μg l - 1 and 1.9μg l -1, monsoon 15.4μg l -1 and 1.3μg l -1) and lowest was recorded in Miyani village. This study indicates that out of nine stations Okha Mandal and Diu coastal area suitable for Kappaphycus alvarezii culture in summer, winter and monsoon seasons.
