Table 10 presents the physico- chemical parameters of seawater. It shows that the three sites (muddy, rocky and sandy) slightly differ in water depth during low tide and high tide Sites 1 and 3 slightly vary in current velocity while site 2 got the lowest velocity All other parameters have slight differences on their values on water temperature, transparency salinity and pH. It should be noted that water transparency exceeds the water depth in each site meaning light is able to penetrate the sea bottom which allows the plant for photosynthetic process
