However, the epiphytic algae biomass failed to reflect the nutrient gradient across the transects. It is well recognized
that herbivore activities is an important factor in the control of algae. In addition, several physical factors, such as light, temperature, and salinity, are known to affect the physiology and abundance of macroalgae . At the small scale, the region studied showed no clear variation in its predation pressure, temperature, and salinity.
