#### **3.1 Environmental condition**

The mean values of physical parameters were recorded at the study sites. Air temperature ranged between 29 and 29.50°C in the mangroves (interior) and 30°C at the fringes (edges), while water temperature was between 28.50 and 29°C in the interior and 28–29°C at the edges (**Table 1**). On the other hand, the measured pH values ranged between 4.8 and 4.9 in the interior and 5.3–6.1 at the edges, and salinity values were between 1.50 and 1.70 ppm (**Table 1**).
