The analysis of variance (ANOVA) showed that there was a significant difference between the three mangrove areas (F = 4.27, P < 0.05). Regarding the spatial distribution of juveniles ( Table 2), Hamata mangroves harbored the highest number of fishes where 193 fishes representing 17 species (71.7% of all fishes and 81% of species) were collected. Mangroves of Qula’an and Sharm Al-Bahary have almost the same number of fishes with 37 fishes (3 species) and 39 fishes (5 species), respectively ( Figure 4 and Figure 5). Almost all species occurred in Hamata mangroves. Terapon jarba, Aphanius dispar, Arothron stellatus and Platax orbicularis were absent from mangroves of Hamata.
