Distribution and Diversity of Six Common Reef Fish Families along the Egyptian Coast of the Red Sea
Magdy A. Alwany and Michael Stachowitsch

Abstract:
This study examines the distribution and diversity of six common families of reef fishes (Pomacentridae, Chaetodontidae, Pomacanthidae, Acanthuridae, Labridae and Scaridae) in two reef zones at 20 sites along the Egyptian coast of the Red Sea. A total of 91 fish species were recorded, representing 41 genera. The Sharm El-Sheikh region has the highest number of species (75), whereas the northern part of the Gulf of Aqaba has the lowest number (40). The highest average abundance was recorded at Ras Mohammed (2921 fish/600 m3). Most individuals belonged to the families Pomacentridae (52.1%), followed by the Acanthuridae (19.5%), Labridae (14.7%), Chaetodontidae (7.1%), Scaridae (5.2%) and Pomacanthidae (1.3%). Average species richness ranged from 6.2 (northern Gulf of Aqaba) to 10.2 (Sharm El-Sheikh). In general, the number of species of all selected families was higher on the reef slope than on the reef flat. There was no clear zonation (restriction to reef flat versus reef slope) in the distribution of Pomacentridae, Acanthuridae, Labridae and Scaridae along the Egyptian reefs, although preferences were evident. On the other hand, certain species of Chaetodontidae and Pomacanthidae clearly preferred the reef slope. This study reveals clear geographical differences in the fish communities of the Egyptian Red Sea reefs, differences that should be taken into consideration for crucial future conservation efforts here.
