Abstract

This study aimed to estimate the distribution and feeding ecology of the angelfishes (Family Pomacanthidae) in Shalateen region, Red Sea, Egypt. The total number of recovered species was six species, where Centropyge
multispinis and Pygoplites diacanthus were the most abundant at most sites, while Pomacanthus imperator and P. maculosus were the lowest. The royal angelfish, Pygoplites diacanthus, was represented in all sites and all reef zones
in Shalateen region. Most angelfish species were not found on the reef flat (except Pygoplites diacanthus), since they prefer the reef slope and increase with depth. Based on the number of individuals, the reef flat comprised only 2.7 % of
the total Pomacanthids population, while the slope comprised 97.3 % of population (34.1 % at 1-10 m depth and 63.2 % at 10-20 m depth). The highest feeding rate was recorded for C. multispinis, with 84.3±26.4 bites⋅(5min)-1, while
the lowest was recorded for P. maculosus, with 58.9±21.6 bites⋅(5min)-1. Most species of angelfishes use biting mode for feeding and diurnal feeders, except Genicanthus caudovittatus that use ram mode for feeding on zooplankton and
nocturnal feeder. Feeding guilds are divided into three categories: a) invertebrate-feeders, represented by three species, namely P. asfur, P. imperator and P. maculosus, b) omnivores, represented by two species, C. multispinis and
Pygoplites diacanthus, c) zooplankton feeder, represented by only G. caudovittatus.
