Understanding the factors influencing variability in composition of fish assemblages is essential for bolstering resilience coral reef ecosystems, effective management and maintaining sustainable fisheries. The benthic at eight sites poorly studied St. Brandon, also known as a bank fisheries area Indian Ocean, were assessed to discern distribution patterns, including differences between channel (Passe Grand Capitaine, Passe Ile Longue-Canal Coco La Cayane) non-channel (Chaloupe, Anchor Points 1 2, Bain des Dames, Pearl Island) sustainability. exhibited clusters, revealing distinct separation Chaloupe which predominantly featured sand (75.26%) interspersed with sporadic patches characterized by live dead corals rubble. three composed cluster. Coral species across families identified, significant (p < 0.05) observed their cover, particularly cover (LCC). Fish density diversity analyses unveiled 58 from 12 families, no statistically disparity among sites. Total biomass (TFB) target (TB) ranged 138.02 ± 65.04 4110.16 3048.70 kg/ha 28.31 24.52 3851.27 2753.18 kg/ha, respectively. TFB TB differed significantly irrespective sites, Island recording highest biomass. recorded five out surveyed exceeded mean benchmark (B0) Western set 1150.00 560.00 TB, Functional group analysis six discrete groups TFB, scrapers being most dominant. This study presents first report on surveys highlighting case waters Republic Mauritius.
