The study of zoobenthos composition on the Quy Nhon bay was conducted in August 2019. A total of 97 species were recorded, they belong to 77 genera, 57 families, 31 orders, 11 groups and 5 phyla: Mollusca, Arthropoda, Chordata, Echinodermata and Annelida. Among them, Gastropoda was the most diverse group (with 40 species, accounting for 41,24%), the second is Bivalvia (with 27 species, accounting for 27,84%), Crustacea (with 20 species, accounting for 20,62%). Other groups are low diverse.
The Shannon-Weaver Index of zoobenthos is 4,59. Density of individual ranged about 20,62 ind/m2. The medium biomass of zoobenthos was 2,88g/m2.
