The coastal fishes were investigated from 03/2018 to 01/2022 by trawlnet, stow-net, and gill-net boats. The results showed that there were 122 fishes identified belonging to 45 families of 17 orders. There were 64 species of the Perciformes (sharing 53.3% of the total) and the others were Clupeiformes with 15 fishes (12.3%), Pleuronectiformes with 11 fishes (9.02%)
and other orders with only from 1 to 6 fishes (0.82 - 4.92%). Fish composition in different sampling sites of Soc Trang - Bac Lieu coastline was similar, but there was different number of species among the estuary areas in months of theyear, and in different years
the highest number of species was found in November (at Tran De and My Thanh estuaries) and in July (at Nha Mat estuary). There were some fishes rarely found such as Otolithoides biauritus, Scomberoides lysan, Netuma thalassina, and Leptomelanosoma indicum. The fish composition of Soc Trang and Bac Lieu coastal regions was diverse and rich.
