An assessment on the fishery and socioeconomic status of fishing communities at the Thanlwin River Estuary, Mon State has been conducted within the period of 2015-2018 especially at Kalwe and Ahlat Village tract, at Belukyun Island which is situated at the mouth of the Thanlwin River. The  regions  are  well-known  for  brackish  and  marine  water  fisheries  even the mudflat fisheries as well. The common fishing gears employed in this area are beach seine net, bag net, and the drift gill net. A total of 24 species of brackish and marine fishes were recorded from the estuary. Group interviews were conducted with local peoples, along with surveys into the fishing areas. Among the recorded fish species, the brackish fish species of Polynemus paradiseus (Paradise threadfin), Tenualosa ilisha (Helsa) and Johnius coitor (Coitor croaker) are the important commercial fishes found around  the  estuary. The estuarine environment is experiencing the rhythm of dynamic hydro-sedimentation such as alternate erosion and accumulations mostly at the river mouth epically near the Belukyun Island. Local  fishery communities  are  trying  to  adapt  to  the  environmental  and  consequent  changes  of  socio economy and livelihoods. Unfortunately, local  communities  are nowadays facing  the  problems  of  yearly  depletion  of  fish catches  around  these  areas.  According to local information, some  fish species  are  on the  verge  of  complete  disappearance,  some commercial  species  have  become  rare  and  some are  now  totally  vanished  from  the  area. Accordingly the socio-economy status of the region also is changing among the local communities. So that, enhancing the aquaculture system within the country is become important issue and need to introduce the technology within the possible regions.
