Barito Kuala district is a region that is mainly composed of tidal marsh. The Marsh area is a crucial area for agropolitan development of fisheries resources. With the current issues of land use converted function, we need to assess the sustainability level of the marsh area. This study aimed to assess the sustainability of tidal marsh fishery resources in the Barito Kuala district based on five dimensions of sustainability, i.e. ecological, economic, socio-cultural, technology, as well as legal and institutional dimensions. We used Multi-Dimensional Scaling (MDS) approach which was called Rap-Batola and the results were expressed in the index and status of sustainability. The results showed that the Kuripan Sub-district has the highest sustainability index (59,37) compared to the Marabahan Sub-district (59,27) and Carbon Sub-district (58,21). However, in general, it can be stated that the fishery resources of tidal marsh in three sub-district areas were quite sustainable. Thus it can be stated that the fisheries resources of tidal marsh in the Barito Kuala district have sustained sufficient status.
