We estimated aboveground primary productivity of Salix nipponica based on biomass using allometry and basal area at Janghang wetland in Han River estuary. In addition, we estimated secondary production of sesarmine crab (Sesarma dehaani) living under the Salix community to interpret relationships between Salix nipponica and Sesarma dehaani. Salix nipponica showed primary productivity of 4,777 g DW $m^{-2}yr^{-1}$, which appear to be the highest primary productivity in South Korea. The estimated amount of autochthonous organic matter from S. nipponica and allochthonous organic matter from the Han River into sediment was 359 g C $m^{-2}yr^{-1}$ and 347 g C $m^{-2}yr^{-1}$, respectively. The secondary productivity of Sesarma dehaani was 100.2 g FW $m^{-2}yr^{-1}$, which was 2.1% of the primary productivity of S. nipponica. The biomass of Sesarma dehanni was average 140 g FW $m^{-2}$, which consumed their prey of approximately 2,140 g FW $yr^{-1}$, which is equivalent to approximately 208 g C $m^{-2}yr^{-1}$.
