| Abstract: | Hichirippu lagoon is inhabited by many animals and benthic plants (e.g. Japanese red-crowned crane, swan and seagrass), and is designated as a wetland under the Ramsar Convention. We quantified the nitrogen cycling in Hichirippu lagoon with a focus on food web and mass balance. The fishery yield (bivalves) in this lagoon is estimated at 25 ton/km'/yr, as high as that of the Seto Inland Sea. The aim of this study was to determine the major biological process supporting the high bird's population and fishery yield. We conclude that (1) the mass balance of Hichirippu lagoon is perfect for sustainable use, (2) it is informative to understand ecosystem of Hichirippu lagoon for all who have the same goal as sustainable society. Consequently, we point out that researchers will have to pay attention to not only what happens in polluted area, but also to what we can learn from unpolluted ecosystem. |
