Outline of Final Research Achievements |
Goby (Acanthogobius flavimanus) has nest in soft saline bed in 6-8m deep water in winter, and hatched larvae swim up to upstream limit of estuarine environment and settle on sandy shallow bed in spring. It becomes 6-8cm in early summer and growing up to 15-20cm in autumn. Public participated census for Gobies and numerical hydraulic simulation of canal network in Tokyo bay reviles severe environmental condition in summer prevent proper succession and growth of gobies. Based on the monitoring results and simulated circulation, a conceptual model for the habitat restoration is proposed. One measure suggested is a construction of a small scale habitat in canal network. That is one of typical hardware type countermeasures. The effects of the construction have been tested by monitoring at constructed tidal-flats. It seems tidal-flats are acting as considerable habitat for Gobies.
