| 内容記述 | This research was carried out to investigate the feasibility of using dredged sediment (DS) as the additive of silt and clay for artificial tidal flats. A series of experiments conducted in the real seashore and in a tidal flat simulator demonstrated that DS could be used for artificial tidal flats. Furthermore, the tidal flat simulator experiment showed that the macrobenthos population increased with the DS addition. However, use of conditioners made of paper sludge and poly-aluminum chloride for DS granulation treatment was associated with a time lag in the growth of the macrobenthos: these agents may be released during the course of the experimental period. Possible reasons for the increased polychaete and gastropod abundances in the artificial tidal flats might be an increase in supplied organic matter and stimulated benthic microalgae growth due to the DS addition. Finally, a growth test was carried out for the short neck clam Ruditapes philippinarum, which showed that it can grow in artificial tidal flats to which DS has been added. Too much DS, however, may suppress its growth. | |||||
