Abstract

 Artificial tidal flats are constructed using dredged soil with high silt-clay content at port channels and anchorages, but the way of constructing as habitats of short-necked clam hasn’t been established. Experimental tidal flats were constructed in Ariake sea to investigate the positive effects of these habitats on short-necked clam populations. Temporal variations in survival rates could be estimated from the monthly total sulfide in the bottom sediments and the condition factor of clam.
