Tidal flat production mechanism of the juvenile Japanese littleneck clam and measures to secure a healthy bay and restore clam catch size
- Project Description
As the Japanese littleneck clam catch continues to decrease, the population of juvenile clams in Mikawa Bay, which comprises 60% of Japan's total littleneck clam catch, is facing destablization as a result of upwelling-driven hypoxic conditions. In this study, we elucidate the mechanism of the mass production of littleneck clam through on-site observation and experimentation in the Rokujo tidal flats, the sole known location for mass production of the juvenile clams. We also present a new basic outline on the structure of artificial tidal flats and locations for their deployment.
