| Outline of Final Research Achievements |
Clam siphons are regenerable food sources for juvenile flatfish species. To evaluate the productivity and contribution of clam siphons for flatfishes, field surveys and experiments were conducted. Clam siphons were consumed by flatfish juveniles with a small proportion in Hiroshima Bay, while those were important food items for the juveniles in Sendai Bay. It was first revealed that clams with short siphons such as Asari can regenerate lost siphon tissues quantitatively, although its siphon regeneration rate is lower than that of long-siphoned clams.
