The species of Ruditapes variegata usually inhabit in sandy-mud bottom,
these mainly distributed in intertidal, sub-tidal, sand mudflats or sandy
beach. Recent years, shallow water aquatic resources are serious
exhausted day by day, we have been hoping to restoration the resources by
this study. In order to establish important basic information for this
clams that artificial propagation and breeding will be conducted. This
project is to study artificial propagation techniques of the clams and
their biochemical composition annual variation of offspring, and observe
the effects of the salinity fluctuation on hatchery larvae.
