Abstract:Species composition, distribution, standing crop biomass, spawning,
and growth rate of Tridacnidae clams were studied in Palau, Western Caroline
Islands. The population was composed of six species: Tridama gigas, T. derasa, T.
squamosa, T. maxima, T. crocea, and Hippopus hippopus. In random transects, T.
crocea was the most frequent and abundant, while T. derasa and T. gigas made up
the largest proportion of the standing crop biomass. Spawning was induced
artificially in T. squamosa by addition of macerated gonad from one individual to
an aquarium containing other individuals, but larval development was not observed.
The growth rate of tagged Tridacnidae was slow and further study will be required
before an estimate of biomass production can be derived.
