maxima in Taiwan

Tridacna maxima are a widely distributed giant clam species in the world. Recently, several studies have shown that a cryptic
species, i.e. Tridacna noae is similar to T. maxima based on morphological and molecular sequence evidences. The aim of this
study was to compare the reproduction and growth of the two giant clams. Based on field monitoring on eggs, the spawning peak of
T. maxima was fromMay to August in Kenting, and March to June in Dongsha. In T. noae, it was through May to July in Kenting, and
April to June in Dongsha. Artificial fertilization was successfully conducted in T. maxima and T. noae. By comparison, the growth
of juvenile T. maxima was faster than that of T. noae under cultural conditions. And, the growth of both species was faster at higher
temperature (27-29°C) than the lower ones (24°C). Based on the cultural records, the growth ring on shell and hinge plate of the giant
clams from cultural and wild populations were also compared and contrasted.
Biography
Hei-Nin Kwong works on giant clams especially the growth comparison between field and cultural environments. He had the first attempts to apply alizarin red staining
method on giant clam shells which is commonly used in coral studies.
