Giant Clam farming: potential benefits for islands & atolls?
To see the costs of production for Giant Clam seed, you can download the pdf file from this site:
These costs estimates from C.A.Tisdell are based on practical results obtained in the late eighties by Phil Dor, first manager of REEFARM in Cairns Australia and present founder of the Tridacna Mariculture Development Center (TMDC).
The seafood markets for Giant Clams in Japan, China, Korea & Taiwan are large enough to be supplied by hundreds medium sized farms from suitable locations in the Asia-Pacific region. For the Japanese & Korean live in-shell markets, the only conditional limitation for the farm is the close proximity to an international airport within an 8 -10 hours flying time range from Japan/Korea.
As for the Chinese/Taiwanese markets of processed adductor muscle, dried mantle meat and large shells of T.Gigas & T.Derasa, the farming of these clams has the unique advantage that the nursery and grow-out phase can be managed in any suitable remote location which presently have little or no sources of income.
The collecting of hundreds of thousand of Tons of ancient T.Gigas shells from the bottom of the South China Sea by Hainan fishermen for 20 years and the natural reproduction of many millions of T.Maxima clams in Polynesian atolls & islands are the perfect examples that a farming project is not only possible but actually very feasible.

Here below are Google satellite pictures of some other suitable farming locations in the Indo-Pacific region:
Coron in the Philippines, near Kupang in West Timor, Morotai in the Moluccas, Munda in the Solomon islands, Saipan in the Marianas.
Many more locations like the Maldives, Seychelles, Mauritius, Andaman islands, Comoros, Myanmar, Vietnam , Vanuatu, Fiji, Papua New Guinea, Sunda islands in Indonesia etc would be suitable and the potential seafood markets are presently unlimited.
