Our beautiful new 222-page ebook, SAVING GIANTS: Cultivation and Conservation of Tridacnid Clams (by Gerald Heslinga, 2013) is now available for download http://store.blurb.com/ebooks/374835-...

Now 27 years old, the specimen was produced at the Republic of Palau's MMDC Giant Clam Hatchery by Gerald Heslinga and Frank Perron and taken to the Waikiki Aquarium in 1983 by Dr. Bruce Carlson. At the time this clam was transported to Hawaii it was just 1-2 centimeters long -- about the size of a human thumbnail. • This Tridacna gigas specimen has been maintained in good health in captivity in Hawaii for nearly three decades without feeding, thanks to the skill and dedication of the Waikiki Aquarium staff. It has been viewed by some 5-10 million visitors. • Giant clams are known to derive all or nearly all of their nutrition from zooxanthellae, the photosynthetic algal partners living within their tissues. No feeding of captive clams is required if they are raised in a thriving community of reef organisms including fishes, as seen in this video. The clams are able to absorb essential dissolved nutrients such as nitrogen and phosphorous, which are metabolic by-products of the fishes and other organisms in the reef community. • In the early 1980's Palau's MMDC Giant Clam Hatchery became the first laboratory in the world to achieve successful commercial-scale mass production of tridacnid clams. During the next 10 years giant clam breeding technology spread widely and rapidly throughout the tropical Asia-Pacific region. • The MMDC played a central role in the successful transfer of giant clam breeding technology around the Indo-Pacific region, as did Australia's James Cook University giant clam mariculture project, initiated in 1984. The JCU project was funded by ACIAR, the Australian Centre for International Agricultural Research, while the MMDC's work was funded primarily by the US National Marine Fisheries Service (NMFS/NOAA), the University of Hawaii Sea Grant program and the United Nations Food and Agriculture Organization (UNFAO). • Selected MMDC References: • Beckvar, N. 1981.
