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-... [or go to blurb.com and search for SAVING GIANTS]
On July 15, 2010, our good friend and longtime colleague Bill Fitzgerald visited PMDC, the Palau Mariculture Demonstration Center. PMDC is the facility formerly known as MMDC, the Micronesian Mariculture Demonstration Center.
Bill, now retired and sailing the Pacific and Caribbean, is the former director of GADCTC, the Guam Aquaculture Development and Training Center.
Bill met with PMDC hatchery manager Lawrence Sumor, a longtime Clam Project employee of PMDC and MMDC. Bill filed this report with us via email on 8/21/10, and included four photos he took at PMDC on 7/15/10:
"The clam project continues. Lawrence [Sumor] is running it. He said to say hello to you. The production is going to local farmers that have leased areas on the reef."
"Becky [Madraisau] passed away about two years ago; however I met his son (Murphy) who now operates the fish culture section. They apparently had one successful spawn of a grouper, but could not repeat it."
I (G. Heslinga) can also report a meeting this month (Aug. 2010) at Indo-Pacific Sea Farms in Kailua-Kona, Hawaii, with one of the major West Coast marine aquarium livestock wholesalers who is currently working with Koror State, Selestino "Endamo" Otong and local Palauan clam farmers to keep ample supplies of cultured giant clams flowing into the US aquarium markets.
Mahalos to all for the recent reports. We send our deepest condolences to the family of Becky Madraisau. Beketaut worked for three decades at MMDC/PMDC, mainly on hawksbill turtle and rabbitfish culture, dating all the way back to the days of Tosh Paulis, Pat Bryan, Bob May, Pete Wilson, Masashi Yamaguchi, Steve Jameson, Bill Hamner, Frank Perron, Jim McVey, Bruce Saunders, Bob Johannes, Doug Faulkner and many others. Becky assisted us all on occasions too numerous to count. He will be remembered; he will be missed.
