Japan cultures in pinctada (fucata) martensii, pinctada shimizuensis (S.K. and R. Wada, 1953), pinctada chemnitzii (Philippi, 1849), pinctada margaritifera (L., 1758), pteria penguin (Röding, 1798), and pinctada maxima the latter three only in the Ryukus.
China cultures in pinctada chemitzii (Philippi, 1849), pinctada atropurpurea, pinctada nigra, pinctada shimizuensis (S.K. and R. Wada, 1953), pinctada margaritifera (L., 1758), pinctada maxima (gold and silver), pteria penguin, plus several others that are still in the research stage.
U.S.A., pinctada margaritifera and pinctada radiata (so far mostly spat raising in Hawaii), haliotis rufens (mabé production in California).
That's ten. Current production figures have to be patched together since some countries do not compile statistics on pearl production. In addition there are the Philippines with the golden lipped and some silver lipped pinctada maxima and some pinctada (fucata) martensii, Myanmar with pinctada maxima and pteria penguin (also in tissue nucleated), Thailand with pinctada radiata and pinctada maxima. I know that there is at least one farm in Russia that cultures tissue nucleated round pearls in haliotis kamtchatkana. And that are only the most obvious ones.
It has now been translated into English and also gives some production figures. Please state clearly that you want the English version to avoid confusion. As far as the minutiae of pearl culturing are concerned, you find that in the thread everything you ever wanted to know about pearl culturing in the cultured pearls sub-forum. It has a clickable link to the probably most exhaustive study ever written on the subject of culturing marine pearls.
Hi. This is the qmail-send program at smtp.highstream.net.
I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out.
Sorry, I couldn't find any host named gz-journal.de. (#5.1.2)
I heard the Strack book has become the new Harry Potter. The above contact e-mail is actually the one printed in the book. Jeremy posted a new contact for the publisher under the (misspelled) Strack book thread.
