Japan Sea collecting

September 22, 1999
From: Shigeru Hayashi

Dear Dr.Rudman
Here is our first contribution.

We are an amateur group, the Takaoka Biological Club, which has been investigating and studying Opisthobranchia continuously on the Japan Sea, since 1950, receiving guidance from Dr. Baba and Dr.Hamatani. We are at present putting in order all the information that we have accumulated over the past 50 years and we would like to contribute information on the Japan Sea to your site.

By the way, we carry your site address in an article of our magazine JANOLUS No.100. I am in charge of the public relations of our group. We are at present wrestling with the problems of making a web page.

Best wishes,
Shigeru Hayashi

Dear Shigeru,
Your message is very welcome. I have often noticed in the publications of Dr Baba and Dr Hamatani, the contributions Biological Clubs have made to their studies, in finding interesting specimens and making important observations on aspects of the natural history of opisthobranchs.

I would like any information and photos you would like to share with us. The work of Dr Baba and others have made the Japanese fauna particularly important to other workers in other parts of the Pacific because he has described so many species. While many of these species are easy to identify from his descriptions and published illustrations, some are more difficult to determine. Photos then of even the most common Japanese animals would be of great value in helping us to understand your fauna and to understand how much variation occurs in particular species throughout the region.

Your separate message on Elysia abei is a good example. Although it is obviuosly very common in Japan, I have never seen a photo of it. We have a number of unnamed species of Elysia in eastern Australia, and I will now be able to compare them with your photograph to see if this species also occurs in Australia.

I look forward to further contributions from your club,
Best wishes,
Bill Rudman.

Dear Dr. Bill Rudman

Hello, How do you do. My name is Rie Nakano. I'm webmaster of 'Diver's Street' (Japanese website), [http://www.street.ne.jp/divers/home.htm]
and editor of Mr.Atsushi Ono's book 'OPISTHOBRANCHS of KERAMA ISLANDS'. This book will published by TBS-BRITANNICA Co.,Ltd.

Mr.Ono gathered over 300 species of opisthobranchs in Kerama Islands (Kerama Islands is near Okinawa, near Mr.Bob Bolland's field), and he will have just 300 species in this book.

It will published in mid-June. But he can't determine scientific name for several species yet,

Can you help?

Dear Rie,
I am happy to look at your unknown species and help to identify them. If it is ok to put the pictures on the Sea Slug Forum, we will get some added help in identification from those who visit the Forum regularly.

I look forward to seeing the book when it is published and am happy to review it on the Forum and give details on where to buy it.

Best wishes,

Re: collecting in Japan

March 19, 1999
From: Yoshi Hirano

Dear Bill,
Thank you for your kind and quick message. Here is part of my reply to Cynthia about collecting in Japan.
"Dear Cynthia,
I hope I can help you to find some suitable marine labs to collect Placida dendritica in Japan. If you would like to collect them in a real Inland area, you can visit two laboratories in Seto, Inland Sea of Japan, western Japan.

If the Inland area is not necessarily important, you can have more choices. I can give you some addresses you can contact when you give me some idea of your plans

Fortunately or unfortunately, there is no special regulations for collecting opisthobranchs in Japan..."

As to your interest in information from Japan, I am learning to send pictures by jpeg image, so wait one moment. I am happy to send information from Japan!

All the best wishes,

Dear Bill,

I found that Cynthia Trowbridge is looking for collecting sites for her favorite creature in Japan in the Locality Page. I sent some information to her. I learned your sea slug forum is so great and useful for everyone.

I enjoy it very much and would like to collaborate with it as far as I can. Please add my details to the Participants List.

All the best,

Dear Yoshi,
Thanks for your email and I am glad you were able to help Cynthia. Perhaps you could send a copy or summary to the Forum as it may be of interest to other participants. I look forward to any information on Japanese nudibranchs.
Best wishes,

Collecting sites and regulations in Japan

March 10, 1999
From: Cynthia Trowbridge

Dear Bill,

Thank you very much for creating this slug site. Keep up your good work!

I was wondering if anyone could offer me suggestions on collection localities in Japan? I am attending a seaweed (slug food!!!)conference in Hong Kong and then flying back to Oregon via Japan. I am interested in collecting Placida dendritica from the Inland Sea area of Japan. Would anyone be able to give me suggestions of specific localities to visit and to describe the current regulations for collecting opisthobranchs and exporting perserved specimens (for DNA analysis)? I would appreciate any assistance (I am leaving mid June). Thanks in advance for your assistance!

Cordially, Cynthia

Dear Cynthia,
Hopefully someone will be able to help you with information. I would be very grateful if you could give some background information on your research work - with pictures if possible - and a paragraph for the Participants Page.
