It was 1971 when Jon Nelson, a fish biologist with the USFWS, transferred from Bismarck, North Dakota, to Kenai, Alaska. Jon had been active in the Upper Missouri River Chapter of AFS and wanted to continue involvement. In 1972, as he looked about for local AFS affiliation, Jon learned there was no chapter in Alaska, and earlier attempts to form one had failed. He wrote to Robert Hutton, AFS Executive Secretary at the time, for guidance on forming a chapter and received a response from Henry Clepper on behalf of the Society. With directions in hand, Jon began contacting other fisheries professionals for support. Jon credits Chuck Meacham, Sr., then Special Assistant to the Area Director for the USFWS in Alaska, for supporting his efforts by granting official time and resources for planning and organizing. With approximately 100 signatures on a petition to form an Alaska Chapter, Jon sent the petition to AFS with a request to hold an organizational meeting.
On May 22-23, 1974, 25-35 people attended a charter meeting in Juneau where they elected Jon Nelson as President; Jack Van Hyning, Vice President; Al Davis, Secretary-Treasurer; and Chuck Meacham, Jr., Program Chairman. Eight months later, on January 8-9, 1975, about 85 people--90% of the AFS membership in Alaska--attended the first Annual Meeting of the Alaska Chapter at Juneau's Baranof Hotel. Special guests included Jim Brooks, then Commissioner of ADF&G; Dr. Cameron Stevenson, then AFS President, who confessed amazement at the success in attendance; and Senator Ted Stevens, who gave the keynote address and later featured the meeting in his newsletter. The Alaska Chapter was out of the gate at a hard gallop!
The combined meeting of the AFS Alaska Chapter, Western Division, and North Pacific International Chapter and the Lowell Wakefield Symposium is shaping up to be a big, informative meeting with multiple daily sessions. The meeting will be in Anchorage on September 29 through October 3, 1998. The Anchorage Hilton is the host hotel, and we will fill the available meeting space on the second floor and more.
The programs and other details are on the Internet. For the AFS portions, visit http://www.alaska.net/~fishak/98meet.html , and for the Wakefield Symposium, visit elsewhere in this Oncorhynchus.
The registration procedure this year is different from the "usual" Chapter meeting. All registration fees need to be paid in advance or on-site (i.e., no invoices), but Visa and Mastercard will be accepted. A registration form is at http://www.uaf.alaska.edu/seagrant/Conferences/Ecosysframe.html. The form and fees should be sent to Alaska Sea Grant College Program, University of Alaska Fairbanks, P.O. Box 755040-ELT, Fairbanks, AK 99775-5040.
There will be lots going on during this meeting, and you will not want to miss out. Not only will there be more than 20 technical sessions and the usual receptions and banquet, but also a trade show and a tour to the Alaska SeaLife Center. The Wakefield Symposium will add a big international flair, and you will meet the National AFS officers, as well as many of your old (i.e., former) buddies from throughout the Western Division.
The bottom of the bucket... The fall issue of the newsletter is early this year-- not because we think that it will be an early winter. The Annual Meeting of the Alaska Chapter is early this year, and we wanted to make sure that all Chapter members knew when it was and what it was about. By now everyone who reads the newsletter should be aware that this is the first joint meeting of the Western Division, the North Pacific International Chapter, and the Alaska Chapter. Furthermore, it is jointly hosted by the Wakefield Symposium sponsored by Alaska Sea Grant. It will be big, and the scope is all-inclusive. All aspects of aquatic management and research will be covered, from freshwater-terrestrial interactions to marine benthic processes. The list of speakers for the plenary session is impressive and includes distinguished scientists, such as Drs. Stuart Pimm and Richard Beamish, as well as social and political leaders, such as Larry Merculieff of the Alaska Inter-tribal Council, and Terry Garcia of NOAA. The agenda speaks for itself (see the list of papers elsewhere in this issue).
This is a significant meeting for Alaska and all those involved with aquatic resources of the State. A theme that I keep pushing is that Chapter, Division, and National AFS meetings are an important part of professional development. While the technical sessions are important, person-to-person contacts are equally, if not more, important. At most Chapter meetings, these exchanges are among people working in Alaska and a few "outside guest speakers." This meeting is an exception; it will be attended by professionals from throughout the Pacific Northwest. There is no better opportunity for exchanging ideas, concepts, and data among a diverse group of professional biologists and technicians. This is a rare opportunity for those in Alaska. I hope that you all will attend. If you’re within driving distance, attend at least for a day.
I suspect that, since you’re reading this, you are interested in or familiar with the meeting and its significance. Not everyone who is a member will read this column, and few non-AFS members will even see this issue of Oncorhynchus. While we do not expect the circulation of the Anchorage Daily News, we would like to reach individuals who manage, research, or use Alaska’s aquatic resources. If you work with someone who is not a member of AFS, take this opportunity to give them copies of the meeting agenda. This meeting and membership in AFS is an important part of professional development. It is continuing education and an opportunity to reach outside "the box" (i.e., our assigned space in the organization) for new ideas.
This is "the bottom of the bucket," and I will soon become a "past president." I began my term with the theme that membership in AFS was an important part of professionalism in the fisheries and aquatic ecology profession. I hope this theme will remain on "the top of the bucket." A constant and recurring issue among fisheries managers and scientists is that "we are not viewed as professionals" to the same degree as physicians, dentists, (yep, even) lawyers, or accountants. A strong professional society and membership in that society are a common theme. The AFS (including the Chapters) is a strong professional society with international recognition. Are you a member? Bring a friend or colleague to the meeting in Anchorage.
Don’t forget to attend the 15th International Symposium on Biotelemetry in Juneau May 9-14, 1999. For details, contact John Eiler at john.eiler@noaa.gov.
Hey! Were you aware that we have VIP's right here in our Alaska Chapter? These VIP's just go quietly about their business and get their important jobs done. These are the folks who have stepped up and volunteered to help with local arrangements for the 25th Anniversary Meeting of the Chapter combined with the Western Division, North Pacific International Chapter, and Wakefield Symposium. The meeting is shaping up and looking good. These are the people who are making it happen. And if you have any questions at the meeting, they will be there to help you. When you see them, say "thanks!" And here they are: Bill Bechtol (Trade Show Vendors), Allen Bingham (Registration), Jane DiCosimo (Donations and Registration Materials), Valerie Elliott (Local Vendors and Trade Show), Steve Fried (Banquet), Lee Ann Gardner (Banquet), Jeanne Hanson (Trade Show), Carol Kerkvliet (Poster Session, Door Prizes and Raffle), Steve Miller (Banquet Decorations), Larry Peltz (Tours/ Travel Information), Joe Sullivan (Tour Arrangements), Bill Wilson (Hotel Contact), Carol Woody (Raffle, Door Prizes), and Steve Zemke (Audio-Visual Support).
Other people have helped, too. Carol Hepler designed the anniversary logo. Norma Sands, Marla Trollan, and Carol Barnhill are helping with logo applications. And Bill Hauser is helping, too; mainly by keeping out of the way and allowing the VIP's to do their work. If you have some questions about local arrangements for this meeting, you can ask a VIP or contact Bill at 267-2172 or BillH@fishgame.state.ak.us.
How do you like the logo for the Chapter's 25th Anniversary Meeting on the front page? It looks even better in color. It was designed by Carol Hepler. It has been made into a snappy, limited-edition lapel pin. And you can get your very own lapel pin only at the Annual Meeting. Don't forget to ask for yours!
Alaska has an important new resource for research and education that both Alaskans and visitors from the Lower 48 should examine while here for the AFS/Wakefield meeting. The Alaska SeaLife Center (http://www.alaskasealife.org or 800-224-2525) is the only major subarctic, coldwater marine research facility of its type in the world. Its purpose is to provide a research platform for studying marine fish, birds and mammals. The Chapter has arranged a special customized tour of the Center, which will provide a full, behind-the-scenes guided look at the laboratories, research activities, life support systems, and aquaria. For details, see http://www.uaf.alaska.edu/seagrant/Conferences/Ecosysframe.html.
The raffle for this year's Annual Meeting is again shaping up to be a special event. The raffle committee (Carol Woody and Carol Kerkvliet) already has three raffle items: a Sage fly rod (8-wt), reel & box of flies; a very nice tent; and a Ray Troll print. More items are expected to be added. Don't forget that the proceeds from the raffle go to a good cause. This year, proceeds will be donated to the Alaska Chapter Student Unit to be used to support travel to our Annual Meetings. Get your tickets now!
