The Gold Coast of Queensland lived up to its reputation of golden sandy beaches, palm trees swaying in the breeze, good surf, sunny skies, warm winter days, blue spiny crayfish, beau-tiful rainforests and good old fash-ioned Aussie hospitality over the week of 30th July – 4th August.
IAA 16 was one of the smaller IAA symposia with over 60 delegates at-tending from over 10 countries. Thirty-nine oral presentations were made and 10 poster presentations were dis-played. The symposium started on Sun-day evening beside the pool at the symposium venue (The Courtyard Mar-riott - Surfers Paradise Resort), with registration, welcome drinks (a-lot of
them) and a buffet/BBQ that included about 250 very tasty redclaw. The oral sessions commenced on Monday morn-ing with a welcome from James Furse
(that‘s me) and the IAA16 team, IAA President-Elect Catherine Souty-Grosset, followed by Alastair Richardson who presented a splendid Host Country lec-ture.
On Monday we were fortunate to have a number of day-delegates from the Queensland Aquaculture Industry, so the majority of Mondays oral pres-entations were devoted to aquacul-ture, fisheries and ecology.
Tuesday‘s sessions were devoted to

Dear IAA members:
It is an honor for me to become President of IAA and I am discovering that I have the same story as our Imme-diate Past-President, the dynamic Fran-
cesca Gherardi! We both attended our first IAA symposium in Thunder Bay (1996). Since then, it has always been a great pleasure for me to meet research-ers aware of crayfish biodiversity in Augsburg (1998), Fremantle (2000), Queretaro (2002) where I was proud to be selected to give the Sture Abra-
hamsson Memorial Lecture, London (2004) and IAA16 on the Gold Coast.
As IAA is the opportunity to meet people who have common interests, it is certainly in part due to the Association that I was able to propose the successful European Project CRAYNET involving eleven countries.
In this issue, you will find an overall view of the wonderful meeting organ-ized by James Furse, who was elected President-Elect (see the election results, pg 17). I want to inform James that Francesca took the opportunity of the first European Congress of Conservation Biology ‗Diversity in Europe‘, held in Hungary, to give me the precious cray-
fish fossil, now in safekeeping in my office. I also want to underline how hard our elected secretary Jim Fetzner is working to establish a new and perma-nently updated website, to help the president with electronically editing Crayfish News and to make more avail-able recent issues of Freshwater Cray-fish.
Since IAA16, I have had already signed two letters. You may enjoy the text of both letters in this issue, setting out exactly the primary role of such an association: the IAA meeting at the Gold Coast resolved to send a letter in favor of a Recovery Plan for the Giant Freshwater Lobster Astacopsis gouldi. Alastair Richardson drafted the letter with the great help of Stephanie Peay's notes (U.K.)(see pg 15). The letter has gone urgently to the Federal Minster for the Environment, and was then cop-ied to the Tasmanian Premier and his two relevant ministers. The second let-ter (pg 18) was sent to the University of Kuopio, Finland (Paula Henttonen and Japo Jussila), confirming that the IAA board has elected the Institute of Ap-plied Technology and the Crayfish Inno-vation Centre (Ari Mannonen) to be or-ganizers of IAA 17 in August 2008.

cidentally, the first time I saw the new president re-ceiving the crayfish fossil in Thunder Bay (1996) it was Paula Henttonen. The Finnish team has an excel-lent leitmotiv: ―IAA meeting has been done before: IAA3 was organized in Kuopio in 1976 by Ossi
Lindqvist (President in 1978 and Honorary Member of the IAA), the tradition is there and Ossi is still going strong‖. I hope the letter will be a good help when looking for the necessary funds from many sponsors.
I remind you that another urgent task is to solve the problem of editing Freshwater Crayfish; don‘t hesitate to give your point of view for further discus-sion, knowing that we need to have a solution very urgently; in Australia, some ideas were submitted but each IAA member has to express his feeling. James Furse assumed that FC16 will be published and a proposal was made in the IAA board meeting and brought up at the general assembly that future IAA symposium registration fees should include clearly the cost of publishing Freshwater Crayfish after the meeting. Arnie Eversole proposed that there should be a managing editor for FC to help organize and keep the publication schedule on track; this seemed to have approval by those in attendance at the IAA16 assembly.
As you see IAA has many challenges, but this is
really exciting! H

ecology, conservation and management, and during all breaks between all sessions delegates were treated to lots of great Australian food and drinks. In fact the only (and frequent) complaint from delegates was that it was going to take some time to work off all the extra bodyweight added at the symposium).
Wednesday was the symposium day-trip, and the destination was the World famous O‘Reillys Rainforest Guesthouse in the World Heritage Listed Lamington National Park. In addition to the symposium delegates we were most fortunate to be joined by the main sponsor, Director of the Centre for Innovative Conser-vation Strategies (CICS), and the Head of the School of Environmental and Applied Sciences (EAS) Griffith University: Clyde H. Wild, and his son Seanan J. Wild. Clyde kindly provided a most informative commentary en-route to our destination, and our bus driver Noel did a fabulous job of negotiating the steep, very nar-row and winding mountain roads. Well done to Noel as it was his first ever trip to O‘Reillys, and he man-aged it in a bus without 2nd and 4th gears – how he managed that feat on those roads escapes me! Every-one on the day trip was treated to some truly remark-able vistas, rainforest, and a very close look at some stunning birds that included Regents and Satin Bower-birds, Crimson Rosellas, King Parrots, and Scrub Tur-keys. After lunch delegates headed off on a walk down into the Toolona Creek Gorge via Picnic Rock to Elabana Falls, during the hike down Shawn Leckie and Jason Coughran (Southern Cross University-NSW) cap-tured a small red crayfish (that was not identified on the day). It was nothing short of remarkable that we managed to lure 2 medium sized (~70 OCL) male speci-mens of Euastacus sulcatus from their refuges and catch them for closer inspection, typically E. sulcatus of this size are simply not active in early August. Well done Premek Hamr on a fine job of catching the 2nd specimen by hand! It was also remarkable that not a single delegate discovered just how powerful, and painful the chelae of this species can be – so many fin-gers, so very close to a painful memory of Lamington National Park and E. sulcatus. A brisk walk back up to O‘Reillys it was back on the bus and back to the Gold Coast.
We really were lucky on that day-trip, the weather behaved itself, we saw some crayfish (and no injuries to man or beast), no-one got lost, no-one was stung by the giant stinging trees, nor bitten by the venom-ous snakes or spiders, no-one picked up a tick, not even a leech – remarkable!
The oral sessions continued on Thursday and the symposium banquet was held on Thursday evening. A

All of the presentations at IAA16 were of the very highest quality and the organisers of IAA16 extend their thanks to the Judges (Alastair Richardson, Cath-
erine Souty-Grosset, and Clive Jones) who were faced with a very difficult task indeed given the quality of all the presentations.
Friday, the final ½ day of the symposium, com-menced with morning tea (at 10 AM) and the days activities included the IAA general assembly, welcom-ing Catherine Souty-Grossest as the new IAA President (and handing over the interim IAA fossil crayfish-kangaroo ―thing‖), some very kind words from Mar-
tin Moore to the IAA16 team. Martin also presented myself with a very nice crayfish hat. The final surprise(?) presentation of the symposium was made by Japo
Jussila (and team), which of course was the bid to host IAA17 in Kuopio (Finland) in 2008. In addition to being the very worst kept secret of the week, the IAA17 bid was fabulous and very well received by all
delegates present. The final scheduled activity of IAA16 was to sit down to lunch and eat more food, before bidding farewell to other delegates.
A final few words from James. On behalf of the IAA16 team (including CICS and the School of EAS - Griffith University), I would like to extend our sincere and deep thanks to all delegates who made the of-ten long (and often expensive) journey to attend IAA16: it simply would not have been possible with-out your support. We have received many wonderful and kind messages of thanks from all over the World – thank you all! It was simply our very great pleasure to have you all come and visit us here, where we live and work – our home! You will always be welcome here on the Gold Coast of Queensland and of course at Griffith University. We shall remain more than happy to organise, and host, another IAA Symposium in the future here in Southeast Queensland – we en-joyed IAA16 too!
The first official call for papers to be considered for inclusion in Freshwater Crayfish 16 will be made via e-mail in the near future. However authors are invited to submit papers (as a MS-Word attachment) at anytime to the following address:
Our very best regards to you all,
James, Clyde and the IAA16 Team

Low Yields Reported for the Louisiana Crayfish Season and Some Possible Causes
Crayfish yields in Louisiana for the previous year were very dismal. The capture fishery from natural habitats was nearly nonexistent, lasting only a few days and from a small confined area of the vast habi-tat. Yield of farm raised crayfish in Louisiana for the 2005-2006 production season was abnormally low also. Though the formal estimates will not be avail-able until early 2007, some have estimated the farm production at only 40 to 50% of normal. Greatest yield reductions seem to be with those farms that culture crayfish behind rice using a field rotation ap-proach. This strategy, involving a majority of the land devoted to crayfish production in Louisiana, is most susceptible to yield adversity because popula-tion densities are typically lower than in ponds per-manently dedicated to crayfish production. When crayfish are not cultured in the same pond during consecutive production seasons, there is little oppor-tunity for the build-up of populations and de-synchronization of reproduction cycles within the population – both aspects that tend to mitigate some environmental related impacts. Therefore, unfavor-able weather patterns or other environmental condi-tions that impact crayfish broodstock survival and/or reproduction generally have a greater impact on crayfish production systems that employ the field ro-
tation approach.
While inadequate overflow from the Mississippi River drainage system negatively impacted the cap-ture fishery, farm production was largely impacted by local environmental events. The storm surge from Hurricane Rita (September 2005) accounted for a di-rect loss of about 8% of the state‘s production area and indirectly affected additional operations. How-ever, it is surmised that a prolonged drought that existed during the summer and autumn of 2005 had the greatest negative influence on crayfish produc-tion state-wide. Drought conditions while crayfish are confined to summer burrows can hamper survival and reproduction of broodstock critical to the re-population of ponds. Some data was gathered at the LSU Agricultural Center‘s Rice Research Station that supports this assumption.
During the summer of 2005, 1 month following pond draining, 260 burrows were hand excavated and crayfish were retrieved, water volume and bur-row depth recorded, and location of the burrow en-trances were noted. Unexpectedly, 45% of the bur-rows contained no living crayfish after only one month of summer drawdown. Dead crayfish were generally associated with burrows containing no measurable water, and there was a strong positive relationship between the amount of water present and burrow depth. Crayfish burrows with entrances at or above the pond‘s water line (likely pre-drain burrows) contained over twice the mortalities as those with entrances on the pond bottom (post-drain burrows). Drought may hasten the disappearance of
water perched inside crayfish bur-rows by facilitating cracks in the soil near the surface allowing evapora-tion (Fig. 1). Burrows constructed earlier and/or on the upper levels of the pond levee may be more condu-cive to cracking and/or wicking. These findings suggest that the un-usually dry conditions during 2005 in Louisiana may have been a sig-nificant factor in negatively impact-ing subsequent crayfish yields.

IAA16 General Assembly Minutes 5 August 2006
James Furse: Initial discussion began with an over-
view of the status of past volumes of Freshwater
Crayfish.
Jim Fetzner: FC14 — status still unknown. No con-
tact from Pedro. Presumably the volume has been
published in both paper and electronic formats, but
no one has received a copy. Repeated e-mails to
Pedro have gone unanswered. Jim suggested that
authors of papers in FC14 be contacted, since all
authors presumably received PDF copies of their
papers. These PDFs could then be made available
on the IAA website for members. ―We might not
be able to assemble the entire volume, but some-
thing is better than nothing….‖ [Editor’s Note: All
FC14 authors have been sent an e-mail asking for
the PDF of their paper. If you have not received
such an e-mail, the address we have for you is out
of date in our database. Please send your PDF file
from FC14 to Jim Fetzner (see e-mail address on
page 19), and also take the time to update your
contact information by logging in to the IAA web-
site].
FC15 — The problems with FC15 (no sequential
page numbering for articles, spelling errors, etc.)
mentioned by many IAA members have now been
corrected by Fetzner and the updated files have
been uploaded to the IAA website for download.
Individual papers, the entire volume, or an updated
CD can now be downloaded directly from the web-
site.
James Furse: FC16 — ―FC16 will be published !!‖
Talk of getting funds from Queensland govern-
ment, etc., to cover publication costs.

A proposal was made in the IAA board meeting, and
brought up in the general assembly, that future IAA
symposium registration fees should include the cost
of publishing Freshwater Crayfish after the meeting.
Arnie Eversole: Proposal to have a managing editor
for Freshwater Crayfish to help organize and keep
the publication schedule on track. This seemed to
have approval by those in attendance at the assem-
bly.
Catherine Souty-Grosset: IAA Finance Report. Cath-
erine reported on funds available in European and
Australian accounts, but had not received informa-
tion from other accounts and the IAA Secretariat.
This information should appear in the next issue
(December ?) of Crayfish News.
General Discussion on IAA Publications:
It was suggested that Freshwater Crayfish should al-
low for the publication of crayfish-related papers not
actually presented at the conference. It was also sug-
gested that an advertisement be placed on the CRAY-
FISH-L list server to announce the fact that FC is an
outlet for publication of crayfish papers. Chris Taylor
brought up the fact that previous issues of FC have in
fact published such articles (i.e., those not actually
presented at the symposium).
It was suggested that abstracts of FC papers be
posted to the IAA website so that they can be easily
viewed and or searched by Google, etc. It was also
suggested that PDFs of FC papers be posted to the
website for download by members. Jim Fetzner men-
tioned the previous reservations about doing this,
mainly that paper copies still exist for some issues
and the costs of printing will not be recovered if PDFs
are made available online for free. Additionally, the
time involved in retrospectively capturing past vol-
umes is daunting. Chris Taylor asked if past volumes
have been indexed by indexing services. Jim Fetzner
indicated that he believed that they had, but was not
sure about FC14/FC15.
It was suggested that maybe pre-ordering of FC
volumes by conference attendees and/or a limited
―first-run‖ of FC volumes may be a way to save on
publication costs.
It was then suggested that the IAA board or a
selected IAA committee be organized to discuss issues
related to the publication of Freshwater Crayfish.
Further discussion on the topic was suspended.
Japo Jussila: Finland Presentation for IAA17
When – August 2-5, 2008
Where – University of Kuopio, Kuopio, Finland
Presentation to James Furse for hosting IAA16. James
received a ―crayfish hat‖ and free registration for
IAA17.
James Furse: Membership Fees. James asked if the
IAA should increase membership dues, but it was not
mentioned what these increases might be and why
an increase was sought, so there was not much dis-
cussion on the topic.
Stephanie Peay: Suggested the submission of a letter
from the IAA to the Australian and Tasmanian gov-
ernments to adopt conservation efforts to protect
Giant Tasmanian Lobster habitat, and to help the ef-
forts of member Todd Walsh. A vote was taken, and
everyone in attendance agreed that such a letter
should be sent. Alastair Richardson volunteered to
write the letter outlining the issues, etc. (see pg 15).
He will send a draft around for comments and Cath-
erine will sign it for the membership. The draft will
also be posted to the IAA website so members can
comment on it before it is signed. The letter will be
needed before September 2006, as crucial proposed
legislation possibly impacting the species occurs at
that time. H

The following pages contain a few letters sent
out by recently elected IAA President, Catherine
Souty-Grosset, in relation to IAA business that
might be of broader interest to the membership of
the society. The first letter, drafted by Alastair
Richardson, relates to the Tasmanian Giant Fresh-
water Crayfish (Astacopsis gouldi) management
plan, and was sent to the Tasmanian and Austra-
lian governments in support of protecting this
amazing species. Also depicted is their reply to the
letter from the Premier‘s office. For those who
would like to sign the online petition to help save
this species, please visit http://iz.carnegiemnh.org/
crayfish/IAA/petition.asp. The remaining letter
(page 18) indicates and confirms the IAA‘s selection
of the University of Kuopio as the host for IAA 17 in
2008. Also in this issue are the results from the IAA
elections and the minutes from the IAA16 General
Assembly Meeting. H

Dear Colleagues,
Last year, I asked you to provide information on
ecological impacts of Cherax tenuimanus, C. quadri-
carinatus and Astacus leptodactylus. Thank you for
those (incl. Prof. Lindqvist and Prof. Gherardi) who pro-
vided informative references or information. The
Ministry of the Environment of Japan has successfully
designated the genus Astacus, Pacifastacus leniuscu-
lus, Orconectes rusticus and the genus Cherax as inva-
sive alien species under the Invasive Alien Species Act.
Live import, translocation and/or release of these or-
ganisms is now strictly regulated under the IAS Act.
http://www.env.go.jp/nature/intro/r_yunyu_e.pdf
Our institute (National Institute for Environ-
mental Studies), a stand-alone institute of the Minis-
try of the Environment of Japan, is trying to educate
the general public not to import or translocate the
invasive alien species or other alien species. Because
the IAS Act is a new law, many people still don't
know which organisms are the listed species and
what the regulations are.
As a part of an exhibition at Tsukuba Expo Center
(Tsukuba, Japan), I am going to present a poster con-
cerning the hazards of alien species on ecosystems,
and exhibit photos of representative invasive alien
species (including both animals and plants). As a
crayfish specialist, I would like to have photos of the
invasive alien crayfish, in particular.
I am specifically looking for photos of Astacus
(especially A. astacus and A. leptodactylus), Orconec-
tes rusticus and Cherax (especially C. destructor, C.
tenuimanus and C. quadricarinatus). If any of you can
provide photos of these species by 28 September,
please let me know.
Digital photos of dorsal or lateral view (that indi-
cate natural body color) without copyright protection
are preferred. I will indicate on the respective photo
the name of the photographer. This exhibition starts
from 1 October 2006 and lasts for one month only.
After the exhibition, I would like to use these crayfish
photos in my private home page introducing in Japa-
nese what the designated invasive alien crayfish look
like (but you can decline this if reluctant). I will not
use photos for any other purposes. I apologize for
such a short notice. I look forward to hearing from
you. H

Atlas of Crayfish in Europe. Souty-Grossett C, Holdich DM, Noel PY, Reynolds JD, and Haffner P. (eds.) 2006. (see cover on page 20).
Crayfish are important as part of our natural heritage and represent key elements in freshwater ecosystems. Their conservation favors the protection of the aquatic environment and water resources and they have a cultural and economic value in Europe. However, the loss of populations in the wild is exac-erbated by the degradation of water quality due to human population pressures. Even if habitats are re-stored and species reintroduced, their effective man-agement requires the understanding of impacts of translocation of non-indigenous crayfish species, par-
ticularly with the spread of crayfish plague.
The first part of this atlas deals with systematics and phylogeny, followed by a general description of habitats and threats in the second part. The third part describes current knowledge of the five indige-nous species, seven non-indigenous species and three recently discovered non-indigenous species. The fourth part deals with diseases and the fifth part de-scribes conservation and management, including education and legislation. The final part is intended to generate awareness of indigenous stocks.
Basic information are thus widely available across Europe, both for administrators and the general pub-lic. A bibliography, a glossary and a species identifica-
tion key complete the volume. H

Starr is fast becoming a paragon of contemporary Australian art, both in
Australia and around the world. With successful exhibitions around
Australia as well as in New York and Singapore, she is carving a niche for her-
self, with an instantly recognizable and thoroughly original style.
Her work explores the warmth and passion of life as an artist, and Starr
captures in paint what the camera seeks to fix in a moment of time. Starr
creates works that become contemporary icons. Her subject matter is both
familiar and universal in appeal. The lush layered surfaces are worked with
fast-saturated color and include her signature calligraphic line that traces

Researchers See Hope For Ridding Lakes of
Rusty Crayfish
The rusty crayfish – a voracious, bullying exotic that
has visited ecological havoc on numerous Wisconsin
lakes – may have finally met its match.
―They pretty much wipe out all of the rooted
aquatic plants, they eat fish eggs, they either eat or
compete with native invertebrates and, in general,
raise havoc with the near-shore community of a
lake.‖ said Stephen Carpenter, a University of Wis-
consin-Madison professor of limnology and zoology
involved in a study on Sparkling Lake in Vilas County,
Wisconsin.
The long-term study of the feasibility of evicting
the rusty crayfish from the 110-acre lake is now in its
sixth year. Since 2001, the Madison researchers, aided
by a small army of undergraduate students and the
Wisconsin Department of Natural Resources , have
succeeded in significantly reducing the population of
rusty crayfish in Sparkling Lake through a program of
intensive trapping targeting the largest crayfish and
manipulating fishing regulations to favor the small-
mouth and rock bass that dine on juvenile crayfish.
The two-pronged attack, says Carpenter, has yielded
very promising results.
―It seems to be working. The aquatic plants are
back. That‘s good because that‘s fish habitat, and the
fish populations are returning to what they were be-
fore the rusty got into the lake sometime in the
1980‘s,‖ said Carpenter. The hope is that the experi-
ment will expose a ―tipping point,‖ where the fish
alone can keep up the pressure. H

New Species of Procambarus described from Louisi-
ana, U.S.A.
A new species of crayfish from the genus Procamba-
rus was described in a recent issue of the Proceedings
of the Biological Society of Washington (See Walls
reference in ―Literature of Interest to Astacologists‖,
page 22). The new species is only known from Ford-
ney Creek, Caddo Parish, Louisiana.

Endangered Crayfish Colony Found
Britain's only native crayfish, which was
feared extinct in Essex, has made a comeback.
Essex Biodiversity Action Plan environmentalists
have discovered a colony of white-clawed cray-
fish thriving in the River Chelmer. The survey
found 18 of the crustaceans from mature cray-
fish to babies. The species has been wiped out in
many parts of the country by the non-native lar-
ger American signal crayfish with whom they
have to compete for food.
Project officer Mark Iley said: "It's the only
site in Essex where we know that we have these
white-clawed crayfish." The crayfish play an im-
portant role in the aquatic food web, providing a
food source for a variety of animals such as fish,
birds and mammals such as the otter. They like
clean water and shelter in crevices under sub-
merged stones, tree roots and plants. "We will
be improving their habitat by putting in rocks
and wire baskets to provide a refuge for them.
"It's good that we have got a positive site but we
now have to protect it," said Mr Iley. In addition
to displacing the native crayfish, the signal cray-
fish also carry a plague, a fungal disease that is
deadly to British animals.
