Lowell Wakefield Fisheries Symposium


October 11-13, 1995
Anchorage, Alaksa, USA

Crab resources remain of high economic importance to Alaska as well as
to other states and nations with exploitable crab populations. Over the
past 20 years crab abundance and harvests have fluctuated widely,
causing economic uncertainty for the industry. These fluctuations also
make it difficult to predict future harvest levels. Stabilization of
harvests or improvements in the ability to predict future abundance of
the resource would alleviate some uncertainty. However, not enough is
known about basic crab biology, especially the processes that regulate
recruitment to the fishery, to accomplish this. This symposium will
bring together the current knowledge on biology, management, and
economics of crabs from high latitude habitats. By building on the crab
data already assembled through this symposium series, sponsors hope to
better conserve the resource; strengthen the industry; and provide
accessible, healthful protein to the consumer.

More than 50 research papers have been accepted for presentation from
Europe, Asia, Australia, South America, and North America. This is the
thirteenth in the Lowell Wakefield Fisheries Symposia series, initiated
by the Alaska Sea Grant College Program in 1982. Previous symposia on
crab focused on Tanner crab (1982), Dungeness crab (1984), king crab
(1985), and king and Tanner crab (1989).

These symposia provide an opportunity for researchers and resource
managers from around the world to meet colleagues they previously knew
only through the literature and correspondence, to renew old
friendships, and make new ones. The sessions will be scheduled to
provide as much time for informal socializing as possible. A reception
for all symposium attendees is scheduled for the evening of Wednesday,
October 11, at the Regal Alaskan Hotel.


The three-day program will begin with registration at 8:00 AM on
Wednesday, October 11, and will conclude with the general discussion
during the afternoon of Friday, October 13.

A light continental breakfast will be available each day just prior to
the morning session. The presentations are grouped into seven sessions.
Program topics are:

Overviews, Management Considerations, and Economics

*	Distribution of golden king crabs in the Eastern Aleutians
*	Ecological features of snow crab in the Sea of Japan
*	Distribution and biology of crab off Kamchatka
*	Distribution and population structure of Dungeness crabs in Alaska
*	Biology of the giant crab in southern Australia
*	Distribution and abundance estimation of red king crabs
*	Use of geostatistics for snow crab stock assessment
*	Molting probability of Dungeness crabs

*	Spawning cycle of the horsehair crab
*	Lithodid reproductive strategy in South America
*	Geographic structure and reproductive activity in opilio populations

*	Energetic costs of molting and egg production in king crab
*	Population structure and fecundity of brown king crab 
	in the Sea of Okhotsk
*	Formation of year-class strength of red king crab off Alaska

*	Compensatory feeding capacity of two brachyuran species
*	Activity and feeding behavior of Dungeness crab in Glacier Bay
*	Correlation between carapace length and body weight

Genetics, Disease, and Mortality
*	Genetic variation in king crab from the Okhotsk and Japan seas
*	Genetic and morphometric variations of snow crab off Eastern Canada
*	Changes following dinospore release from crab with bitter 
	crab disease
*	Effects of handling and discarding

New Fisheries, Fisheries Enhancement, and Conservation Measures
*	Development of artificial reefs for horsehair crabs
*	Biology of the lithodid crab near South Georgia Island
*	Barents Sea king crab transplantation experiments
*	Effects of handling on feeding, activity, and survival of
	red king crabs

Note: These are general topics of presentations, not exact titles. In
addition to the presentations, there will be a general discussion on
future research needs. 

The official language of the symposium is English. Participants who need
interpretation or translation services should provide their own.


A proceedings containing all the presented papers and discussion summary
will be published by Alaska Sea Grant shortly after the symposium. Each
registrant will receive one copy; additional copies will be available
for purchase.

Proceedings have been published for all symposia in the Lowell Wakefield
series and made available for purchase throughout the world. Thus we
have provided information to a much larger audience than just those who
attend the meetings. The proceedings of the Dungeness crab symposium
(1984) and the king crab symposium (1985) have been out of print for
some time. However, the proceedings of the king and Tanner crab
symposium (1989) are still available. The publication contains 53
papers plus a summary of the general workshop discussion, 633 pages in
all. Topic areas covered by presented papers include reproduction, life
history, feeding and growth, population structure and dynamics,
mortality, and stock assessment and management. Copies are available
for purchase.


The symposium will be held in Anchorage, Alaska's largest city and home
to half the state's population. In mid-October the average temperature
is 41 degrees F with approximately 11 hours 30 minutes of daylight. The
city is at 61 degrees N latitude on Cook Inlet, so come prepared
accordingly--it could snow.


The symposium will be held at the Regal Alaskan Hotel. The hotel offers
complimentary 24-hour transportation to and from Anchorage
International Airport as well as downtown Anchorage on a scheduled
basis, and complimentary parking for those with cars.

Guest room accommodations are being held for symposium participants at
a special rate. Be sure to make your reservations by September
25, 1995, and mention the crab symposium to obtain this special rate.

To register for the symposium contact the symposium coordinator by mail,
fax, or e-mail for additional information.

There is a modest registration fee that covers break refreshments; the
reception on Wednesday, October 11; symposium materials; and a copy of
the symposium proceedings. The registration fee is less if paid in
advance. You are urged to register and send in your fees in advance so
that adequate materials are available. If it becomes necessary to
cancel your registration, fees will be refunded at 75% if notice is
received by September 29, 1995.
