This year’s PFT was held in La Paz, Baja California
Sur, Mexico and hosted by the Center for Biological Investigation for Northwest
Mexico (CIBNOR). Dr. Fernando Garcia of
CIBNOR was PFT president and he was assisted by Patricia Hernandez (CIBNOR) as
treasurer and Ramon Pacheco of the Center for Investigations of Food and
Development (CIAD) in Hermosillo) as secretary. There were 87 in attendance representing Mexico, US, Canada,
Spain, and Germany. CIBNOR did an
excellent job in setting up the venue with the first day’s session at the
research institute itself and then followed by Tuesday and Wednesday’s sessions
at the Crowne Plaza Hotel. Besides
well-rounded program of presentations and posters some of the more memorable
features of this year’s PFT were: president’s reception with a backdrop of a
Baja sunset, fish (also shrimp, octopus, and oyster) tacos under the CIBNOR
palapa, the variety of Baja beaches, the Tuesday banquet with the folkloric
ballet of Mexico followed by dancing till midnight with music from the 50s to
90s. La Paz itself added to the festivities with their own version of Carnival
being held on the streets.
The sessions were divided into 5 categories
including processing, biochemistry, aquaculture, safety, fisheries and
education/training. The following is a
list of the presentations. If you are
interested in receiving more information about the paper, please contact the
author directly. There were five
student awards which were made available through donations from TELMEX and
Manuel Romo. The awardees were
Hermenegildo Olivas-Burrola of University of Sonora-Hermosillo, Jacek Jaczynski
of the Oregon State University Seafood Laboratory, Adriana Muhlia-Almazan of
CIBNOR, Julio Cordova-Murueta of CIBNOR, and Gabriela Sanchez-Brambila of
CIAD.

Tour of CIBNOR Facilities
- After a great lunch of fish tacos and cerveza
most of us joined in for a tour of CIBNOR’s facilities which were quite
extensive. There was a lot of interest
in their shrimp and mollusks aquaculture operations. The Centro de Investigaciones Biológicas del Noroeste (CIBNOR)
(in English: Northwest Biological Research Center) is a public institution of
the SEP-CONACyT system, with the mission of carrying out activities in
scientific research, technological innovation and human resource development at
the postgraduate level. Research is
oriented towards the solution of problems relating to the use and management of
natural resources to promote sustainable development, with priority toward the
northwestern region of Mexico. CIBNOR
is one of 27 centers of the Department of Education and the National Council of
Science and Technology of Mexico. It
offers unique opportunities for scientific research due to its location in the
southern part of the Baja Peninsula, in direct contact with the Sea of Cortés
and the Sonoran Desert. The Center has 119 researchers in the fields of
aquaculture, dry-lands agriculture, environmental protection, global change,
evaluation of natural resources, marine and terrestrial biotechnology and other
important facets of biology of the region and the world. More information can be found on their web

Baja
California Fisheries Workshop – Chairmen: Dr. Fernando Garcia, CIBNOR and Dr.
Ramon Pacheco (CIAD).
This was a 3-hour workshop for those interested in knowing
more about the state of Baja California fisheries and discussions of present
issues and problems. There were about
20 in attendance at the workshop, mostly all from the region, and they were
evenly divided between representatives from the fishing industry, local and
state agencies, and academia. Dr.
Garcia gave introductory remarks and commented that if Baja California is to
develop and improve its fisheries and explore new market opportunities then
both industry and institutions need to work closely together. This hasn’t happened very often in the past
as researchers have focused mostly on publications and not applications of
their research, and the industry has not been too forthcoming in terms
requesting help and showing a willingness to share expenses. Dr. Pacheco also stressed that it would be a
much more fruitful situation if industry would come to researchers and granting
agencies more often to identify their needs and work with researchers to
undertake some problem solving. Dr.
Morrissey observed that industry-researcher collaboration is more difficult in
Mexico and in many non-US countries because they do not have an extension
system that can bridge the gap between industry and university
researchers. There was general
agreement that a round-table discussion such as this is needed as a first step
in getting researchers and industry together at the table to discuss what
research is needed for both the long-term and the short-term. Some specific research needs were identified
which were specific to the industry representatives at the workshop and these
included: alternative market forms and improved quality for the giant squid
industry in the Sea of Cortez. Industry
would like to focus on domestic markets as the international markets are
saturated. However, domestic markets in
Mexico are difficult to open since there is little history of squid consumption
among most Mexicans. Another area was
the use of algae in aquaculture. New
technologies are needed or information about technologies for harvesting
macroalgas and using them for feed supplements in the growing aquaculture
industry. Another group was interested
in developing new markets for yellow-fin tuna.
Most of the yellow-fin currently goes into the can when there are
opportunities for other market forms.
However the quality and safety aspects of these products needs to
significantly improve for this to happen.
Help with quality and safety (i.e. HACCP) is available at several
institutes. Dr. Arturo Muhlia of CIBNOR
outlined several potential research opportunities and avenues to obtain funding
for applied research projects especially cooperative projects between
universities and industry. M.C.
Evangelina Guzmán from the Agency of Fisheries Development of Baja California
Sur, presented her work on collecting information related with the state of the
Baja California Fishery Industry in terms of both capture and processing.

Education and
Training. Chairman: Robert Price,
University of California, Davis
Panelists: Don Kramer, Univ. Alaska, Robert
Price, Univ. California-Davis, Michael Morrissey, Oregon State Univ., Chuck
Crapo, Univ. Alaska – Kodiak, Jae Park, Oregon State Univ. Seafood Lab.
This
was a round table discussion of different panelists brought together by Ken
Hildebrand of Oregon Sea Grant. Ken
opened the session by reviewing the concepts of extension and its development
in land-grant colleges throughout the US over the past 100 years and more
recently Sea Grant extension. He stated
that over the next five years there will be changes in Sea Grant extension
brought about, in part, by several retirements that would occur in Oregon and
California. This will also present new
opportunities and he called on the panelists to give an overview of extension
in their area and what they see the future will be. Don Kramer from Alaska started things off by reviewing a series
of short-courses that Alaska extension has developed for the seafood
industry. These have been successful
and he sees Alaska extension continuing to hold courses and be heavily involved
in training. Michael Morrissey of
Oregon saw extension being more involved in research that it has been in the
past. He noted that traditionally
processors/fishermen would use extension agents to be a liaison between the
industry and the researchers. Now
industry is going directly to the researchers themselves to get information,
which should mean that the new extension agent should be a part-time researcher
himself. Morrissey also stated that he
would like to see the new position in Oregon be more involved with consumer
education and be a liaison between the industry and the consumer who is often
getting mixed messages about fisheries.
Bob Price from California agreed that more extension positions carry a
research component, but he also feels that is the transfer of information, in a
general sense, is a key role for Sea Grant extension agents. He cited the Seafood NIC (http://seafood.ucdavis.edu) web page as
an example as a web site that facilitates this information transfer. Chuck Crapo from Alaska said that he was in
agreement with pretty much what has been said and that industry involvement is
key to successful outreach programs.
Jae Park, although not having an official extension position, is
involved in training through his Surimi School which focuses on training middle
management on surimi and surimi Seafood now-how and methods. He said that he will be adding a Surimi
forum to his Surimi School this year that will gear more to upper management to
bring them up-to-date with new ideas and directions. Ken opened it up to the audience and Denise DeLeebeeck from B.C.
Institute of Technology stated that there is a great need for more training in
the BC industry but there are few people available to run the programs. She reviewed what was going on at present. Liz Brown from Sheldon Jackson College in Sitka reviewed their short-course
training programs that are partially funded through industry. Both Ramon Pacheco from CIAD and Fernando
Garcia and Arturo Muhlia from CIBNOR stated the lack of good extension programs
through universities or research institutes in Mexico and the need to begin
these programs. They cited the Baja
Fisheries workshop, which was held on Tuesday as a good first step. Ken Hilderbrand noted that the last 25 years
there has been a good working relationship between the West Coast industry and
extension because there were people in the industry that knew seafood
technology and the value of research.
Many of these people from industry are retiring as well and it will be
interesting to see who steps to the plate.
Ken thanked everyone for his or her participation.

Business Meeting – The PFT group thank
Fernando and his organizing committee for the great job they did in hosting
PFT. They also liked the PFT logo
developed by CIBNOR so much that a vote was taken and the logo has been adopted
as the official PFT logo. George Pigott
had two copies of a very thick volume that represented PFT history from 1948
on. This will be edited and then will
be available to PFTers who are interested.
It was also noted that the first official meeting of PFT was in
1950. Joe McGrath was elected PFT
president for the year 2001-02 and Norman Haard will be the PFT Program
Chairman. The 53rd PFT will
be held in Reno, Nevada, February 24-27, 2002.
