The Hawaii Aquaculture Association is the statewide
producers’ organization. Its mission is to foster the de-
velopment of commercial aquaculture production in
Hawaii. HAA provides a unified industry voice for leg-
islative issues, opportunities for networking and fellow-
ship with other aquaculturists, and numerous other
benefits to members.

                       HAA Annual Meeting - November 8 at Waikiki Aquarium
The HAA 2008 General Membership Meeting will be held at the Waikiki Aquarium on Saturday evening, November 8, 2008.
This will be a family event and will include an opportunity to tour aquarium exhibits, talk story, and enjoy a spectacular sunset,
beer, wine, buffet dinner catered by Indigo Restaurant, special program, and annual business meeting. Hope to see you there.

                                       President’s Message
Aloha Fellow Aquaculturists,
    I am writing to ask each of you to please consider committing a few hours or more of your time each year to help support the
efforts and activities of the Hawaii Aquaculture Association (HAA).
    Over the past dozen or so years, the HAA has gained recognition in Hawaii, nationally and internationally, as the organization
representing our Hawaii aquaculture industry.
    HAA’s accomplishments include: organizing annual conferences and membership meetings, organizing and co-sponsoring
numerous workshops, seminars, and industry meetings, hosting and supporting the World Aquaculture Society’s 2004 meeting
in Honolulu, initiating aquaculture legislation, representing our industry’s needs and positions each year at the Hawaii Legisla-
ture, dialoguing with various Hawaii State government agencies and legislators, national agencies, and our congressional delega-
tion, participating in a variety of national aquaculture forums, and, when appropriate, joining forces with the Hawaii Farm Bu-
reau Federation, the Hawaii Science and Technology Council, the National Aquaculture Association, and the American Farm
Bureau Federation to promote the needs and positions of our industry. The vast majority of this work has been accomplished to
date by dedicated members of the HAA Board of Directors and a few non-board members who together represent less than ten
percent of our association’s total membership. This dedicated core group is, however, getting increasingly exhausted, and is
encountering other pressing commitments. In short, HAA is in dire need of active assistance from additional members to help
keep our association viable and dynamic.
    It has been my observation that many, if not most, successful local and national trade and professional organizations that have
been successful and viable over the long-term have been so because employees of large companies or the owners of financially
successful small- or medium-sized companies have had the resources to commit considerable time and energies to these organi-
zations, or, that the organizations have been large enough and/or have sufficient dues or other revenue generating structures that
allow them to hire part- or full-time staff. However, in the HAA’s case, the bulk of the workload has been carried out by the
owners of a few small “mom-and-pop” operations or small businesses still striving to reach financial success, and a few commit-
ted government employees, all of whom add their HAA time commitments to their already overloaded schedules, because they
are committed to the larger success of our industry and because our dues have been insufficient to allow our organization to op-
erate otherwise.
   I have periodically mentioned this situation in passing over the years but feel we have reached the point where I no longer
                                                                                                              (Continued on page 8)

Board Member’s Message
                            The Chinese are Coming, the Chinese are Coming!
Two recent articles in the local newspaper have prompted me to share a few thoughts on markets and marketing. One article
dealt with a California fish farm, the Fishery, owned by Ken Beers, a pioneer in the California industry, and the other article dis-
cussed the new trend in tourists from the Peoples Republic of China (PRC).

A few quotes from an article on July 18 in the New York Times (link no longer working): “Catfish farmers across the South, un-
able to cope with the soaring cost of corn and soybean feed, are draining their ponds.” “.. corn and soybeans have nearly tripled
in price in the last two years, .. harvest shortfalls, increasing demand by the Asian middle class, government mandates for corn to
produce ethanol and .. flooding in the Midwest.” “Feed is now more than half the total cost of raising catfish, compared with a
third of the cost of beef and pork .. .” “ ‘It’s a dead business,’ said John Dillard, who pioneered the commercial farming of cat-
fish in the late 1960s. .. As for his 55 employees? ’Those jobs are gone.’ “ “Some catfish producers recently switched to a feed
based on gluten, a cheaper derivative of corn, .. but .. transportation and prices were particularly hard hit by the Midwest floods.”
“ ‘The industry is going to implode,’ (said the president of a processing company, blaming the government’s mandates making
fuel compete with food for the corn harvest).’ “ “ ’I’m a farmer (said another interviewee). I’m used to peaks and valleys. But
this is like falling into the Grand Canyon.’ “
    Somber thanks to Jim Steeby of Mississippi State U. for this reference, and discussion of the matter.
    A late pertinent note: University of Hawaii researchers are developing technology to convert what is now a waste product
from sugar cane ethanol production into a substitute for imported fishmeal. UH-Manoa scientist Samir Khanal said his team is
looking at converting residue called vinasse from sugar cane ethanol production on Maui and Kauai. (They noted that other) re-
searchers grew a fungus in fermentation leftovers from corn-produced ethanol. They said it saved energy, recycled more water
and improved livestock feed.

Letting the Sea Cultivate the Land
From the Los Angeles Times of July 10: “A few miles inland from the Sea of
Cortez, amid cracked earth and mesquite and sun-bleached cactus, neat rows of
emerald plants are sprouting from the desert floor. The crop is salicornia. It is
nourished by seawater flowing from a man-made canal. And if you believe the
American who is farming it, this incongruous swath of green has the potential
to feed the world, fuel our vehicles and slow global warming. He is Carl
Hodges, the founding director of the University of Arizona's highly regarded
Environmental Research Lab.

The topics of this year’s workshop ranged from yellowfin tuna
broodstock capture, broodstock maintenance, spawning, and
larval rearing. Additionally, the program covered culture tech-
niques for other pelagics such as cobia and Seriola. This arti-
cle provides an overview of that information.
    Broodstock capture is an important first step of any aqua-
culture operation. Pelagic fish prove to be a difficult group to
capture and transport due to their unique physiology and biol-
ogy. During the workshop, IATTC demonstrated proper han-
dling techniques applicable to tuna species without the use of
anesthesia. They are able to catch the tuna approximately two
miles offshore and ensure less than one hour time from capture
to holding tank with minimal handling. Another key to their
success is the year round availability of a variety of pelagic
species such as yellowfin tuna, skipjacks, black skipjacks,
wahoo, billfish and mackerels.

                                                                      Developmental stages of yellowfin tuna. Clockwise from top left –

leader of the Aquaculture Development Program. He is eager to take on issues as varied as               Phone: 808 587-0030

budget control, legislative bills, and long and short term strategic planning to keep Hawaii’s
aquaculture industry healthy and competitive. His career has uniquely prepared him for these            Email: info@hawaii-
    Immediately upon completing his MBA at the University of Hawaii, Todd was sent by Prince            Web: www.hawaii-
Hotels to assist with the opening of the Hapuna Beach Prince Hotel on the Big Island. He di-
rected the procurement and installation of the FF&E (furniture, fixtures & equipment) and pro-
ceeded to turn an empty building shell into one of the world’s premier resorts. Subsequent pro-
jects included renovating the Mauna Kea Beach Hotel, Maui Prince Hotel and the Hawaii Prince
Hotel. Along the way he gained experience in supervising teams of contractors as well as his
own staff, and learned a few things about keeping a complex project on schedule and on budget.
    He later joined the Hawaii Visitors & Convention Bureau (HVCB) where he was responsible
for interactive marketing programs to Asia, Australia, Europe and North America. While there,
he worked to develop the state’s official tourism web site (, which is still in
place and thriving today. He also oversaw the distribution of 250,000 emails per month to pro-
spective visitors. At HVCB he gained a heightened appreciation for the importance of clear,
direct communication.
    A stint as the Product Development Manager for American Savings Bank provided experi-
ence in legal matters and project management, and his MBA came in handy when he was called
upon to do financial modeling in preparation for launching new products. He also oversaw
training modules prior to the roll-out of those products.
    Todd is coming to ADP from the Hawaii Department of Agricul-
ture (HDOA) Market Development Branch where he managed the
following programs:
          Seals of Quality: This program helps companies market
their premium products locally, and is helping them break into the
Japan market.
          Buy Fresh Buy Local: This campaign utilizes various me-
dia to encourage Hawaii consumers to purchase local food products.
Better taste and freshness is emphasized, and the fact that “buying
local” strengthens our local communities and economy. He continues
to serve on the BFBL Steering Committee and plans to feature aqua-
culture products in the future, as well as profiling aquaculture farmers,
products, and displaying seafood recipes.
          Matching Marketing Funds Program: This program sup-
ports associations in marketing with distribution, tradeshow and
                                                                          Todd Low with Hawaii Aquaculture Association President
education projects.                            (Continued on page 6)        Ron Weidenbach at the 2008 Agriculture Conference.

   A daily part of the workshop included presentations and discussions
led by Dan Bennetti (University of Miami) and IATTC researchers cover-
ing a wide range of concerns and future research ideas, advanced hatchery
techniques and open ocean operations. There were also many helpful
hints exchanged like the use of cleaner wrasses to control parasites in
cobia production and wearing jeweler’s glasses while performing surgery.
Each participant gave a presentation on the aquaculture work they have
been doing related to tuna, Seriola, and cobia. We presented our plans for
bigeye tuna culture in Hawaii.
   At our PACRC Keaukaha site in Hilo, we are currently renovating one
of the 1900 ton tanks in collaboration with Paul Troy of Hawaii Oceanic
Technology and other partners. Preliminary research focused on the feasi-
bility of capture and transport of bigeye tuna is underway and we hope to
start collecting tuna broodstock this December. We are also drawing up
plans for the hatchery and looking into potential grow out options.

   A benefit of having come through the HDOA Market Development Branch is that he knows agricultural distribution systems,
and knows how to get products to market. Needless to say, all this experience will be invaluable to Hawaii’s aquaculture com-
    How’s this for a refreshing approach to marketing: “I don’t see marketing as selling” he says. “It is communication. It is
education. ADP will focus on getting our message out. We will be communicating with the public, with the legislature, with the
farmers, and with HDOA.”
    During his acclimation period at ADP Mr. Low will have excellent technical resources to draw upon. “The combined knowl-
edge and experience of Aquaculture Specialist Dr. Leonard Young and Aquaculture Veterinarian Dr. Allen Riggs is incredible”
he says. “Our team is very strong.”
    Todd is upbeat in his assessment of the future for ADP. “The aquaculture community owes a debt of gratitude to Leonard
Young who, in addition to his regular duties, took on the role of Acting Director for two years. He stepped up and took the reins
when it was needed. He did a great job, and is turning over the program in good shape and ready to move forward.” Dr. Young
is happily returning to full-time research, developing protocols, testing, and handling the more technical aspects of aquaculture,
and he will be Todd’s greatest asset as he learns more about the peculiarities of the industry.
    Todd Low joins ADP as a manager who has great energy and enthusiasm and is open to everything. He will talk to anybody,
will entertain new ideas, and is willing to try things that are different. “It’s an exciting time to be involved in aquaculture in Ha-
waii.” Indeed. The road ahead will be exciting, and challenging. And Todd Low loves a challenge.

(HAA Board Member’s Message, from page 2)
    The Fishery and several other Cal-based farms are taking advantage of strong demand for live product in the growing ur-
ban/suburban ethnic markets in San Francisco, Oakland, San Jose, Sacramento and Los Angeles. Live haul trucks daily deliver
wriggling sturgeon, largemouth bass, catfish, tilapia, and carp to enthusiastic Asian market and restaurant owners, with customers
waiting in line. According to the article, the Asian appetite comprises 70% of California's $50 million dollar aquaculture industry
and customers are begging for more product. Unfortunately, shipping live fish from Hawaii is not an option, but is there a value-
added product?
    Ethic markets craving live fish is old news for Hawaii's fish farmers, but new news may alter our view somewhat. Recent
simplification of visa procedures, coupled with the booming market-based economy of the PRC, has created a new phenomenon,
the Chinese tourist coming to explore the U.S. Visitor numbers to Hawaii alone are expected to rise dramatically in the next few
years from a few thousand to 135,000 by 2009. Currently, the Chinese tourists stay longer and spend more money than the Japa-
nese tourist.
    This emerging trend begs the question, what are these folks going to want to eat and where are they going to eat it? Will it be
Sam Choy's or Roy's or will it be Hee Hing's and the many restaurants in Chinatown? The bet is these folks will look for familiar
dishes, at least during a portion of their stay. Hawaii's large and small Mom and Pop fish farms have an opportunity to supply
this new demand.
    But if farmers can supply the fish, what kinds of information would help farmers sell product? I think it would be helpful if
we find out what these visitors' eating habits will be (fish or steak?). What are they looking for in terms of species? What types
of eating establishments will be favored? That is, some good old-fashioned market research by UH or the State. In addition, pro-
motional brochures or posters catering to these visitors could be another action.
    No doubt Hawaii's experienced farmers will have other ideas on how to address the Chinese influx. But the point is let's rec-
ognize it is as new industry opportunity and actively work together to take advantage of the emerging demand.

                 Atlas of Hawaiian Watersheds & Their Aquatic Resources
When your editor took up his extension specialist job on the Big Island some years ago, he tried to identify issues and types of
information that folks would like to know more about. One suggestion was to find an information resource about local streams
as water sources for aquaculture. We quickly found a USGS web site that had some useful information. It was not particularly
user-friendly, but it has been the best we knew about until now.
    A joint effort between the Hawaii Division of Aquatic Resources and the Bishop Museum has produced this comprehensive
atlas, available free at It is a large and comprehensive resource, addressing 430 watersheds,
including physical, geological, and biological characteristics of the areas, and, yes, data on water flow as well.
    Thanks to Sharon Ziegler-Chong of PACRC for passing on this item.

Notice to the Community from ADP
Pacific white shrimp (Litopenaeus vannamei) postlarvae are now available from Paradise Shrimp Farms in Waialua. On August
12, 2008, representative postlarvae samples tested negative by PCR methodology for IHHNV, WSSV, TSV, YHV, BP, MBV
and IMNV, completing the certification process.
   Paradise Shrimp Farms is an SPF (Specific Pathogen Free) marine shrimp broodstock, and now seedstock, production facility
on Oahu, whose proprietor is Mr. Jung Hoi Ku. The farm is located at 67-021 Waialua Beach Rd. Waialua, HI 96791; telephone
808 389-1163.
   As a reminder: First, a site inspection is required for all Hawaii aquaculturists before acquiring postlarvae and commencing
production operations. Please contact the Plant Quarantine (PQ) Invertebrate & Aquatic Biota Specialist, Mr. Vernon Nakamoto,
at 832-0577 to arrange this inspection. Second, an Intra-state Live Movement Permit from PQ is also required prior to pur-
chasing and transfer of any postlarvae from any approved supplier in Hawaii. This permit must be shown to the supplier before
transfer, as both supplier and purchaser can be held responsible for unauthorized live seedstock transfer. For more information,
contact Mr. Nakamoto, or the State of Hawaii Aquaculture Veterinary Medical Officer, Dr. Allen C. Riggs, at 832-5005.

 have the luxury of being subtle. The dedicated HAA core needs your help now to plan and put on our next annual meeting, our
 next conference, and our co-sponsored workshops, to participate in the October 12, 2008 Hawaii Fishing & Seafood Festival, to
 continue the ongoing strategic planning process to help guide our industry’s future, to prepare for and participate in the next
 legislative session, and to respond to other industry issues as they arise. For the Board’s part, we will try to rework the way we
 do business to make it easier for more members to be involved. On your part, when we present opportunities for you to be
 more involved, please respond positively. In addition, please check with your island’s Board representative(s) to offer sugges-
 tions and to volunteer whatever time and effort you can spare. The Hawaii aquaculture industry will benefit and your help will
 be greatly appreciated by all members and, in particular, by the current active core.
Best wishes, Ron Weidenbach, HAA President

CORRECTION 1: In the last issue, a note on bluefin tuna stated that its documented growth rate to 20 kg in two years exceeded
that known for mahimahi. Thanks to Syd Kraul for pointing out that mahi can and have beaten that rate, e.g. 20 kg in 1.5 years.
Your editor (who wrote the note) regrets the error and encourages readers to continue to help us get things right.

CORRECTION 2: Also in the last issue, a note the Nile tilapia stated that it was now “conditionally approved for research and
exhibition.” Thanks to Domingo Cravalho for pointing out that the correct designation is “restricted for research by government
agencies and universities only.”

(Salicornia, from page 3)
    A so-called halophyte, or salt-loving plant, the briny succulent thrives in hellish heat and pitiful soil on little more than a regu-
lar dousing of ocean water. Several countries are experimenting with salicornia .. as sources of food. Known in some restaurants
as sea asparagus, salicornia can be eaten fresh or steamed, squeezed into cooking oil or ground into high-protein meal. .. It can
be converted into biofuel. And, unlike grain-based ethanol, it doesn't need rain or prime farmland, and it doesn't distort global
food markets.”
    On line:
    Thanks to Taira Yoshimura for the reference.
    [Editor’s Note: Salicornia is also known as “pickleweed,” but for some reason (perhaps the same reason that some producers
of “seaweed” have sought alternative names), the article doesn’t say that. Hodges’ successors at the U. of Arizona and others
have done considerable research on halophytes and other dry climate crops. Their Biosphere 2, where more of this is explained,
was still a great stop as of a few years ago.]
