High Health Aquaculture Golden and Red-Striped Shrimp
On January 10, 2008, I interviewed Dr. Jim Wyban, president of High Health Aquaculture (HHA) in Hawaii, a USA-based facility that produces specific pathogen free (SPF), fast-growing, virus-resistant, genetically improved shrimp broodstock.
Shrimp News: Hi Jim, what’s the current status of High Health Aquaculture?
Shrimp News: What are you doing with your P. monodon broodstock?
Shrimp News: Are you still working with P. japonicus broodstock?
Jim Wyban: No, we worked with japonicus
Shrimp News: What about stylirostris?
Jim Wyban: Yes, we’re still working with stylies. We’re collaborating with the IFREMER Group in New Caledonia on some very interesting breeding experiments with stylies. Hybrids from our SPF stylirostris and the New Caledonia stock of stylirostris outperformed both of the parent stocks by a considerable amount in both growth and survival. IFREMER did crosses in both directions, our males with their females and our females with their males, and in both cases, the hybrids outperformed the parent stock. In 2008, some shrimp farms in New Caledonia will stock the hybrids. This was no small research artifact. These were significant results from a controlled study. In 2008, a paper will be published on this research in the journal Aquaculture, along with the production data.
Shrimp News: In 2005, High Health Aquaculture formed a joint venture with Thai Union Feed Mill to produce specific pathogen free, fast-growing, Taura-virus-resistant vannamei nauplii and postlarvae in Thailand. Through the grapevine, I heard that the joint venture had ended. Is that true and what can you tell me about it?
Jim Wyban: Yes, that’s true. We were partners in developing a $10-million hatchery called “High Health Thailand”, which was completed in 2006 at a 37-acre site north of Phuket. We purchased the site, designed and built the hatchery, supplied broodstock, hired, organized and trained the technicians and then ran into some differences with our partners. We just could not come to terms on how to manage certain aspects of the business. The Thais wanted to take the company in one direction and we were determined to take it in another. We eventually negotiated a settlement, and Thai Union bought out our shares in the hatchery. We parted in good company and still communicate on a regular basis. It’s now called Thai Union Hatchery. As part of the settlement, it’s no longer called High Health Thailand. All and all, it was a good experience for me; I love Thailand, which remains a great market for our products.
I would like to add that the concept for the HHT hatchery—combining the best broodstock in the world with the best hatchery practices in the world—resulted in the production of an exceptionally robust PL that’s generally not available elsewhere in the industry. Most hatchery owners are least cost operators. Even if they use expensive, imported, SPF broodstock, they still produce postlarvae as cheaply as possible. For example, we’ve learned over the years that the more Artemia you feed in the hatchery, the better performance you get during growout. In Thailand, the average hatchery uses less than a kilogram of Artemia cysts to produce a million postlarvae. If you feed the postlarvae all the Artemia they want, however, they’ll consume ten times as much. That’s what we did at HHT. As a consequence, we produced a huge PL-10. You get very rapid growth—and it doesn’t increase total costs that much. Hatchery owners want to cut costs, so they feed less Artemia and wind up with less than a perfect PL. Farmers who used our PLs reported exceptionally fast growth (over 0.2 grams per day). Our concept at HHT worked. Now, we’re talking with other groups that might want to develop similar projects.
Shrimp farmers need to lower their costs. They need to produce shrimp for less than three dollars a kilo. In my experience, the best way to cut costs is to improve PL quality. Although this might raise hatchery costs, the increased growth and survival during growout will more than compensate for the higher hatchery costs.
Shrimp News: What else are you up to?
Jim Wyban: In our research and development program, we’re looking at the genetics of shell color and shell patterns. In our vannamei breeding program, we discovered that one out of a 100,000 animals was a beautiful golden yellow, the color of a ripe banana, but even more golden. They really stand out. For a couple of generations now, we’ve been trying to concentrate the genes responsible for the gold color, with the idea of producing a golden vannamei stock, which could then be branded. The color persists even when you ice the animals down.
Wyban has posted videos of his Christmas shrimp celebration and a broodstock harvest to YouTube. You can view them at http://www.youtube.com/watch?v=4HNitYhscsI. On the six-minute Christmas video, Wyban says:
“Welcome to Kona, Hawaii. We’re broadcasting on the shrimp network. This is the annual event of the year, the High Health Annual Christmas Party, and the feature is eating shrimp. We’ve cooked broodstock-sized shrimp in four different recipes and we’re going to focus on how good these shrimp have been to us and how good they are to eat. This is for all of our friends around the world. Merry Christmas and Happy New Year.”
While discussing one of the dishes in the video, Wyban says: “One of the things that’s really important about these shrimp...is their red color. Look at how beautifully orange/red these animals are. This result is the combination of our culture system, good nutrition and our secret method of processing. ...That combination results in these beautiful red shrimp, a color that’s very important in Japan.”

Mangroves Are Important But Some Shrimp Farms Are Okay
Mangroves in coastal Thailand are the main protection against deadly flooding from tsunamis, so it seems wise to protect them at all costs. Removing some mangroves, however, and replacing them with shrimp farms doesn’t necessarily reduce the mangroves’ power to blunt tsunamis. In that observation lies a fresh, quantitative approach to how policy makers can protect the environment and allow growth and development that improve local residents’ lives.
Governments and managers worldwide are leaning toward a system known as “ecosystem-based management” to achieve their environmental goals. Under ecosystem-based management, policy makers include man and his activities in the environmental equation.
In this study, from a recent issue of the journal Science, researchers assigned dollar values to the mangroves’ protective powers and then compared those values to the dollars earned from shrimp farming. Their conclusion: Small losses of between 10 and 20 percent of mangroves—where massive expanses of mangroves already exist—are outweighed by the gains from shrimp farming.
In other words, as long as farmers don’t destroy too many mangroves, they can still build shrimp ponds and make money—and the remaining mangroves will still protect the shoreline from tsunami storm surges.
The research was funded by the National Center of Ecological Analysis and Synthesis and the Packard Foundation. Researchers from 14 universities and institutes around the world contributed to the Science report.
Excerpts from the Science Report
“To explore this possibility, we applied these nonlinear wave attenuation relationships for coastal systems to a case study from Thailand where choices have been made between conversion of mangroves to shrimp aquaculture versus their preservation for key ecosystem services (such as coastal protection and fish habitat). Our case study assumes a mangrove habitat that extends 1,000 meters inland from the seaward edge along ten kilometers of coast. Nearby communities depend on the mangrove for forest and fishery products.... Coastal communities up to five kilometers inland are protected from tropical storms by mangroves. The alternative to preserving mangroves is converting them to intensive shrimp ponds, which overwhelmingly benefits outside investors.”
“The storm protection service of mangroves still dominates all values, but small losses in mangroves will not cause the economic benefits of storm buffering by mangroves to fall precipitously. The consequence is that the aggregate value across all uses of the mangroves (i.e., shrimp farming and ecosystem values) is at its highest ($17.5 million) when up to two square kilometers of mangroves are allowed to be converted to shrimp aquaculture and the remainder of the ecosystem is preserved. This outcome also yields a more equitable distribution across stakeholders, which may be an important objective in any ecosystem-based management strategy for coastal management. Local mangrove-dependent coastal communities and other coastal communities living within five kilometers inland would obtain approximately the same share of economic benefits from the mangrove system ($15.6 and $13.2 million, respectively), but now outside investors would earn some commercial profits from shrimp farming ($1.9 million). Finally, we note that the outcome from our Thailand mangrove valuation example corresponds to ‘best practice’ guidelines for mangrove management in Asia, which recommend that ideal mangrove/pond ratios should not exceed 20% of the habitat area converted to ponds.”
“By including nonlinear relationships in an economic valuation of ecosystem services, our results challenge the assumption that the competing demands of coastal interface systems must always result in either conservation or habitat destruction.”

Country Reports
Bangladesh 420,000 Harvest Wild Postlarvae
About 420,000 people are involved in shrimp postlarvae collection along the estuaries and coastline of the Bay of Bengal in Bangladesh. Collection from wild sources has a reputation for being ecologically destructive because of all of the other species captured and destroyed in the process. In 2000, the government imposed a ban on postlarvae collection to protect the fisheries. But the collectors don’t pay much attention to the ban, knowing that the government won’t enforce it because a ban would displace nearly a half million people.
Who are the fry collectors? To get socioeconomic information on them, 72-85 collectors were interviewed weekly from three harvesting sites. This paper analyzes the larvae collection and distribution efficiency, livelihood strategy of fry collectors, user options for fisheries management and the roles of various stakeholders. Results show that poverty, migration, credit systems and lack of coordination of service-providing agencies all have important influence on shrimp fry collection in the coastal zone.

Belize World Wildlife Fund Meeting on Shrimp Farming Standards
Jose Villalon, Director, Aquaculture Program, WWF-United States; and Sylvia Marin, Regional Representative, WWF-Central America, report:
“On behalf of the World Wildlife Fund’s Central America and United States offices, we are writing to invite you to a meeting in Belize April 1st and 2nd to begin developing standards for certifying responsible shrimp farming in Central America/Mexico. We hope you will play a role in creating the first set of measurable, performance-based shrimp farming standards that are created by consensus.
As a key stakeholder in the shrimp aquaculture industry, your input at the meeting is invaluable. We are encouraging an open dialogue with the shrimp industry’s leading producers, processors and retailers, as well as representatives from academia, governmental agencies and nongovernmental agencies.
This will be the first meeting of the Shrimp Aquaculture Dialogue in Central America/Mexico. Over the course of the year, we will identify criteria to focus on in order to reduce each of the key environmental and social impacts related to shrimp farming. We then will create indicators, or points of measurement to determine the extent of each impact. The final step will be developing standards that are quantitative performance levels to evaluate whether a principle is being achieved. The standards will be based on the “International Principles for Shrimp Farming”—high-level goals for shrimp farming—adopted in 2006 by the Food and Agriculture Organization of the United Nations (FAO).
Two or three additional meetings will be held in the region over the next year to continue the discussion. Similar meetings will be held to develop standards for East Africa and Asia. These three sets of standards will be harmonized into one global set of standards.
The Shrimp Aquaculture Dialogue in Central America/Mexico is one of five WWF-initiated Dialogues underway globally. Standards also are being developed for salmon, tilapia, pangasius and molluscs. Dialogues for seaweed, trout and abalone will begin later this year.
The first shrimp Dialogue in your region will be from 9 a.m. to 5 p.m. April 1st and 2nd at the Radisson Fort George Hotel & Marina in Belize City. Registration will begin at 8:30 a.m. on April 1st. The main goals of the meeting will be to begin creating criteria, elect a steering committee and discuss a process for moving forward.
If you are interested in attending, please contact WWF shrimp dialogue coordinators Eric Bernard (phone 33-(6)-98-40-53-93, email eric.bernard-ac@wanadoo.fr); or Mauricio Mejia (phone 501-223-7680, email mmejia@wwfca.org) by March 15, 2008.
We encourage you to make hotel reservations as soon as possible by contacting the Radisson, or another hotel in the area. For information about the Radisson, go to www.radisson.com/belizecitybz.

Canada Greenpeace
The global aquaculture industry is not a solution to overfishing and must dramatically change in order to become sustainable says a new Greenpeace report titled “Challenging the Aquaculture Industry on Sustainability”. Presented at the 2008 Seafood Summit in Barcelona, Spain, on January 28, 2008, the report documents how fish and shrimp farming are damaging marine and freshwater ecosystems by destroying coasts to make way for ponds, by polluting water with fecal waste and by capturing wild animals for feed and farm stock.
Human rights abuses, which are often forgotten in the aquaculture debate, plague shrimp farming. In Bangladesh, about 150 murders linked to aquaculture have been reported. The report also highlights the devastating impacts of aquaculture effluents on the ecosystem.
To address these problems, the report offers specific recommendations for the industry to move towards sustainability and calls on retailers to buy only from sustainable aquaculture operations.

The Gambia (West Africa) Pirang Shrimp Farm Closed to Birders
From a blogging birder: Just back from a two week trip to The Gambia and thought it would be useful to inform anyone planning to visit the Pirang Shrimp Farm that it’s closed to birders and the public.
On the day we visited, a couple of well-known bird guides were present and they failed to convince (i.e., bribe) the workers to let us in. The workers said they would be sacked if they let us birders in.
Apparently, this is due to the Swedish owners of the shrimp farm not being happy that their workers are being distracted by birders, so they’ve closed it forthwith.

Japanese seafood supplier Maruha Group, Inc., will purchase 100% of Agrobest (Malaysia), Sdn., Bhd., a Penaeus monodon shrimp farming operation, for approximately $30 million. In 2006, Agrobest exported nearly all 2,600 tons of its production to Japan. Agrobest plans to produce 7,500 tons of shrimp in 2009, more than half of it the western white shrimp, P. vannamei! Information: Thompson Financial (yasuhiko.seki@thomson.com).
The Maruha Group is the second major Japanese trading company to invest in shrimp farming recently. In April 2007, Mitsui & Co. acquired 37% of Allied Pacific, a Hong Kong-based firm engaging in shrimp farming and shrimp processing in China.

Mariana Islands Selling Broodstock to Indonesia
In December 27, 2007, Saipan Aquaculture, a small shrimp farm in the Mariana Islands, exported 250, 10-month-old, Penaeus vannamei broodstock to one of the biggest shrimp hatcheries in Indonesia for $25 each, or $6,250, with the buyer paying the packing and shipping costs.
Saipan operations manager Rommel Catalma said there are stringent requirements on the export of broodstock. First, a farm or facility needs a two-year disease free certification from the University of Arizona and then it must pass an inspection by the department of fisheries of the importing country.
Saipan Aquaculture produces around 3,000 pounds of shrimp a month for local markets, like hotels and restaurants. The company employs two aquaculturists, a chemist, a sales and delivery person and two aquaculture aides.
Catalma says, “We’re looking at selling chilled shrimp in Japan, Korea, Guam and even Hawaii. Japan is the second biggest importer of shrimp in the world and it’s only three hours away.”
Catalma envisions selling broodstock to shrimp farmers in Indonesia, the Philippines, Vietnam, Malaysia, Thailand and China.

Thai shrimp exports to the USA are likely to shrink in 2008 because of the weak USA economy, so exporters seek new opportunities in Japan and Europe.
The United States accounted for 61% of the 300,000 tons of shrimp Thailand exported in 2006, but that share could fall to 48-49% in 2008, according to Niwat Sutemechaikul, deputy director-general of the Fisheries Department.
Stagnant sales this year could limit Thai shrimp output to 440,000 tons, about the same volume as in 2007 and far below the 530,000 tons produced two years ago, said Niwat, also known as “Mr. Shrimp” because he was appointed by the Thaksin Shinawatra government to oversee a cluster program intended to strengthen the shrimp industry. He said export revenue would fall if the baht continued to appreciate against the USA dollar.
Shipments to Japan rose 7% to 54,710 tons in the first 11 months of 2007. “The JTEPA (Japan-Thailand Economic Partnership Agreement) helped accelerate sales to Japan,” Niwat said.
In the first 11 months of 2007, exports to the European Union showed robust growth, up 54% in volume to 28,287 tons and 48% in value to $223 million. The performance was helped by the restoration of lower tariffs under the Generalized System of Preferences for developing economies.
Processors have been encouraged to export more value-added products and to offer shrimp in popular dishes. The target for 2008 is to increase the proportion of processed shrimp from 50% to 65%.
Kasikorn Research Center analyst Phakkaorn Dhipayathanadecha agrees with the suggestion that producers focus more on the export of prepared shrimp, rather than commodity products, to avoid competition from countries like Ecuador and Brazil. “They should highlight popular Thai dishes that use shrimp as a main ingredient such as pad Thai Kung and Tom Yum Kung,” she said.

Thailand Aquatic Biolabs
Philippe Tacon, working as a consultant for Aquatic Biolabs, reports:
ABL has its offices in Bangkok, and test facilities (ponds, wet lab) will soon be opened in southern Thailand. ABL can work at the customer’s site or subcontract work at commercial farms.
The managers and directors in charge of the company have vast experience in shrimp and aquatic animal farming dating back to the mid-1990s in Thailand, mostly in hatcheries and broodstock facilities for giant tiger shrimp and in R&D departments of aquafeed companies. Over the last four years, they have built a network of farm managers in Thailand.

Thailand Cooperatives
Ten years ago, the booming shrimp farming business attracted millions and millions of dollars from investors, many of whom went broke or incurred huge debts, leaving financial institutions with massive nonperforming loans on their hands.
Now, Pinyo Kiatipinyo, chairman of the Federation of Shrimp Farmers Cooperatives of Thailand, says the best way to structure the shrimp farming business is to group farmers together in cooperatives.
Pinyo said cooperatives could enforce good aquaculture standards and help shrimp farmers expand their markets both locally and overseas. He said Harnet Cooperative Company, a Japanese purchaser of Thai shrimp, planned to buy shrimp directly from Thai cooperatives; and Marks and Spencer, a United Kingdom-based retailer, has informed the Thai Fishery Department that it wants to buy shrimp from the farmers’ cooperative at Sam Roi Yod, Prachuap Khiri Khan.
In a bid to reduce shrimp feed costs, Pinyo said farmers have developed feeds made from local materials.

United States Hawaii—Oceanic Institute, Inbreeding Depression
This analysis encompasses survival, growth and disease challenge-test data on approximately eight generations of Penaeus vannamei. Within this pedigreed broodstock inbreeding coefficients vary among families, from a low of 0.0 (most families) to a high of 0.25. Both growth and survival of noninbred families were high during this period. Inbreeding had a small (but significant) depressive effect on growth and no significant effect on survival.
The effects of inbreeding on survival after challenge tests with viral pathogens was more noticeable and became particularly strong in severe (WSSV) challenge tests, where survival even of the noninbred families was considerably reduced. The effect of inbreeding on survival ranged from an 8.3% reduction per 10% inbreeding in challenge tests where noninbred survival was high, to 38.7% reduction when noninbred survival was low. Three isolates of TSV and one WSSV were used in the tests.
These results suggest that inbreeding depression becomes more serious as environmental quality (measured conventionally as the survival rate of noninbreds) goes down. An empirical relationship is provided which allows prediction of survival under various combinations of inbreeding and environmental quality.
