Dr. Nyan Taw, General Manager and Senior Technical Advisor
On September 28, 2009, at the World Aquaculture Society meeting in Veracruz, Mexico, I interviewed Dr. Nyan Taw, General Manager and Senior Technical Advisor at i-SHARP, a 1,000-hectare shrimp farm that is under construction in Malaysia. i-SHARP, part of the Blue Archipelago group, plans to stock its first crop in October 2010. Dr. Taw has a long history in shrimp farming and has been the technical manager for some of the largest shrimp farms in the world, including CP Prima in Indonesia, where he ran a 300-hectare biofloc project with half-hectare ponds.
Shrimp News: Tell me a little bit about the farm you are building in Malaysia.
Nyan Taw: We have a 1,000-hectare site and plan to build half-hectare ponds on 750 hectares of it. Eventually, we’ll be completely integrated with a feed mill, a breeding center, a hatchery and processing plant. We plan to build the hatchery and farm first. We’re going to share what we know with the developing shrimp farming industry in Malaysia and with shrimp farmers around the world.
Shrimp News: Where will you get your feeds?
Nyan Taw: We have lots of options, but have not made any commitments yet. We will probably build our own feed mill, along with breeding centers for Penaeus monodon and P. vannamei.
Shrimp News: How do you plan to aerate the ponds?
Nyan Taw: We will be using paddlewheels and air-injection systems. If you use air-injection systems, you can produce 1,000 kilos of shrimp per horsepower; if you use paddlewheels, you can only produce 600 kilos of shrimp per HP. But you can’t use just air-injection systems, you need to use both because they serve different functions in the pond. The paddlewheels are great for circulation, but the air-injection systems add more oxygen. With the right combination, you can increase the carrying capacity of your ponds significantly. Our new ponds will be 1.5 meters deep, so we expect to use high stocking densities.
Shrimp News: Will you be using biofloc technology on the farm?
Nyan Taw: Yes, but we’re going to start with more traditional methods and then introduce biofloc farming very slowly. We’ll try it out in a couple of ponds first. Conceptually, we really like biofloc farming because it has almost no environmental impact, and we plan to run an environmentally friendly farm. Before we turn the entire farm over to floc, however, we need to train a lot of people. Running a biofloc farm requires a whole new set of skills.
Shrimp News: How many kilos per hectare do you expect to get from your ponds?
Nyan Taw: Initially, we plan to produce about 10,000 kilos per hectare per crop. When the project is completed, we hope to produce 10,000 metric tons a year. All the ponds will be lined, so we should be able to get more than two crops a year.

Background Controls the Color of Shrimp
Abstract: The color of shrimp is dependent on the presence of carotenoid pigments (predominantly astaxanthin) in their shells and has a significant impact on their market value. In this study researchers observed that visual appearance of color in giant tiger shrimp (Penaeus monodon), when assessed using a subjective commercial grading scale, did not always correlate well with total carotenoid content. They also observed that visual appearance was affected by the background color of the tanks in which the shrimp were growing.
When shrimp were grown in black or white tanks for 28 days, even though they had similar mean total astaxanthin contents in their tails, those grown in black tanks were much more orange/red when cooked, compared to those from the white tanks. The pigments were mainly located in the cephalothorax, abdominal epidermal layer and abdominal exoskeleton. Light microscopy showed an even distribution of pigment in the epidermal layer of the more colored shrimp when compared with concentrated pigment areas in the lighter-colored shrimp. Non-esterified astaxanthin was the major carotenoid present (50%) in all body locations in shrimp from black tanks with the remainder being made up equally of astaxanthin, mono-esters and di-esters. However, for shrimp from white tanks, non-esterified astaxanthin accounted for just 12–13%, with the mono-esters reaching about 60% of the total present.
In a separate experiment, the researchers demonstrated that changes in background color caused a rapid change in visual color. When shrimp were moved from a white to a black tank, there was a significant increase in grade score within an hour without any change in astaxanthin content. Color improvement continued to increase over 168 hours. Moving shrimp from a black to a white tank resulted in a reduction in grade score, but the change was much less rapid.
This work suggests that, provided shrimp have an adequate content of astaxanthin in their diets, it is possible to improve their overall appearance (raw and cooked) by manipulating background color before harvest.

Expalsa’s Organic Shrimp Garners 25% Higher Price
Demand for organic shrimp is strong again after taking a hit at the beginning of the worldwide economic slump, says Juan Fernando Gomez Behr of Expalsa’s export department. “Since last October, there was a drop in demand. But we are seeing a recovery now.” The Ecuador-based firm sells its own Naturland-certified organic shrimp (20% of sales) and non-organic shrimp (80% of sales) that it purchases from other Ecuadorian farms.
Every month, Expalsa ships 150 twenty-metric-ton containers of shrimp around the world, said Gomez. Each container is worth around $100,000 and the company’s annual shrimp sales are around $180 million. This doesn’t take into account feed sales or sales from different arms of the Expalsa group, said Gomez, although he declined to reveal the actual sales figure for the company.
Some of its major customers are Birds Eye Iglo, the Alfesca Group, Lyons Seafood, Italian foodservice firm Skalo and German wholesaler Ristic. The company’s main markets for organic shrimp are Germany, the United Kingdom, Canada, Switzerland and France. Its main sales for the non-organic product are Italy, United States, Spain, France and the United Kingdom, and it recently started selling to Egypt, said Gomez—adding that prices for organic shrimp are around 25 percent higher than those for non-organic shrimp!
Expalsa sells shrimp in various forms, from a new individually quick-frozen (IQF) brine frozen product, which it markets in Spain and Portugal, to value-added products in demand in Italy. In Ecuador, Expalsa operates a value-added processing plant that employs 2,000 people.

Hawaii—Macky’s Shrimp Truck and Chen-Lu Shrimp Farm
“If you had told me that one of my best meals in Oahu would be from a truck parked on the side of the road, I would have thought you were losing your mind. Or maybe the fact that we sought out this oddity meant I was losing my mind. Either way, we went, we ate, we loved it and we went back two days later. There are several of these ‘establishments’ scattered across the North Shore of Oahu. Most are located in Kahuku, but we were interested in sampling the offerings at Macky’s in Hale’iwa. We were skeptical but then extremely pleasantly surprised. Upon pulling into the parking lot (66-632 Kamehameha Highway), you feel like you are entering a time warp from the Woodstock concert era. A crazily painted truck with a service window on the side is where you step up and place your order. There are covered picnic tables set alongside the truck and that is pretty much it. If you can get past the unusual setting you are in for a real treat. Macky Chen himself will greet you with enthusiasm and immediately makes you feel right at home, even if you are standing in the middle of a parking lot. ...They do not accept credit cards, so take cash. Each plate was about $12 and for that you got roughly a dozen decent sized, perfectly cooked shrimp.”
Chen gets his shrimp from the Chen-Lu Shrimp Farm.

Louisiana—Outback Restaurants to Serve Only Wild Shrimp
The Associated Press reports:
The Outback Steakhouse restaurant chain is scrapping plans to serve imported shrimp in Louisiana. On October 7, 2009, Bruce Attinger, a partner in the Florida-based company, said that it had planned to begin selling less costly foreign shrimp next month. But Attinger said he decided that was a bad idea after he heard about hardships of the state’s industry, which is struggling to compete against imported product.
Governor Bobby Jindal, who called a news conference at the Governor’s Mansion to announce the company’s decision, said he hopes other restaurant chains will also commit to selling Louisiana shrimp.

Louisiana—New Orleans, NFI Annual Meeting
At the National Fisheries Institute (NFI) annual meeting in New Orleans (September 2009), Warren Connelly, an attorney at Akin Gump (based in Washington, DC), which represented some Ecuador-based shrimp companies in the dumping case, said the dumping complaint filed by USA shrimp fishermen and producers against foreign shrimp suppliers had “absolutely no effect” on market conditions.
“Total import volumes and prices are about the same if not lower, so that leads us to conclude it can’t be dumping that’s causing the problems for domestic suppliers,” Connelly said.
Connelly said revoking the dumping duties against foreign suppliers won’t have any meaningful effect on the USA industry. “There may be some slight shifting of supplies, but that’s about it as far as we can tell,” he said.
Still, it’s worthwhile to pursue revocation of the duties when the International Trade Commission begins its sunset review of the duties in January 2010, said Connelly. “There is a chance the order may get revoked,” he said. “My recommendation is we ought to take our best shot at it.”

Texas—Aquaculture of Texas, a Freshwater Prawn Hatchery
In Texas, research on the freshwater prawn (Macrobrachium rosenbergii) was abandoned in the 1970s, but Craig Upstrom of Aquaculture of Texas, Inc., a freshwater prawn hatchery in Weatherford, apparently didn’t get the message and has developed a successful and sustainable prawn hatchery that has survived in a tough industry for 21 years, making it the oldest and largest freshwater prawn hatchery in the USA. Located in a 1,394-square-meter metal building on Interstate Highway 20 just west of Fort Worth, Upstrom manages the hatchery and is its majority shareholder. He produces six million postlarval shrimp each spring. Upstrom says it takes about $100,000 to pay the bills each year, but somehow it gets done. Two other prawn hatcheries have been built in the eastern USA recently, and they have cut into Upstrom’s sales.
Because he runs the hatchery himself, with a part-time assistant, Upstrom needs more time to work on genetics and developing a substitute larval diet to replace expensive Artemia. Dr. Delbert Gatlin of Texas A&M University’s Wildlife and Fisheries Sciences Department plans to visit the hatchery and explore the possibility of placing some undergraduate interns there during the summer to work on needed research.
In Texas, farmed prawns sell for about $17.60 a kilogram.

Virginia—Biofloc Feed “Truly Exceptional”
Abstract: Microbial flocs produced in suspended growth bioreactors could offer the shrimp industry a novel alternative feed. In this study, microbial flocs were produced in sequencing batch reactors (SBRs) using tilapia effluent and sugar as a growth media. It was determined that 1 kg of microbial floc could be produced per 1.49 kg of sucrose.
The microbial floc was tested as an ingredient for shrimp feed over a 35-day feeding trial. Two control diets without microbial flocs were compared to three diets with microbial flocs. Control 1 and microbial floc diets (diets 1–3) were formulated to be equivalent for levels of crude protein, total fat, crude fiber, calcium, magnesium, phosphorus, potassium and sodium. Controls 1 and 2 did not contain microbial flocs and differed slightly from each other in soybean oil, krill meal and mineral/salt levels. For diet 1 (microbial floc 7.8%) and diet 2 (microbial floc 15.6%), soybean protein isolate was replaced with microbial flocs at a 7.8 and 15.6% inclusion level on a dry matter basis. For diet 3, fishmeal was replaced with microbial flocs at 7.8% and fish oil at 0.50% (microbial floc 7.8% + fish oil).
Four juvenile Litopenaeus vannamei were stocked per tank and each dietary treatment was tested in 12 replicates over a 35 day feeding trial. No differences were observed between final survival rates (93 to 100%) in any of the dietary treatments. Growth (weight gain per week) for control 1, control 2, diet 1, diet 2 and diet 3 were respectively 1.09 ± 0.14, 0.88 ± 0.14, 1.64 ± 0.03, 1.61 ± 0.03 and 1.63 ± 0.04 grams per week. The total gain in weight for the three diets containing microbial floc of 8.07 to 8.18 grams in five weeks with an initial weight of 0.44 ± 0.005 grams is truly exceptional. Tukey’s HSD (Honestly Significant Differences) test revealed that each of the three microbial floc diets significantly (P < 0.01) outperformed each control in terms of weight gain per week with no differences in survival.

Organized Shrimp Thieves Know When to Hit Farms
Despite relentless efforts by shrimp farmers, organized shrimp thieves continue to prey on ponds that are ready for harvest.
Nguyen Van Be, a shrimp farmer in Bac Lieu Province (Mekong Delta), has been hit three times and lost a ton of shrimp. He said, “The thieves were also watching me while I was watching out for them and they would make use of any moment I leave the ponds, to have lunch or dinner for example.”
The thieves know which ponds are ready for harvest, said Quach Thanh Moc who has hired four men to guard his 1.5-hectare shrimp farm.
Farmer Trinh Thanh Lam has spent thousands of dollars fencing his ponds, hanging electric lights around them and positioning three guards, but these measures have not been foolproof.
Le Anh Xuan, who has invested more than $5,600 to light up his shrimp ponds at night and hired guards who are housed in ten tents pitched around the ponds, said, “I am still robbed once in a while.”
Police officer Truong Minh Khoi, who has chased shrimp thieves several times, recalled one case in March 2009 when more than 20 thieves armed with swords plotted to rob a shrimp farm. They even brought mosquito nets to protect themselves while they waited for the right time to attack. Outnumbered, Khoi said his force fired its guns into the air and scared off the attackers, except for one, who had fallen asleep before the raid and slept through all the commotion.
A gang of seven shrimp thieves that was caught early in 2009 told police that one member would keep watch, two would scatter feed to attract the shrimp, two would work the nets—and two would wait on motorbikes to drive others away at short notice.
