Global aquaculture transformed thanks to investment by the Iowa Soybean Association

Two thousand years of aquaculture in China was revolutionized by one simplistic system developed by the U.S. soybean industry and supported with an investment by Iowa soybean farmers.

That’s the takeaway that soybean leaders celebrated while visiting the first Intensive Pond Aquaculture (IPA) farm in China as participants in an all-Iowa ag trade mission July 19-28.

Without a checkoff investment by the Iowa Soybean Association (ISA), that success may never have been realized, said ISA Director Jeff Jorgenson.

"With 40 percent of China imports coming from the U.S. the IPA system is going to enhance fish production into a higher inclusion of soybean meal in fish diets," said Jorgenson, an ISA director and soybean farmer from Sidney and member of the delegation visiting China. "The investment by soy checkoff dollars again will turn into more of Iowa soybeans being utilized around the world."

Two thousand years of aquaculture in China was revolutionized by one simplistic system. That is the takeaway that soybean leaders celebrated while visiting the first Intensive pond aquaculture (IPA) farm in China located outside of Shanghai.

China has practiced aquaculture for more than 2,000 years. But it wasn’t until 2013 that aquaculture was paired with IPA technologies to create a system that produced healthier fish and uses fewer resources while being fed sustainable soy grown in the United States and other countries.

The ISA in partnership with the U.S. soybean industry funded research to develop the IPA system, which has been provided to China in a technology transfer. The IPA system has been proven to triple the yield of farmed fish in existing Chinese ponds while greatly reducing the environmental impact.

"Iowa soybean farmers were the first to sponsor this technology. We are very appreciative for their generosity and support," said Jim Zhang, United States Soybean Export Council (USSEC) program manager for aquaculture in China.

IPA technology requires minimal modification to existing ponds and creates a zero water discharge system that increases yield with no negative impacts on the environment.

Water is diverted around the pond to keep it mixed. Fish are housed in concrete pens that have screens on the front and back. The circulating water creates a current that mimics the natural habitat of the fish while also removing waste manure. Other species of fish are contained in the ponds outside of the pens to feed off the nutrients.

The IPA technology also allows China’s limited water resources to be conserved and recycled. Excess waste can also be removed and used as fertilizer or biofuels.

"In 2013 when the project started there were only three cells. Now there are over 3,000 cells in China with the total construction investment, not mentioning the operational investment, is worth around $44 million," Zhang said.

The sky could be the limit for the new technology. Zhang believes the number of fish raised using the IPA system could double in the next five years.

"This technology helps to break all the bottlenecks that face China's aquaculture," he said. "Bottlenecks like labor, water, environmental and food safety."

Governor Kim Reynolds, who is leading the delegation, toured the site and fed some of the thousands of carp species raised on the farm.

"I'm extremely proud of the ISA to think that they were the original investor in this IPA. It is a win-win. Our farmers benefit from the increased use of soy, and these farms are reducing costs and expanding,

"It is a great example of what we want to see happen on the trade missions that we are a part of,” Reynolds added.

Karey Claghorn, Chief Operating Officer for the ISA, also toured the aquaculture farm powered by U.S. soybean meal.

"IPA has revolutionized the industry. It changed the way they could look at their in-pond systems," she said. "It allows them to improve water quality and environmental footprint. It was an exciting investment for us as it has worked out."

Farmers in Mexico value U.S. soymeal

The United States Soybean Export Council (USSEC) is constantly looking for new uses for soy internationally and this week members of Qualified State Soybean Boards (QSSB) were able to see firsthand how markets are growing in Mexico.

Aquaculture has been a buzz worked in the United States lately but it is a practice that has been consuming U.S. soy for many years. Countries like Costa Rica, Panama, Ecuador and Mexico import large amounts of soymeal to grow tilapia and shrimp.

Molina Farms, in the town of Jamay near Lake Chapalais, is a family farm doing just that. By importing high quality soybean grain from the U.S., they are creating large profit margins for their fresh tilapia sales and fingerling sales.

Fingerling sales is the process of selling the tilapia when they are four grams to other area producers to feed out. Molina farms are concentrating on the breeding and genetics of the tilapia to gain a premium from other farmers who don't have the facilities or genetics to start tilapia from the beginning.

The Molina Family Farm also sells fresh fish from their farm. The fresh fish sales are offered directly to consumers in the region. To keep profit margins as large as possible, Alfredo Molina invests in high quality U.S. soymeal for his rations and is also using cutting edge technology for the area.

"We spend about $1.30 per kilo of tilapia in production costs and can sell the live fish for about $4.00 a fish," Molina said, speaking through an interpreter.

Molina showed the group the finishing ponds for the tilapia where about 20,000 fish are grown per 10 foot pond. When the tilapia is ready for market it weighs between 500-600 grams or just over a pound. They use a ration of soybean made up of 40 to 50 percent soymeal. Molina said that U.S. soymeal is preferred, but due to higher prices last year, they had to import from other South American Countries.

The Biofloc system aerates the water, keeping the algae and nutrients from settling on the bottom. The system allows the fish to feed off the remaining nutrients in the water and helps build their immunity. Because of the ecological system farmers need to make sure increased algae doesn't starve the fish of oxygen. Computer systems linked to a recently installed Wi-Fi network monitor oxygen levels and can automatically adjust levels as necessary. In the past, aquaculture farmers would employee a poly fish culture, having tilapia paired in rotation with catfish or shrimp, but that cut down on production of the valuable tilapia. According to Molina, Bioflock system helps him to raise a higher quality fish in less space while increasing the growing cycle.

"The Biofloc system is rough, but we need to master it," he said.

To fill market demand Molina is looking at raising shrimp at his farm, too. He told the group gathered that his working relationship with USSEC will help him to manage the new enterprise.

“It will be trial and error at first but USSEC offers excellent information about feed rations and what other farmers are doing to be successful,”Molina said.

Heather Lilienthal, director of producer services at the Iowa Soybean Association (ISA), attended the USSEC tour in Mexico. She said seeing the uses of soy imported from the U.S. was fascinating.

"This was my first opportunity to visit an aquaculture operation and learn how this family is using soy in its feed," she said. "As they expand their operation and adapt to new technology, it reminded me of Iowa farms doing the same thing. Everyone is striving to be more efficient in order to meet growing demand for their products."
