Thailand’s change in shrimp production strategies over the years has paid off, and this year producers are expecting a 10-20 percent increase in production, said Siam Canadian General Manager Satasap Viriyanantawanit.
“We used to use a high density, super intensive farming method and we had to use an excessively high volume of feed, which caused issues,” he told IntraFish.
However, upon switching to lower density stocking for the shrimp ponds, the survival rate changed from 75 percent to 90 percent.
“We now have the same output despite lower stocking because the survival rate is higher,” he said. “Also, the cost of feed is much lower now because 60 percent of farming costs is the feed.”
This change came about based on research, but especially because of past issues with EMS, which at times lowered the survival rate to 25 percent.
“EMS made farmers change, become flexible and open to new research and technology,” said Viriyanantawanit.
Thailand’s largest shrimp export market is the United States. About 40 percent of global production goes to the United States.
Likewise, most shrimp produced in India goes to the United States, Siam Canadian General Manager Awadesh Shrivastava said. The most popular shrimp sizes out of India to the United States are headless 16/20, 21/25 and 26/30.
About 20-25 percent goes to Asian countries, mostly China and Vietnam, he told IntraFish.
