Yisheng used to pay between 10,000 and 20,000 yuan ($1,400 and $2,800) each for macaques, Shao said.
Now each animal is worth 100,000 yuan, according to Shao.
Chinese labs mainly use rhesus and cynomolgus macaques, farmed in the country’s southern provinces.
China is a large provider of lab monkeys, exporting 20,000 of them last year and using 18,000 in local research, said Liu Yunbo, chairman of Beijing HFK Bioscience, a lab animal provider.
“This year’s consumption is quite large, so the supply is not enough,” he said.
