Smart innovation takes sweat out of farming grouper fish in China

In central China's Hubei province, a land-based grouper farm is now using technology to create the perfect farming conditions for the popular fish. The state-of-the-art facilities mimic the optimum temperature for the fish. The tanks are divided into three types to correspond to the various growth stages. According to the director, the whole breeding cycle is about 240 days, with the fish hitting the market when they weigh about a half a kilo. In about two months' time, more than 8,000 groupers grown in Wuhan are expected to go on sale.
