A fleet of 30 boats sail toward the port in Sanya, Hainan province, July 29, 2012. The fleet, one of the largest in the history of Hainan, set sail for an 18-day fishing operation in the South China Sea on July 12. The boats reached waters near Yongshu Reef, Zhubi Reef and Meiji Reef in Nansha Islands. According to official figures, the waters around Sansha have a potential fishery volume of 5 million metric tons every year, yet Hainan has only 80,000 metric tons of fishing production currently.
