China's largest semi-submersible integrated fish farming platform has officially been put into operation in Sanya, south China's Hainan Province, marking the stocking of its first batch of fry.
The platform, named "Xinhuan No. 1," has a total aquaculture water volume of 64,000 cubic meters, roughly equivalent to 20 Olympic-sized swimming pools, and is capable of producing 4,000 tons of fish per year.
Crew members on the platform said the first batch of roughly 3 million fry will be released over a period of 20 to 30 days beginning Friday last week when the system went into formal operation. The fry consist mainly of fourfinger threadfin and pearl grouper.
After about 10 months of farming, the fish are expected to grow to an average weight of more than 0.5 kilograms each, ready to reach consumers' dinner tables.
The Xinhuan No. 1 operates a rotational stocking and harvesting system. Fish will be harvested in batches at appropriate times, with new fry restocked to maintain optimal density in the cages, a strategy designed to maximize annual yield.
According to the project's lead manager, in addition to fish farming, the platform will also support agriculture-tourism integration, including recreational fisheries, fishing, and sightseeing tours.
"We raise two batches of fish each year, with 2,000 tons per batch, adding up to 4,000 tons annually. While we focus on raising quality fish, our second line of business is a service model that combines recreational fishing and sightseeing tours," said Li Xihuan, general project manager of "Xinhuan No. 1."

China's total electricity consumption exceeded 8 trillion kilowatt-hours in the first three quarters with stable grid operations, while residential power use edged down due to a high base from last year's extreme heat, the National Energy Administration (NEA) said Friday.
Total power consumption reached 8.07 trillion kilowatt-hours from January to September, up 3.9 percent year on year. Electricity use in the primary, secondary and tertiary industries grew 3.4 percent, 4.1 percent and 6.8 percent, respectively, while residential electricity consumption fell 0.3 percent.
"In the January-September period, residential electricity consumption declined. This was mainly because 2025 was China's most extreme high-temperature year since 1961, creating a significantly high baseline for cooling loads last summer. During this year's summer period, the national average temperature was lower than a year earlier, with more typhoons making landfall, staying longer and bringing broader rain belts. The cooler temperatures reduced cooling loads in the third quarter, driving down residential electricity use," said Xing Yiteng, deputy director of the Department of Development and Planning at the National Energy Administration.
Power usage patterns showed a clear divergence between old and new growth drivers, with high-tech sectors becoming the primary drivers of overall electricity growth. In the first three quarters, declines in industrial electricity consumption were mainly concentrated in real estate and energy-intensive industries, with cement, glass and construction down 8.1 percent, 10.7 percent and 8.7 percent, respectively.
By contrast, electricity use in high-tech and equipment manufacturing combined expanded by nearly 10 percent, while internet data services and EV charging and battery-swapping services jumped 41.6 percent and 55.4 percent, respectively, maintaining strong momentum.
