"Haiwei-2" is a giant marine ranch carrying nearly 1 million golden pomfret fry of around 100 tonnes.

Measuring 86 meters long, 32 meters wide, and 16.5 meters high, the giant platform boasts a capacity of 30,000 cubic meters of water for aquaculture and can harvest over 500 tonnes of fish within one cycle.

Equipped with solar electricity system, the platform is self-sufficient in green energy, which enables unmanned operation and real-time remote monitoring.

"Haiwei-2" reflects Guangdong Province's years of dedicated efforts in developing deep-sea aquaculture.
