Innovative products shine at marine expo

SHENZHEN — Requiring only four staffers to breed millions of fish, Jinghai 001, a large deep-sea intelligent cage, became a hot star at the 2022 China Marine Economy Expo which concluded on Saturday in Shenzhen, a southern Chinese city in Guangdong province.

Equipped with intelligent monitoring, automatic feeding and robots capable of cleaning the nets, the 68-meter-long, 68-meter-wide and 40-meter-high smart cage with an annual capacity of 1,000 metric tons serves as a smart platform for breeding deep-sea aquatic animals.

"There are 200 sensors in the cage. Its 'fish face recognition' system can monitor the number and growth status of the fish in real time," said Pan Xilu, strategy director of Yantai CIMC Raffles Offshore Ltd, at the three-day expo.
