Nestled along the upper reaches of the Yellow River, Liujiaxia Reservoir in Yongjing County has become an unlikely epicenter of technological innovation. This Gansu Province hydropower hub now hosts thriving cold-water fish farms, where rainbow trout – often dubbed 'freshwater salmon' – thrive in crystal-clear waters maintained at stable temperatures through smart monitoring systems.
Local enterprises have developed a complete industrial chain spanning automated breeding facilities, AI-assisted feeding systems, and precision packaging lines. Advanced cold-chain networks now deliver fresh salmon products to dining tables across China within 24 hours of harvest.
"Our water quality management systems reduce waste by 40% compared to traditional methods," explains aquaculture engineer Zhang Wei, pointing to real-time oxygen level displays. The operations align with national ecological protection initiatives for the Yellow River Basin, proving environmental sustainability and economic growth can coexist.
With annual production exceeding 15,000 tonnes, the smart fisheries model has created 3,200 local jobs while maintaining water quality standards that support continued hydropower generation. Provincial authorities plan to replicate this success across northwest China's inland water systems.
