At Liujiaxia Reservoir in Yongjing County, northwest China's Gansu Province – a major hydropower hub on the upper reaches of the Yellow River – crystal-clear water, stable temperatures and rich oxygen levels create ideal conditions for cold-water fish such as rainbow trout, often called freshwater salmon. Leveraging these natural advantages, the region has built a full industrial chain spanning breeding, farming, processing, packaging and distribution, setting a benchmark for inland cold-water aquaculture in northwest China.

In recent years, digital tools and modern facilities have enabled a shift towards intelligent, eco-friendly aquaculture. From automated processing plants to cold-chain logistics networks, neatly packed salmon products are shipped nationwide with efficiency and precision.

By aligning with ecological protection and high-quality development of the Yellow River Basin, it turns the river's waters into a sustainable source of prosperity and well-being for local communities.
