Skretting and Longyang Fresh Deepen Strategic Partnership

Co-creating a new future for trout farming on China’s Qinghai-Tibet Plateau

Skretting and Longyang Fresh, China’s largest trout producer, have officially signed an upgraded strategic cooperation agreement. The enhanced, three-year partnership aims to deliver precision nutrition, create supply chain synergies, and advance sustainable aquaculture practices for trout farmed on the Qinghai-Tibet Plateau. This agreement will inject new momentum into the development of China’s plateau cold-water fish industry.

A Strategic Upgrade Rooted in Proven Success

Skretting and Longyang Fresh have established a productive, long-standing collaboration in feed innovation, nutritional management, and farming practices. Over the years, the two companies have accumulated extensive experience on plateau aquatic ecosystems, trout physiology, and farming efficiency, laying a strong foundation for this strategic upgrade.

Developing Precision Nutrition Tailored to High-Altitude Ecosystems

The unique plateau environment in Qinghai Province—characterized by low temperatures, high dissolved oxygen, and low pathogen pressure—offers natural advantages for trout farming. Leveraging these ecological traits, the companies will jointly develop a precision nutrition system optimized for high-altitude conditions. Key initiatives include:

• Developing nutrition models adapted to high-altitude water ecosystems, addressing the specific physiological needs of trout.

• Utilizing global databases to optimise growth performance, health indicators, and feed efficiency.

• Implementing raw material traceability systems, reducing the environmental footprint by lowering nitrogen and phosphorus discharge.

Miyan Ying, Chairman of Longyang Fresh, commented, “This strategic upgrade builds on years of successful collaboration and a shared long-term vision. Together, we will develop precision nutrition solutions tailored to high-altitude ecosystems, strengthen supply chain cooperation, and Skretting's global strengths will be our effective support."

Strengthening the Competitiveness of China’s Plateau Trout

Longyang Fresh farms trout in glacial meltwater from the Yellow River’s headwaters in Longyangxia Reservoir on the northeastern edge of the Qinghai–Tibet Plateau. This exceptionally pure environment naturally eliminates sea-lice risks and enables antibiotic-free farming. The company utilizes a low-density farming model with triploid, infertile trout to ensure no impact on native ecosystems.

Longyang Fresh produces around 15,000 tonnes of trout annually, accounting for 98.8% of China’s total trout export volume.

Leveraging Skretting’s global supply chain network and raw material expertise, the companies will work together to build a more stable, competitive, and sustainable supply chain. These efforts aim to further enhance the global competitiveness of China’s plateau trout and support its emergence as a key source of sustainable, high-quality protein worldwide.

Maarten Bijl, Skretting CEO, stated, "We look forward to integrating our advanced global nutrition technologies and sustainability expertise with the unique conditions of the plateau, co-creating solutions that deliver long-term value for the industry. This partnership reconfirms our market-leading position... and demonstrates our commitment to increasing Skretting’s presence in China and in the wider Asian region."
