Under the lens of sustainable innovation, the freshwater pearl mussel composite fishery system in Deqing County, Huzhou, Zhejiang Province on the Chinese mainland is making waves. It has just been designated as a Globally Important Agricultural Heritage System (GIAHS) by the FAO, marking the second GIAHS in Huzhou and the 25th in China.
Local representatives accepted the GIAHS certificate at a ceremony in Rome, celebrating a tradition that blends aquaculture and cultural heritage. This polyculture approach places pearl mussels and native fish species in harmony, creating a resilient and resource-efficient ecosystem.
A Blend of Tradition and Ecology
For generations, residents of Deqing County have refined techniques that let mussels purify water naturally while supporting healthy fish populations. Rather than relying on monoculture ponds, this composite system boosts biodiversity, reduces the need for chemical inputs, and preserves time-honored knowledge.
Global Impact
- Climate resilience through low-impact farming practices
- Strengthened livelihoods by diversifying income sources
- Eco-tourism appeal for travelers and digital nomads
As global communities seek solutions for food security and environmental challenges, Deqing County's fishery offers a blueprint for integrating traditional wisdom with modern sustainability. Entrepreneurs, thought leaders, and eco-enthusiasts alike can draw inspiration from this living heritage system.
