Summary
The Agriculture, Fisheries and Conservation Department (AFCD) has established a container ecological fish farming demonstration site at the Au Tau Fisheries Office in Yuen Long, introducing an innovative system that can triple production compared to traditional fish ponds while achieving zero sewage discharge through water recycling .
Key Points
- The demonstration site showcases a container ecological farming system where each 20-foot container measuring 2.4 meters wide and 6 meters tall can produce approximately 500 kilograms of fish, equivalent to 1,000 to 1,500 tilapia or ruby fish
- A 1-hectare ecological pond configured with 10 containers can yield 5 tonnes of fish, three times higher than traditional pond farming
- The system costs approximately HK$1.4 million and operates with a 24-hour smart management platform that automatically monitors dissolved oxygen, salinity, and pH levels using AI analysis
- Aquaculture effluent flows from containers through four ecological ponds for purification, where filter-feeding fish consume residual feed and waste before the water cycles back
- The system enables remote control via smartphones or tablets, eliminating the need for a large workforce to haul nets during harvest
Why It Matters
This innovation addresses critical challenges facing Hong Kong's aquaculture industry, including labor shortages and land constraints, while producing medication-free, high-quality local fish that could attract young people to the sector .
