This video presents a summary of key insights and forward-looking actions from the closing session of the 3rd High-Level Meeting on Aquaculture Transformation in the Asia-Pacific Region. It highlights the critical role of low-cost fish for food security, the need for intuitive technologies suited to smallholders, and the barriers posed by regulation and financing gaps. Key themes include the importance of genetic improvement, knowledge-based farming, improved access to expertise, and alignment of incentives for sustainable and profitable aquaculture. The session emphasises inclusive investment strategies, farmer integration into financial systems, and the need for regional coordination and collaboration to drive transformation through 2030.

Shrimp aquaculture in Saudi Arabia has evolved significantly since its inception in the 1990s, transitioning from freshwater tilapia farming to large-scale marine shrimp production, primarily focused on Penaeus vannamei. This shift was driven by market demand, environmental suitability, and the impact of disease outbreaks such as white spot syndrome. However, early development faced major biosecurity challenges, including inadequate regulation, limited local hatchery capacity, insufficient disease monitoring, and a lack of trained personnel.

In recent years, the Ministry of Environment, Water & Agriculture (MEWA) has undertaken a comprehensive reform of shrimp farm biosecurity, aligned with the country’s Vision 2030 objectives. This includes regulatory controls on live shrimp imports, development of disease monitoring infrastructure, biosecurity training, and enhanced collaboration with private sector and academic institutions. MEWA has also promoted technology transfer, workforce development, and sustainable hatchery expansion. While progress is evident, future priorities include improving local broodstock availability, expanding real-time disease diagnostics, and strengthening biosecurity human resource capacity to ensure long-term industry stability and resilience.

The increasing demand for cost-effective and sustainable aquafeeds has prompted interest in alternative protein sources to replace fishmeal. Wolffia globosa (duckweed), is a fast-growing, rootless duckweed with high protein content and favorable nutrient composition, offers significant potential as a feed ingredient in aquaculture. Studies conducted at the College of Fisheries, Central Agricultural University in Tripura, India, demonstrated the feasibility of using Wolffia as a primary feed for rohu fry, yielding promising growth and health outcomes comparable to those achieved with conventional formulated feeds.

Beyond its nutritional value, Wolffia contributes to environmental sustainability through phytoremediation, improving water quality in aquaculture systems, and reducing the reliance on fishmeal and chemical fertilisers. Challenges remain, particularly due to anti-nutritional factors common in plant-based feeds, but these can be mitigated through thermal and enzymatic treatments. With proper processing, Wolffia globosa emerges as a viable, eco-friendly protein source for aquaculture, supporting both profitability and environmental stewardship.
