Mr. Pham Huy Hung, Head of the Economic, Infrastructure and Urban Planning Department of Ha An Ward, said: The Ha Long Green complex urban project alone requires over 3,000 hectares of land in the ward, of which more than 1,000 hectares are for aquaculture. Therefore, while Ha An had over 3,000 hectares for aquaculture, mainly shrimp farming, before 2025, it currently has only over 2,000 hectares, and the aquaculture area, including shrimp farming, will continue to decrease in the future.
In this context, Ha An encourages aquaculture facilities to increase the application of modern farming technologies, reduce acreage, and increase the scientific and technical content. Solutions implemented by Ha An ward to support aquaculture farmers include quickly completing land allocation and leasing procedures for aquaculture, ensuring water supply and management to allow shrimp farms to invest confidently, verifying the origin of farmed shrimp, facilitating product circulation, and thereby increasing the value of shrimp. Along with this, shrimp farms in Ha An ward have clearly identified the need for technological innovation, shifting from extensive and semi-intensive farming to intensive and super-intensive farming.
Currently, the entire ward has approximately 150 hectares invested in industrial-scale shrimp farming, with modern infrastructure and advanced farming technology. A prime example is Tan An Aquatic Products Joint Stock Company, currently one of the largest shrimp farming units in Ha An. On an area of 35 hectares, Tan An Aquatic Products uses multi-stage farming technology, raising shrimp in various small ponds, including ponds and tanks for shrimp larvae and first and second-stage commercial farming ponds; it also utilizes microbial technology to treat organic waste in the ponds, transforming it into a protein-rich food source for the shrimp…
Mr. Nguyen Van Hung, from Zone 3, Ha An Ward, has boldly switched from a three-stage shrimp farming model to a recirculating aquaculture system (RAS). This is currently the most advanced shrimp farming technology, utilizing sensors and an Internet of Things (IoT) system to reuse farming water, comprehensively control environmental factors such as pH, temperature, dissolved oxygen concentration, ammonia, etc., and provide automatic feeding via sensors and environmental warnings using AI software. Mr. Nguyen Van Hung stated: "High-tech shrimp farming can better control diseases, shorten farming time, and increase the number of farming cycles per year, thereby optimizing productivity and minimizing risks. Microbial technology for treating organic waste in the ponds also helps reduce feed costs and minimize water changes. The closed-loop recirculating aquaculture system (RAS) solves the problem of controlling environmental parameters, one of the key factors determining success in today's high-density farming conditions."
Mr. Ngo Hung Dung, Director of Tan An Aquatic Products Joint Stock Company, said: "Innovating aquaculture technology and using technology to compensate for the current land area is an inevitable direction. The results from high-tech shrimp farming models have yielded up to 30 tons/hectare/crop, and multiple crops can be produced per year, including the winter crop. This is sufficient proof of the superiority in terms of yield and value, which is 3-5 times, or even dozens of times, higher than conventional shrimp farming models. This is the motivation and confidence for shrimp farmers to boldly switch to high-tech shrimp farming."
Through adaptations to the new situation, Ha An's aquaculture sector expects to maintain the production and quality of aquatic products, with a specific target for 2026 of over 2,000 tons, accounting for over 75% of the agricultural production value of the ward, creating jobs and stable income for thousands of local workers.
