Recirculating Aquaculture System - Global Industry Market Analysis Report 2020-2031

Recirculating Aquaculture System (RAS) is an advanced technology that achieves high-density, sustainable aquaculture through water recycling treatment. It is widely used in the commercial production of fish (such as salmon, tilapia, sturgeon), shrimp (such as prawns), shellfish (such as abalone) and ornamental fish. Its core components include biological filters (nitrifying bacteria to remove ammonia nitrogen and nitrite, the conversion rate is more than 95%), mechanical filters (sand filtration or drum filtration to remove suspended matter, particle capture rate> 90%), UV/ozone disinfection (kill pathogens, bacteria removal rate> 99.9%), water temperature regulator (heat pump to maintain the optimal temperature of 20-28 ° C), dissolved oxygen equipment (maintaining dissolved oxygen> 6 mg/L) and water pumps (circulation flow rate can reach 100-500 L/min). Through 90%-95% of water recycling, water consumption is significantly reduced (daily water exchange rate<1%, saving 98% of water resources compared to traditional floating aquaculture). The RAS system can treat 100-1000 m³/day of water, supporting high-density farming (fish density 50-100 kg/m³, shrimp density 5-10 kg/m³). For example, in Norwegian salmon farming, RAS supports an annual production of more than 100,000 tons, reducing dependence on marine cage farming and reducing the risk of marine pollution and disease transmission; in indoor shrimp farming, it increases the survival rate to 80%-90% by precisely controlling water quality (pH 7.5-8.5, ammonia nitrogen<0.1 mg/L, nitrite<0.05 mg/L), which is significantly higher than traditional farming (50%-60%). The design of the system needs to be customized according to the fish species and farming goals. For example, salmon requires low temperature (12-16°C) and high dissolved oxygen (>8 mg/L), while tilapia requires high temperature (26-30°C) and low flow rate (<0.5 m/s). The production process needs to be equipped with an automated monitoring system (including pH, DO, temperature and turbidity sensors) and a backup power supply (UPS or diesel generator) to ensure stable water quality and continuous operation of the system.

The application of recirculating aquaculture systems in aquaculture has been outstanding, but its advantages and disadvantages have triggered extensive discussions on technology, economy and environment. Supporters believe that its high efficiency and environmental protection provide solutions for the sustainable development of aquaculture. For example, the RAS system reduces wastewater discharge to 1%-2% of traditional aquaculture through water recycling and waste treatment (biofilters convert ammonia nitrogen into harmless nitrates), significantly reducing pollution to natural water bodies; in high-density aquaculture, its unit area yield (50-100 kg per square meter per year) is 10-20 times that of traditional pond aquaculture, supporting food security and protein supply; in terms of disease control, its closed environment and disinfection system reduce the risk of pathogenic bacteria (such as Vibrio and viruses) transmission to less than 0.1%, reducing the use of antibiotics (<0.1 g/kg fish), and meeting the food safety standards of the EU and FDA. In addition, RAS systems can achieve year-round production without seasonal and climate restrictions, such as breeding tropical fish species in cold regions (such as Canada) through temperature control, or establishing indoor farms around cities (reducing transportation carbon footprint). However, critics point out that the initial investment and operating costs of RAS systems are high. It takes about $10 million to $20 million to build a medium-sized system (500 tons per year), including water treatment equipment (40% of the total cost), building facilities (30%) and automation systems (20%). The operating costs are also high. The power consumption per ton of fish is about 2000-3000 kWh (mainly used for water pumps and temperature control). Combined with feed and labor costs, the production cost per kilogram of fish is about $4-6, which is much higher than traditional farming (2-3 US dollars/kg). In addition, the system has high technical requirements, water quality parameters need to be monitored in real time (a drop in dissolved oxygen of 1 mg/L may cause fish to suffocate), the maintenance of the biofilter is complicated (the strain needs to be replenished regularly), and once a failure occurs (such as power outage or pump failure), it may cause the death of all fish in the pond, which is a high risk. Some users also reported that the RAS system has limited adaptability to certain fish species. For example, some deep-sea fish (such as tuna) are difficult to farm in RAS because they require high flow rates and high oxygen environments. In addition, improper waste treatment (filter residue and sludge) may lead to secondary pollution, and solid waste treatment facilities are required.

In terms of the market, the demand for recirculating aquaculture systems is closely related to the rapid growth of the global aquaculture industry, environmental policies, and consumer demand for sustainable seafood. Europe, especially Norway, has become the main market for RAS due to its leading position in salmon farming (production is expected to exceed 2.5 million tons in 2025) and strict environmental regulations (the Norwegian Aquaculture Act restricts marine pollution). Norwegian companies (such as AquaMaof and Nordic Aquafarms) widely use RAS in land-based farming, and the government promotes its popularization through subsidies (about US$500 per ton of fish). The North American market focuses on high-end aquatic products and urban agriculture. For example, the United States and Canada promote RAS in salmon, tilapia and ornamental fish farming, and the market size is expected to reach US$1 billion in 2025. The Asian market, especially China, has a rapidly growing demand for RAS due to its world-leading aquaculture production (expected to exceed 80 million tons in 2025) and water shortage (only 2,000 m³ per capita). Chinese companies (such as Tongwei Co., Ltd. and Haida Group) use RAS in shrimp and sturgeon farming, and the government supports technology promotion through the Green Development Plan for Aquaculture. The growth of market demand is also driven by the trend of sustainable development and food safety. Consumers are increasingly inclined to choose green aquatic products without antibiotics and low pollution. The low environmental impact and high quality characteristics of RAS meet this demand. However, the market development also faces several challenges, including high initial investment that may limit the entry of small and medium-sized farmers, high operating costs that may affect profitability (need electricity price subsidies or scale to reduce costs), technical complexity that may make promotion difficult (need to train professionals), and the low cost of competing technologies (such as marine cage farming or semi-closed systems) that may divert the market.

In the future, the development of recirculating aquaculture systems may focus more on cost reduction, intelligence and ecological integration. The development of low-energy equipment (such as efficient water pumps and LED lighting) and renewable energy power supply (solar or wind power to drive RAS) may reduce operating costs by 20%-30% and improve economic efficiency. The introduction of smart technologies, such as optimizing water quality management and feeding strategies through the Internet of Things (IoT) and artificial intelligence (AI) (precision feeding reduces feed waste by 10%-15%), may improve aquaculture efficiency and survival rate. The potential in the ecological field is worthy of attention. For example, RAS can be combined with aquaponics to use fish waste to provide nutrients for plants and achieve dual benefits of aquaculture and agriculture. In addition, its technology can also be extended to the field of marine protection, such as for the breeding and release of endangered fish species. However, the industry still needs to face some challenges, including how to deal with the economic risks of high investment (government financing support is required), the educational needs for technology popularization (a training system needs to be established), and the environmental protection requirements of waste management (sludge needs to be recycled). In general, the recirculating aquaculture system has broad market prospects due to its environmental advantages and high efficiency in sustainable aquaculture, but its future development needs to rely on technological innovation (intelligence and low energy consumption), policy support (subsidies and tax incentives) and market education (raising consumers' awareness of green aquatic products) to cope with the challenges of cost and technology promotion.
