Fish farming supplies factory today: Excellent water quality, safeguarding health – High-quality water is crucial for the healthy growth of fish, and flow-through aquaculture systems have a natural advantage in this regard. Flowing water acts like a diligent “cleaner,” promptly carrying away fish waste and uneaten feed, greatly reducing the risk of water pollution. Compared to traditional pond aquaculture, flow-through aquaculture systems offer more stable water quality, higher dissolved oxygen levels, and lower concentrations of harmful substances such as ammonia nitrogen and nitrite. This superior water environment not only reduces the likelihood of fish diseases and the need for medication but also aligns with the fish’s natural swimming instincts, ensuring their vitality and resulting in healthier, more delicious, and more competitive fish in the market.

In terms of durability and maintenance, galvanised metal frames offer excellent corrosion resistance and structural stability, well-suited to Central Asia’s environment characterised by significant diurnal temperature variations and arid conditions. The outer waterproof canvas, typically manufactured from polymer materials, provides outstanding impermeability and resistance to ageing, ensuring a long service life. This reduces frequent repair and equipment replacement costs associated with pond leakage or structural damage. From a long-term operational perspective, this pond model reduces overall costs while enhancing the reliability and continuity of the aquaculture system.

Ozone plays a central role in addressing this challenge. As one of the strongest oxidants used I aquaculture water treatment, ozone rapidly breaks down dissolved organic matter, color pigment, fine colloids, and microbial contaminants. Numerous aquaculture studies, including those in salmonid, tilapia, and marine finfish production, have shown that ozone application can significantly improve water clarity, increase ultraviolet transmittance, depresses heterotrophic bacterial population, and reduces concentration of ozone sensitive pathogens. Because ozone decomposes into oxygen, it avoids leaving harmful chemical residues in the system. This is its distinctive feature from chlorine-based disinfectants, which leave persistent byproducts incompatible with recirculating systems. Ozone thus functions as a rapid, residue-free oxidant capable of clarifying water and decreasing pathogen pressure upstream of the biofilter(Xue et al., 2023).

The lightweight flow water system isn’t just a cheaper version of RAS – it’s a strategic choice for growth. It gives small and medium-sized farms the power to produce more with less, while maintaining stable water quality and lower costs. By blending smart control with practical design, it paves the way for efficient, data-driven, and sustainable aquaculture in every region. Looking to upgrade your farm without breaking the bank?

In Saudi Arabia, a land once renowned for its oil, a “blue revolution” is quietly taking shape. Amid the traditional sandy deserts and barren lands, modern galvanized sheet fish pond farms are scattered like stars, forming a striking landscape. Among them, the high-density farming model of tilapia and catfish has achieved an industry miracle of “80 kilograms of fish per cubic meter of water”, and the product advantages and market returns behind it are astonishing.

The precise control of the farming environment is the core competitiveness of RAS systems. Traditional pond farming is greatly affected by natural fluctuations in weather, water temperature, and water quality, leading to frequent problems such as insufficient dissolved oxygen and pH imbalance, which cause strong stress responses in the farmed organisms and increase the risk of disease outbreaks. RAS systems use intelligent devices to monitor and control key indicators such as water temperature, dissolved oxygen, and ammonia nitrogen in real time, maintaining a stable water environment and keeping the farmed organisms in the best growth state. Data shows that the survival rate of fish and shrimp in RAS systems is 20% to 30% higher than that in traditional ponds, and the growth cycle is shortened by 15% to 20%.

Abroad, recirculating aquaculture systems have also undergone a long development process. Since the 1960s, developed countries in Europe and America have begun exploring land-based, factory-style recirculating aquaculture systems, a more advanced form of flowing water aquaculture. Early land-based factory-style recirculating aquaculture systems were relatively simple, mainly establishing preliminary water circulation paths and using simple filtration devices to perform preliminary treatment of the aquaculture water, achieving limited water purification and recycling. At this stage, the scale of aquaculture was small, the technology was not yet mature, and it was more of an emerging concept and experiment, conducted experimentally in a few research institutions and farms.
