Land-based enclosed systems effectively control water exchange and discharge, minimising pollution risks to surrounding natural water bodies. This makes them particularly suitable for regions within Central Asia characterised by fragile ecosystems and precious water resources. Furthermore, waste generated during cultivation can be centrally collected and treated, with portions converted into agricultural fertilisers, enabling resource recycling and aligning with green aquaculture development principles. In summary, the galvanised metal canvas pond model offers Central Asia’s rainbow trout industry an efficient, flexible, and environmentally sound development pathway. It not only overcomes local natural constraints and resource limitations but also enhances the sector’s resilience and market competitiveness by improving management precision and system durability. In the future, with further optimisation and wider adoption of this technology, it is anticipated to establish a replicable and sustainable aquaculture model across Central Asia and beyond, injecting new vitality into regional food security and economic development.

The significant increase in unit output efficiency greatly enhances economic benefits. Traditional pond farming has a low density, with an average yield of only a few hundred kilograms per mu, and is limited by land area in terms of large-scale expansion. RAS systems can increase space utilization through three-dimensional farming and multi-layer layouts, with a farming density 5 to 10 times higher than that of ponds, and an equivalent yield of several thousand kilograms per mu. At the same time, precise feeding and stable environmental conditions reduce feed waste and disease losses, increasing the feed conversion rate by 15% to 25% compared to traditional methods, significantly reducing the production cost per unit product. Export potential will expand as West African producers meet global standards for quality and sustainability, tapping into European and global markets hungry for responsibly sourced seafood.

Stabilization of a recirculating aquaculture system (RAS) as a zero-outbreak system has become a fundamental objective in modern aquaculture systems engineering, especially in a high stocking rate and low water exchange rate intensive commercial production system where microbial growth conditions are optimal. As aquaculture systems expand at a global level, maintaining water quality, stabilizing microbial populations, and eliminating pressure of pathogens inside highly controlled systems has become a key economic consideration and viability in the long term(Li et al., 2023). Zero-outbreak facility is the one that can maintain the well-being of fish and the environmental balance with the absence of disease incidents that interrupt the cycles of production and cause a high level of mortality. This stability cannot be accomplished through mere water exchange but rather a rigorous water treatment scheme that is scientifically based. The dual ozone biofilter method is one of the most effective methods employed in modern aquaculture and it is a synergistic process comprising of both advanced oxidation and biological nitrification to ensure the water quality, prevent pathogens, and achieve consistent environmental conditions, which is vital to the success of long-term systems (Preena et al., 2021).

Technological stability is also a key concern. Although current flow-through aquaculture technology is relatively mature, it can still be affected by various factors in practical applications, such as equipment failure, sudden changes in water quality, and climate change. Problems with the technical system can lead to a deterioration of the aquaculture environment, hindered fish growth, and even large-scale disease and mortality, causing significant losses to fish farmers. Furthermore, as people’s demands for the quality and safety of aquatic products increase, flow-through aquaculture systems face new challenges in ensuring the quality and safety of aquatic products. Continuous optimization of aquaculture processes, strengthened management of feed and medication use, and improved quality testing and traceability systems are necessary.

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.
