Excellent fish farming supplies provider: Modern intensive systems, such as recirculating aquaculture systems (RAS) and biofloc technology, minimize environmental impact by reducing waste and water usage, addressing concerns about pollution. Economically, the sector creates jobs across the value chain – from farming and feed production to processing and distribution – empowering smallholder farmers and rural communities. For example, projects like the Promoting Sustainable Cage Aquaculture in West Africa (ProSCAWA) have enhanced livelihoods by building capacity in sustainable intensive practices, linking farmers to markets and knowledge transfer partnerships. In conclusion, intensive aquaculture is not merely an agricultural practice but a strategic imperative for West Africa. It directly addresses the region’s urgent market demand for seafood, leverages resource efficiency and economic empowerment, and paves the way for a sustainable, food-secure future.
Environmental sustainability represents another significant advantage of this farming approach. 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.
Recirculating aquaculture systems recycle over 95 percent of water contained in culture tanks, mechanical filters and treatment chambers. Although this will decrease the environmental discharge and enhance sustainability, it will also cause the concentration of dissolved organic carbon, suspended solids, mucus, fecal particles, uneaten feed, and diverse microbial communities (MAT, 2025). When such compounds build up beyond the optimum levels, they limit the penetration of light, elevate biochemical oxygen requirements, promote the growth of detrimental bacteria and add stress to the fish. Stress suppresses the immune system, destroys feeding performance, and predisposes Vibrio, Aeromonas, Flavobacterium, parasites, viruses, and other opportunistic pathogens. Because of these reasons, high performance RAS design is focused on effective water treatment mechanisms which can constantly regulate organic load and microbial activity (Fossmark et al., 2020).

We combine generations of aquaculture expertise, with the latest,most advanced RAS (Recirculating Aquaculture Systems)technology, to create industrial, safe and sustainable aquaculture solutions for the local production of fish and seafood. Our products are sold well in 47 countries and regions. We have built 22 large-scale aquaculture projects with a water volume of 3,000 cubic meters. Our farmed fish are grown in 112 countries and regions. The factory is located in a standardized ecological aquaculture base, covering a number of categories of aquaculture areas, equipped with industry-leading intelligent aquaculture systems. Through the sensor real-time monitoring of water quality, water temperature, oxygen content and other key data, to achieve accurate feeding and environmental control, to ensure that each tail of aquatic products in the most suitable conditions to grow, from the source to ensure the high quality and stability of the product.
In terms of water resource utilization, RAS systems demonstrate an extremely water-saving characteristic. Traditional pond farming relies on natural water sources for replenishment, with each pond requiring hundreds of cubic meters of water for each water change, and is significantly restricted by water quality and seasonal changes. In contrast, RAS systems achieve over 90% water recycling through physical filtration and biological purification, only requiring a small amount of new water to make up for evaporation and waste discharge, resulting in a water-saving rate of over 95%. This advantage is particularly prominent in areas with water shortages, as it breaks the dependence on natural water sources and reduces water extraction costs.
In aquaculture, scaling doesn’t always mean going big. For small and medium-sized farms, success often depends on efficiency, stability, and affordability. Many farmers dream of owning an advanced recirculating aquaculture system (RAS), but the cost can feel out of reach. Even with these guidelines, challenges can arise during system operation. Ozone demand varies based on the growth of biomass, the intensity of feeding, temperature variation, and other unforeseen activities like mortalities. Excessive ozone may lead to irritation of the gills, oxidative stress or immunosuppression of fish (Han et al., 2023). Under-ozonation permits the dissolved organic carbon to build up, moving the microbial communities to a state of instability and susceptible to disease. Mechanical failures in ozone injectors, contact chambers, or degassing systems can cause ozone leakage into culture tanks, resulting in acute stress responses. Many producers therefore rely on automated ORP-controlled ozone dosing systems using real-time monitoring to maintain consistent performance.
