Fish farming supplies manufacturer and supplier with Wolize: 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.
Intensive aquaculture delivers unique advantages that address West Africa’s specific constraints and opportunities. Its core strength lies in resource efficiency: it produces significantly higher yields per unit of water and land compared to traditional farming or wild fishing, a critical advantage in a region where arable land is limited but water resources are abundant – including massive reservoirs like Lake Volta, the world’s largest man-made lake by area. Species such as tilapia, catfish, and white-legged shrimp thrive in high-density conditions, making them ideal for intensive systems while requiring lower protein intake, reducing reliance on expensive fishmeal. Unlike seasonal wild fishing, intensive aquaculture enables year-round production with predictable yields, stabilizing food supplies and prices for consumers while providing consistent income for farmers.
UV strategies are also determined by species and production models. Salmon smolt systems have high requirements of 60-120 mJ since they are prone to protozoans and monogeneans (RK2, 2025). Farms of tilapia, which must operate in warmer and frequently murkier water, use never-ending UV loops with moderate flow-rate modifications. To ensure that larvae are not threatened by zooplankton and bacterial infections, shrimp hatcheries rely on high-dose UV and ultrafine mechanical filtration (FAO, 2020). Twin UV sterilizers are commonly used in marine finfish farms to reduce parasite pressure during the initial stages of production. One of the most effective engineering-based parasite control systems in contemporary aquaculture is the interaction between the optimization of flowrates and UV sterilization. UV neutralizes pathogens prior to their being introduced into the culture units and optimized flow eliminates internally produced infective stages before they can achieve their life cycles. The dual model prevents parasite populations to create self-sustaining cycles and increases survival, feed efficiency, and long-term biosecurity (González et al., 2023).
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.

Shandong Wolize Biotechnology, with 15 years of experience, ISO/CE certifications and university partnerships, designs and delivers turnkey RAS, high-density flow-through and aquaponic systems. Our equipment operates in 47 countries, powering 22 large-scale projects over 3,000 m³ each. We offer design, installation, training and lifelong support, helping farmers triple yield, cut costs 30 % and meet ASC/BAP standards. The Recirculating Aquaculture System (RAS) is a modern aquaculture technology designed to provide a stable and suitable growth environment for aquatic organisms through efficient water treatment and resource recycling. This system is widely applied in various types of aquaculture, including fish, shrimp, and crab farming, and boasts significant environmental, economic, and production advantages.
Market demand provides a solid guarantee of returns. Water resources are scarce in Saudi Arabia and the entire Gulf region, and the catch of marine products is limited, making over 80% of the local aquatic products dependent on imports. Tilapia and catfish, due to their fast growth, strong disease resistance, and good meat quality, are highly favored sources of protein. Localized farming not only shortens the long import chain, ensuring the freshness of the products, but also offers significant price competitiveness. This means that every fish produced by the farm can quickly enter the market and be converted into real profits. The conclusion is obvious: In Saudi Arabia, the galvanized sheet fish pond farming project perfectly aligns with the “Saudi Vision 2030” strategy on food security and economic diversification. With its outstanding product advantages, it has transformed the originally unfavorable natural environment into a controllable and efficient production system, and then connected with the huge and urgently needed local market. Eventually, it achieved a value leap from “a drop of water” to “a bucket of gold”, composing a touching “desert fish song” for investors.
