High performance aquaculture equipment factory: Galvanised metal tarpaulin ponds also excel in aquaculture management. The pond structure typically incorporates transparent or semi-transparent tarpaulin coverings, enabling direct observation of rainbow trout growth, feeding behaviour, and water transparency. Integrated with modern water quality monitoring equipment, these structures enable real-time, precise control of critical parameters such as dissolved oxygen levels, water temperature, and pH. This facilitates meticulous feeding and management practices, significantly enhancing feed conversion rates and fish survival rates. As illustrated, fish farmers can conveniently conduct daily feeding and inspections, substantially improving management efficiency.

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.

Ozone alone cannot maintain a stable RAS environment. Fish release ammonia continuously through their gills and metabolic waste, and even low concentration of ammonia impairs gill function, suppress appetite and inhibit growth. Due to this fact, biological filtration is the second key pillar of the dual-treatment approach. In the biofilter, Nitrosomonas, Nitrobacter and Nitrospira are specific nitrifying bacteria that will turn ammonia to nitrite and subsequently to nitrate via the nitrification process (Oshiki et al., 2022). This bio-chemical conversion is necessary in preserving a safe environment in high-density aquaculture plants. Due to ozone being sensitive to these bacteria, physical separation between ozone contact and biological filtration must be maintained during system design. In contemporary RAS, ozone is sprayed into a separate chamber where it combines with water then flows through a degassing unit that removes all the remaining ozone. This step is only done after which treated water can be admitted into the biological filtration process(Xiao et al., 2019).

Conserving resources and ensuring sustainability – In today’s increasingly water-scarce world, the sustainability advantages of flow-through aquaculture systems are becoming increasingly apparent. It enables the recycling of water resources, purifying wastewater generated during the aquaculture process through a series of advanced water treatment technologies to meet reuse standards, thus significantly reducing the demand for fresh water. Statistics show that flow-through aquaculture systems can achieve a water recycling rate of over 90%, requiring only minor replenishment for losses due to evaporation and sewage discharge. Furthermore, flow-through aquaculture systems reduce reliance on land, enabling high-density farming within limited space and improving land use efficiency. This green and environmentally friendly aquaculture method protects the ecological environment and aligns with the concept of sustainable development, laying a solid foundation for the long-term stable development of fisheries.

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.
