Aquaculture equipment factory today: 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.

By embracing innovation, fostering regional collaboration, and prioritizing environmentally responsible practices, West Africa can position itself as a leader in sustainable aquaculture – turning its water resources into a catalyst for economic growth, nutritional security, and resilient communities. The potential is clear: intensive aquaculture is set to transform West Africa’s food systems, one harvest at a time. In Central Asia, rainbow trout farming is gradually emerging as a significant aquaculture industry. Given that most nations in the region are landlocked with unevenly distributed water resources, traditional aquaculture models are often constrained by natural conditions and high construction and maintenance costs. In recent years, the land-based galvanised metal canvas pond model has gained traction, offering substantial technical and operational advantages for rainbow trout farming. This approach has emerged as a key pathway for advancing sustainable aquaculture development locally.

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).

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.

The Flowing Aquaculture System is a traditional and widely used aquaculture technology model that relies on naturally occurring or artificially constructed water flow environments. Its core feature is the provision of fresh water, sufficient dissolved oxygen, and natural food for aquacultured organisms through continuous water exchange, while simultaneously removing metabolic wastes to maintain the dynamic balance of the aquaculture environment. This system is applicable to both freshwater and marine aquaculture, and is particularly suitable for species with high requirements for water quality and dissolved oxygen. An investigation by experts organized by Xiuning County confirmed that over 3,000 ancient fishponds built in various eras within the county preserve the complete historical record of spring-fed fish farming from its inception to maturity.

Against the backdrop of a growing global population and increasingly strained wild fishery resources, aquaculture has become a key industry for ensuring protein supply security. However, traditional aquaculture models often come with environmental pressures, high consumption of land and water resources, and the risk of disease transmission. Within this global context, the African continent stands at a historic crossroads. It boasts vast coastlines and abundant water bodies, yet simultaneously faces severe challenges related to food security, water scarcity, and climate change. It is precisely within this complex scenario that a revolutionary technology known as Recirculating Aquaculture Systems (RAS) is quietly emerging in Africa, heralding a silent yet profound transformation for the continent’s aquaculture sector.
