Fish farming supplies provider right now: 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.

Exploring the unique advantages of flow-through aquaculture systems – High output and high efficiency. Flow-through aquaculture systems are like a meticulously crafted “high-speed growth paradise” for fish. The continuous flow of water not only brings ample oxygen but also provides the fish with abundant food resources. In this superior environment, the fish live like they’re in a vibrant “gym,” their metabolism accelerates, and their growth rate increases significantly. Compared to traditional aquaculture methods, flow-through aquaculture systems can significantly shorten the fish’s growth cycle and greatly increase yields. In some high-density flow-through aquaculture practices, yields can reach over 200 kilograms per square meter, an increase of about 40% compared to conventional fishponds. This means that farmers can harvest more fish in the same aquaculture area, thus achieving higher economic benefits.
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.
Galvanised metal canvas ponds demonstrate clear advantages in terms of construction costs and flexibility. Compared to traditional concrete or earthen ponds, this structure is simple to install and highly modular, substantially reducing construction timeframes and lowering initial investment. In many complex topographical areas of Central Asia with constrained land resources, such as mountainous regions and semi-arid zones, these ponds can be flexibly deployed and rapidly brought into production, effectively alleviating the constraints imposed by land limitations on aquaculture. Moreover, their relocatable and easily expandable nature facilitates farmers’ ability to adjust production scale in response to market fluctuations.
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).
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.
