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.
West Africa stands at a critical juncture where rising food security needs, demographic growth, and shifting consumer preferences are driving an urgent demand for sustainable seafood production. Intensive aquaculture – characterized by high-density cultivation in controlled environments – has emerged as a transformative solution to address the region’s seafood supply challenges while unlocking significant economic and nutritional opportunities. As wild fish stocks face overexploitation and traditional fishing struggles to keep pace with demand, intensive aquaculture offers a path to resilience, productivity, and prosperity for West African nations.
Flow-rate optimization is an interruption to this dynamic, which causes the hydraulic retention time in each tank or raceway to change. Hydraulic retention time is the time a particle stays in a particular unit before it is forced out (Fan et al., 2023). The shortening of this retention time will allow farms to physically eliminate stages of infective parasites before attaching to fish. The research on monogenean larvae reveals that, they are the most perilous during the initial two hours of their hatching and the infectivity reduces drastically after four to eight hours (Hoai, 2020). In juvenile salmonid or marine finfish systems with retention times in the farms of between thirty and fifty minutes they significantly decrease the likelihood of encountering a host by the larvae. It is an engineering-based solution that is not based on chemicals or biological remedies but rather relies on the velocity of water to exceed the pathogen biological window of infectivity (Morro et al., 2022). When handling highly parasite sensitive species like Atlantic salmon, rainbow trout, cobia, and sea bass, flow-rate manipulation is particularly of particular concern.
Flow-rate optimization involves eliminating parasites prior to infection whereas ultraviolet sterilization ensures that they do not even enter the system. The UV-C light, usually with the wavelength of 254 nm, alters and breaks the nucleic acid in microorganisms, inhibiting the replication of a species(González et al., 2023). Properly used, UV-C destroys more than 99 percent of free-moving parasite larvae, protozoan stages, zooplankton, as well as bacterial pathogens. Research has shown that doses of 30 to 120 mJ/cm² are neutral to a broad spectrum of aquaculture parasites (Fernández-Boo et al., 2021). Sensitive organisms, like Ichthyophthirius tomites, can be activated by low-levels as low as 25 mJ of energy, and more resistant organisms such as some marine protozoans such as Amyluodinium ocellatum could survive as many as 105 mJ (RK2, 2025). UV sterilization then appears as a necessary preventative that will stop parasitic and microbial pollution in flowing aquaculture systems.
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.
