The laminar water flow is slow and facilitates sedimentation, thus the eggs of parasites, protozoa, or larvae settle on the surfaces of the pipes. Such deposits create reservoirs that inject infective content into the system on a regular basis. Conversely, turbulent water flow, which is normally attained when Reynolds numbers are greater than four thousand, suspends particulate material long enough to undergo mechanical filtration and sterilization processes (Li et al., 2023). The turbulent conditions are often created by engineers in the sections of the hydraulic line to prevent the destruction of fish species that are sensitive to turbulent water, including tilapia, catfish, and Pangasius (FAO, 2020).Species-specific hydrodynamic methodology is used so that the fish are subjected to suitable flow conditions without interfering with the removal of parasites.

Modern intensive systems, such as recirculating aquaculture systems (RAS) and biofloc technology, minimize environmental impact by reducing waste and water usage, addressing concerns about pollution. Economically, the sector creates jobs across the value chain – from farming and feed production to processing and distribution – empowering smallholder farmers and rural communities. For example, projects like the Promoting Sustainable Cage Aquaculture in West Africa (ProSCAWA) have enhanced livelihoods by building capacity in sustainable intensive practices, linking farmers to markets and knowledge transfer partnerships. In conclusion, intensive aquaculture is not merely an agricultural practice but a strategic imperative for West Africa. It directly addresses the region’s urgent market demand for seafood, leverages resource efficiency and economic empowerment, and paves the way for a sustainable, food-secure future.

Stabilization of a recirculating aquaculture system (RAS) as a zero-outbreak system has become a fundamental objective in modern aquaculture systems engineering, especially in a high stocking rate and low water exchange rate intensive commercial production system where microbial growth conditions are optimal. As aquaculture systems expand at a global level, maintaining water quality, stabilizing microbial populations, and eliminating pressure of pathogens inside highly controlled systems has become a key economic consideration and viability in the long term(Li et al., 2023). Zero-outbreak facility is the one that can maintain the well-being of fish and the environmental balance with the absence of disease incidents that interrupt the cycles of production and cause a high level of mortality. This stability cannot be accomplished through mere water exchange but rather a rigorous water treatment scheme that is scientifically based. The dual ozone biofilter method is one of the most effective methods employed in modern aquaculture and it is a synergistic process comprising of both advanced oxidation and biological nitrification to ensure the water quality, prevent pathogens, and achieve consistent environmental conditions, which is vital to the success of long-term systems (Preena et al., 2021).

Outlook: A Blueprint for the Future of Flow-Through Aquaculture Systems – As an important model of modern aquaculture, flow-through aquaculture systems have achieved remarkable success, but they still face some challenges and contain many opportunities in their future development. From a challenges perspective, cost is a major obstacle to the further promotion of flow-through aquaculture systems. Building a complete flow-through aquaculture system requires a significant initial investment in equipment purchase, site construction, and technology acquisition. During operation, equipment maintenance, energy consumption, and technology upgrades also incur ongoing costs. This poses a considerable burden for small-scale farmers or aquaculture enterprises in economically underdeveloped areas, limiting the widespread adoption of flow-through aquaculture systems.

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.

Ozone effects on the ecology of microbes are not confined to the inhibition of pathogenicity. Although ozone is a more effective method to eliminate the concentrations of harmful microorganisms, over-oxidation can destroy the positive microbial communities involved in degrading organic matter and maintaining biofilter stability. Under extreme oxidation conditions some microbial strains are ozone resistant and therefore may grow out of proportion, changing ecological equilibrium undesirably. To prevent these imbalances, effective RAS operators use moderate, managed doses of ozone that focus on reliability in the quality of water and not the aggressive treatment of water (Botondi et al., 2023). This is where the lightweight flow water system comes in. It offers the balance between the high-end control of RAS and the simple management of traditional flowing systems. The result is a customized, low-cost solution that fits the needs and budgets of smaller farms without compromising on performance.
