Aquaculture equipment manufacturer today: Technological stability is also a key concern. Although current flow-through aquaculture technology is relatively mature, it can still be affected by various factors in practical applications, such as equipment failure, sudden changes in water quality, and climate change. Problems with the technical system can lead to a deterioration of the aquaculture environment, hindered fish growth, and even large-scale disease and mortality, causing significant losses to fish farmers. Furthermore, as people’s demands for the quality and safety of aquatic products increase, flow-through aquaculture systems face new challenges in ensuring the quality and safety of aquatic products. Continuous optimization of aquaculture processes, strengthened management of feed and medication use, and improved quality testing and traceability systems are necessary.
To get to know this integrated approach, the first step is to see the behavior of parasites in flowing water. Almost all parasites that cause severe production losses in aquaculture, including Ichthyophthirius multifiliis, Trichodina, Amyluodinium and monogeneans of genera such as Dactylogyrus and Gyrodactylus, have free-swimming larvae or trophont stages that can move temporarily on their own (Buchmann, 2022). These infective stages depend on hydrodynamic forces to spread between tanks. In a connected water system, tomites, theronts and oncomiracidia are blown downstream by the currents and are transported because of sharing drainage lines, distribution manifolds, head tanks, and intermediate waterways, significantly amplifying the transmission potential (FAO, 2024). As they drift, they encounter new hosts at a much higher frequency than they would in stagnant water, allowing populations to expand even when clinical symptoms remain undetectable. Research from freshwater and marine aquaculture systems consistently shows that flowing water accelerates the spread of nearly all protozoan, monogenean, and crustacean parasites (Buchmann, 2022). Without intervention, parasites rapidly establish cyclical reinfection loops, increasing the likelihood of chronic gill irritation, reduced feed uptake, compromised immunity, and elevated mortality.

The synergy of ozone treatment and biological filtration scientists is supported by scientific studies. Comparative studies on the water entering biofilters with ozone and non-ozone water indicate that ozone water enhances the efficacy of nitrification by decreasing the heterotrophic fight over oxygen and surface area. Ozonated water also causes a lower biofouling, more stable nitrifying biomass and faster recovery following stress events like feeding spikes or temperature changes in biofilters fed ozonated water. With effective functioning of biofilters, levels of ammonia and nitrite are maintained at a low and constant level, lowering the stress levels in fish, and lowering the chances of disease outbreaks. The basis of a zero-outbreak RAS strategy is this synergy whereby the ozone clears the water and the pathogens, and the biofilter keeps the nitrogen steady (Pumkaew et al., 2021).
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.
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.

Flow-through aquaculture systems are not a modern invention; their history is long and rich. In China, the history of spring-fed fish farming in Xiuning County can be traced back to the Tang and Song Dynasties. The area boasts abundant mountains, dense forests, crisscrossing rivers, numerous streams and ponds, and pristine springs, providing ideal natural conditions. Villagers fully utilized the rich water and forage resources, as well as the unique native fish species, to construct fishponds and ponds along mountain streams, in village lanes, around houses, and within courtyards. They introduced spring water for fish farming, forming an agricultural cultural heritage system based on flow-through fish farming, coupled with agricultural and fishery ecological farming. This method of fish farming has been passed down for thousands of years and continues to thrive today.
