High performance fish farming supplies manufacturer: Controlling parasites in flowing aquaculture is one of the most long-standing problems of producers of the global community, especially in the systems whose water flow is continuous, i.e., flow-through, semi-recirculating and hybrid RAS aquaculture systems design (Power et al., 2025). This unceasing flow of water is not only vital in oxygenation but also in the removal of waste, which also provides effective routes through which parasites spread to various tanks and production lines. Many parasites possess mobile infective stages adapted specifically to aquatic hydrodynamics, allowing them to exploit water currents as transport mechanisms to reach new hosts (Mouritsen, 2025). As aquaculture becomes increasingly industrialized, the consequences of even moderate parasitic infestations have grown more severe because stocking densities are higher, production schedules are tighter, and biological stress tolerance among cultured species can be easily exceeded (Madsen & Stauffer, 2024). These pressures have made engineering-based parasite control a necessity rather than an optional management strategy. Among the technology-driven solutions available, the combined use of flow-rate optimization and ultraviolet sterilization has emerged as one of the most effective ways to interrupt transmission cycles and stabilize health performance in flowing aquaculture environments (Li et al., 2023).
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.
Recirculating aquaculture systems recycle over 95 percent of water contained in culture tanks, mechanical filters and treatment chambers. Although this will decrease the environmental discharge and enhance sustainability, it will also cause the concentration of dissolved organic carbon, suspended solids, mucus, fecal particles, uneaten feed, and diverse microbial communities (MAT, 2025). When such compounds build up beyond the optimum levels, they limit the penetration of light, elevate biochemical oxygen requirements, promote the growth of detrimental bacteria and add stress to the fish. Stress suppresses the immune system, destroys feeding performance, and predisposes Vibrio, Aeromonas, Flavobacterium, parasites, viruses, and other opportunistic pathogens. Because of these reasons, high performance RAS design is focused on effective water treatment mechanisms which can constantly regulate organic load and microbial activity (Fossmark et al., 2020).
Flow-through aquaculture systems will undoubtedly play a more vital role in the future development of the aquaculture industry. They will not only meet the growing demand for high-quality aquatic products but also drive aquaculture towards modernization, intelligence, and green development, achieving a win-win situation in terms of economic, social, and ecological benefits. It is believed that with the joint efforts of all parties, the future of flow-through aquaculture systems will be full of unlimited possibilities, making a greater contribution to the sustainable development of global fisheries. RAS (Recirculating Aquaculture System), as a core technology in modern aquaculture, has multiple advantages over traditional pond farming due to its efficient resource utilization and precise environmental control. It has become a key direction for the transformation and upgrading of the aquaculture industry. Its core advantages are mainly reflected in four dimensions: resource utilization, farming efficiency, environmental protection and safety, and risk resistance.

Our team always adheres to the concept of “scientific farming, ecological priority”, and closely integrates the cutting-edge scientific research results with the actual farming needs. And we have constructed a set of scientific management system for the whole process to ensure the quality and safety of aquaculture products. At the same time, our team is actively engaged in the exploration and promotion of ecological farming mode, through the construction of the “farming – wastewater treatment – planting” cycle system, to achieve the efficient use of resources and friendly development of the environment, and won the industry inside and outside the widely recognized. We always adhere to the principle of “integrity-based, mutual benefit and win-win”, and have established a stable cooperative relationship with global partners, maintaining a good record of zero complaints for many years, and become a reliable partner in the field of aquaculture foreign trade!
To ensure the success of the dual ozone-biofilter system, it is important to maintain the right operation parameters. The values of oxidation-reduction potential in the ozone contact chamber are normally 275 to 320 millivolts (mV). This spectrum aids in efficient reduction of organic matter without generating any undesirable reaction byproducts (Davidson et al., 2021). Before the ozone unit, mechanical drum filters of sixty to one hundred microns in size are used to remove large, suspended solids to enhance ozone efficiency by decreasing the organic load. Optimal values of dissolved organic carbon are four milligrams per liter because beyond this level, the water fails to be clear and promotes the growth of microbes. The concentration of dissolved oxygen below the ozone chamber is usually more than nine milligrams per liter since ozone decomposes naturally to produce oxygen. Having high dissolved oxygen levels greatly improves fish metabolism as well as the rate of nitrification. Most importantly, the amount of residual ozone entering the biofilter should also be zero, this is achieved through constant monitoring to ensure that the nitrifying bacteria is not damaged.
