Fish farming supplies supplier 2026: In the 1980s, with the initial development of biological filtration technology, land-based recirculating aquaculture systems (RAS) made significant progress. People gradually recognized the crucial role of microorganisms in water purification, and facilities such as biofilters began to be applied to aquaculture systems, more effectively removing harmful substances such as ammonia nitrogen from the water and improving the quality and stability of the aquaculture water. Simultaneously, automated control technology began to emerge in the aquaculture field. Some simple automated equipment, such as timed feeding devices and automatic control systems for aerators, were introduced, initially achieving automation in some aquaculture processes and reducing manual labor intensity. During this period, the variety of farmed species gradually increased. In addition to traditional commercial fish, some shrimp and shellfish also began to adopt RAS models, and the scale of aquaculture expanded, gradually forming a certain industrial scale in Europe and America.

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.
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.
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.
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).
A RAS Aquaculture System is a closed-loop setup that filters, cleans, and reuses water continuously. It helps farmers maintain stable water quality, reduce waste, and increase fish survival rates. In a traditional flow-through system, water enters from an external source, flows through tanks, and exits. In contrast, a RAS recycles up to 95% of its water, making it far more sustainable. However, RAS technology involves higher upfront costs, specialized components, and complex maintenance. For small farmers, this can be overwhelming. That’s why the lightweight flow water system – inspired by RAS principles – is quickly gaining traction worldwide. Why Small and Medium-Sized Farms Need a “Lightweight” Solution – Not every farm needs a full-scale industrial RAS setup. Small and medium farms usually focus on local markets, specialty species, or starter hatcheries. Their goal is often steady production, not mass volume.
