Excellent water quality, safeguarding health – High-quality water is crucial for the healthy growth of fish, and flow-through aquaculture systems have a natural advantage in this regard. Flowing water acts like a diligent “cleaner,” promptly carrying away fish waste and uneaten feed, greatly reducing the risk of water pollution. Compared to traditional pond aquaculture, flow-through aquaculture systems offer more stable water quality, higher dissolved oxygen levels, and lower concentrations of harmful substances such as ammonia nitrogen and nitrite. This superior water environment not only reduces the likelihood of fish diseases and the need for medication but also aligns with the fish’s natural swimming instincts, ensuring their vitality and resulting in healthier, more delicious, and more competitive fish in the market.

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.

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.

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.
