Top fish farming supplies factory: 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.

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.
The significant increase in unit output efficiency greatly enhances economic benefits. Traditional pond farming has a low density, with an average yield of only a few hundred kilograms per mu, and is limited by land area in terms of large-scale expansion. RAS systems can increase space utilization through three-dimensional farming and multi-layer layouts, with a farming density 5 to 10 times higher than that of ponds, and an equivalent yield of several thousand kilograms per mu. At the same time, precise feeding and stable environmental conditions reduce feed waste and disease losses, increasing the feed conversion rate by 15% to 25% compared to traditional methods, significantly reducing the production cost per unit product. Export potential will expand as West African producers meet global standards for quality and sustainability, tapping into European and global markets hungry for responsibly sourced seafood.
Galvanised metal tarpaulin ponds also excel in aquaculture management. The pond structure typically incorporates transparent or semi-transparent tarpaulin coverings, enabling direct observation of rainbow trout growth, feeding behaviour, and water transparency. Integrated with modern water quality monitoring equipment, these structures enable real-time, precise control of critical parameters such as dissolved oxygen levels, water temperature, and pH. This facilitates meticulous feeding and management practices, significantly enhancing feed conversion rates and fish survival rates. As illustrated, fish farmers can conveniently conduct daily feeding and inspections, substantially improving management efficiency.
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. Read many more information at https://www.wolize.com/.
