Fish farming supplies factory 2026: 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.
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.
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).
In the early 21st century, with the rapid development of materials science, new corrosion-resistant, high-strength, and relatively low-cost materials, such as PVC and PE, were widely used in aquaculture facilities and piping systems, greatly improving the durability and stability of these systems. Simultaneously, significant breakthroughs were made in water quality monitoring technology, with the emergence of various high-precision sensors capable of real-time and accurate monitoring of key parameters in aquaculture water, such as temperature, dissolved oxygen, pH, and ammonia nitrogen. Based on this monitoring data, automated control systems became more intelligent, automatically adjusting equipment operation according to changes in water quality, achieving precise control of the aquaculture environment. Furthermore, in the field of aquaculture nutrition and feed technology, in-depth research was conducted on the nutritional needs of different aquaculture species at different growth stages, leading to the development of more precise feed formulations, improving feed utilization, and reducing environmental pollution. During this period, land-based recirculating aquaculture systems (RAS) developed rapidly globally, with Asia, South America, and other regions beginning to vigorously promote and apply this aquaculture model, resulting in a qualitative leap in both scale and technological level.

We combine generations of aquaculture expertise, with the latest,most advanced RAS (Recirculating Aquaculture Systems)technology, to create industrial, safe and sustainable aquaculture solutions for the local production of fish and seafood. Our products are sold well in 47 countries and regions. We have built 22 large-scale aquaculture projects with a water volume of 3,000 cubic meters. Our farmed fish are grown in 112 countries and regions. The factory is located in a standardized ecological aquaculture base, covering a number of categories of aquaculture areas, equipped with industry-leading intelligent aquaculture systems. Through the sensor real-time monitoring of water quality, water temperature, oxygen content and other key data, to achieve accurate feeding and environmental control, to ensure that each tail of aquatic products in the most suitable conditions to grow, from the source to ensure the high quality and stability of the product.
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.
