Varicon Aqua Showcases HDRS™: Smart Rotifer Production for Hatcheries & Labs
Rotifers production has been a source of daily trepidation ever since large scale commercial hatcheries have been in operation anywhere in the world. With more than 35 years of experience in marine hatchery operations in both Europe and Asia we know that all too well and that is why we have designed these systems to deliver reliable and efficient production of rotifers. The High-Density Rotifer System (HDRS™) is an advanced solution for automated rotifer cultivation, suitable for both laboratory-scale research and commercial hatchery operations. Engineered with industrial-grade components, the HDRS™ ensures reliable, continuous production while maintaining optimal culture conditions for rotifers. Designed with flexibility in mind, the system can be customised in terms of tank sizes, numbers, and control modules, allowing it to adapt to a wide variety of applications, floor plans and facility requirements.

The HDRS™ features automated control of feeding, temperature, oxygen, pH, and metabolite levels, all monitored via high-precision sensors, dosing pumps, and flow meters. The culture system utilises a feedback mechanism to optimise rotifer density, achieving turnover rates of up to 40% per day with densities of 3,000 rotifers/ml. This supports a daily production of approximately 1.2 billion rotifers from a single 1 m³ culture tank. Harvested rotifers are transferred to a separate receiver tank, minimising handling and ensuring that the main culture remains undisturbed. To support the rotifer production we have designed and manufactured a Rotifer Concentrator (C-R), optimised for high-density rotifer harvesting and concentration. It shares the same durable build quality as the HDRS™ and features a 55 µm mesh and dual air curtains for effective filtration and ensuring consistent harvesting efficiency while protecting the rotifers from damage during the harvesting process.
Remote management is a key feature of the HDRS™, offering seamless monitoring and control via an inbuilt data acquisition and Human-Machine Interface (HMI). The system can be accessed from laptops, desktops, tablets, or smartphones, providing flexibility and ease of operation from anywhere. Additionally, its robust design supports the use of multiple feed substrates, including concentrated algae pastes and formulated diets, to accommodate a range of feeding protocols.
With its highly adaptable design and Varicon Aqua’s extensive after-sales support, the HDRS™ is a dependable choice for efficient rotifer production. Whether you’re developing feed products, scaling hatchery operations, or conducting research, the HDRS™ delivers consistent performance and unparalleled flexibility.
