Automated Fingerling Nursery System: High Survival Rate & Cost Reduction
- Wastewater filtration and treatment system: When water flows out of all 20 culture troughs, it immediately enters a physical drum filter to separate heavy sediments. The water then flows into a sump pit and is pumped up into the first and second Moving Bed biological treatment tanks, respectively, to eliminate waste and ammonia.
- Disinfection and aeration process: The treated water flows back into the clean water tank, passing through an inverter-controlled pressure pump into an oxygen cone and through a UV sterilization system to disinfect the water before returning it to the culture troughs.
- Nano Bubble technology: All water fed into the system utilizes nano-sized bubble technology, which significantly increases the oxygen dissolution rate in the water, keeping it at a high level for a longer duration than usual.
Have you ever experienced it? You invest heavily in fish fry, caring for them meticulously, only for oxygen levels to drop around 3:00 AM or for ammonia levels to silently rise without you noticing. You wake up to find the entire pond of fish in shock and dead, suffering hundred-thousand-baht losses in a single night!
These problems are the nightmare of every aquaculture farmer. But today, there is a model farm that has completely solved this vulnerability by transforming into an "automatic recirculating water fish nursery system" controlled 24/7 by a smart farm system, resulting in a skyrocketing survival rate!
Want to know how this system works and why it guarantees true cost reduction and automated yield increases across the board?

Deep Dive into the Water Treatment and Recirculating Filter System
The engineering design of the water circulation system ensures that every drop of water recycled is clean, free of residual waste, and contains optimal oxygen levels for the daily growth of fish fry.
Intelligent control system, working for you 24 hours a day
Eliminate worries about manual labor and human error with a system truly designed for fish nursing.
- Independent Feeding and Water Flow Adjustment: Fully independent schedules can be set for all 20 troughs, supporting up to 15 feeding times per day and 5 water flow rate adjustments daily. The system measures using actual Flow Meters for precision without guesswork.
- Real-Time DO-Based Oxygen Control: The system triggers oxygen supplementation based on real-time measured DO values (rather than simple timer-based on/off schedules), complete with ultimate safety features. If the primary unit fails to meet the required threshold, the system automatically switches to activate a backup unit.
- 27-Point Sensor Network with Advanced Processing: Covers measurements for DO, temperature, pH, ammonia, ORP, and greenhouse gases. A key highlight is that the system measures critical parameters in triplicate and calculates the average. If any sensor reads an anomalous value, the system immediately excludes it from the calculation to prevent errors.
- Easy Control via Touchscreen: Centralizes all controls in a single interface, displaying a comprehensive overview of the entire facility. It operates stably even without an internet connection at the farm and records historical data for every parameter, enabling farmers to analyze and leverage the data further.
Behind the Innovation: Combining the Power of PLC LicOS and AI
The intelligence of this system does not stem from sensors alone; it is the result of design and development in collaboration with AI.
The main brain of the system uses PLC LicOS, with the operating logic programmed via CODESYS, while the user interface (UI) is developed on a Windows-based system. Our primary intention is to demonstrate that PLC LicOS technology can work perfectly with AI throughout the entire process—from assisting in writing the logic to calculating values on the display screen.
Summary
The automatic recirculating water fish nursery system is not just a new piece of equipment on the farm; it is an essential "key assistant" that works for you 24 hours a day. It helps reduce risks from uncontrollable environmental conditions, lowers labor and water costs, and boosts the survival rate of fish fry to ensure strong, fast-growing yields and sustainable profits.
