Pond Engineering & Standards:
Thuan Thanh’s farming system is systematically designed and master-planned to meet strict technical standards, creating the perfect growth environment for our shrimp:
Optimal Scale and Design:
Flexible pond areas ranging from 2,000 to 5,000 m² with a standard depth of 1.5 – 1.8 m (maintaining a stable water level of 1.2 – 1.5 m). Equipped with separate intake and drainage gates. The pond bottom slopes towards the drainage gate (which is 20 – 30 cm lower than the pond bottom) to ensure thorough waste discharge.
Pond embankments are solidly reinforced, leak-proof, constructed at least 0.3 – 0.5 m higher than the maximum tide level, and wide enough to accommodate the mechanized transport of feed and equipment.
Strict Soil Management:
Farming areas are adaptable to various bottom types (sand, muddy sand, or gravelly sand) with excellent anti-leakage properties.
For bottoms with high alum content, rich organic matter, or newly converted land, we proactively apply specialized bottom-reinforcement materials. This completely prevents the generation of toxic gases (NH3, H2S) and controls suspended organic matter.
Water Quality Control:
The intake water source is proactively managed to ensure it is absolutely pollution-free. Physicochemical parameters are maintained at ideal levels: Water pH (7.5 – 8.5), Bottom pH (> 5.5), Dissolved Oxygen (4 – 9 mg/l), and Salinity (5 – 30‰).
Circular Ecosystem System:
Ponds are scientifically laid out between the intake and drainage canals (with the pond bottom at least 30 cm higher than the drainage canal bottom).
We apply a closed-loop circulation model integrated with seaweed cultivation areas using a circulation pump system, facilitating natural water filtration and protecting the ecological environment.
To meet the rigorous international inspection standards regarding chemical residues, Thuan Thanh strictly implements a clean, 100% antibiotic-free shrimp farming model. The key to this success lies in our multi-stage water treatment system, ensuring that all intake water is completely sterile, biosecure, and optimal for shrimp seeds.
Our treatment process is strictly operated through 4 stages:
Stage 1: Settling & Mechanical Filtration
Source water is directed into settling ponds and treated with Potassium Permanganate and PAC (safe, industry-approved flocculants that are completely harmless to consumers). A multi-layer screen system maximizes the removal of suspended solids and impurities before the water moves to the next phase.
Stage 2: Intensive Disinfection
Continuous Environmental Monitoring: Our engineering team conducts daily measurements and tracking of water quality parameters, with a special focus on toxic gases and mineral levels. Every minor fluctuation is meticulously recorded to ensure timely intervention and adjustment. Commitment to the “Antibiotic-Free” Model: Completely eliminating drugs and antibiotics from the farming process requires rigorous standards from day one. We establish a solid defense line through the absolute control of shrimp seed quality, water purity, and feed nutrition.
Accompanying Local Farmers:
In line with our mission to share sustainable values, Thuan Thanh advises partnering farmers who have not yet equipped their ponds with automatic systems to regularly check feeding trays (“nhá”) after each meal. Evaluating residual feed via these trays, combined with daily monitoring of water quality fluctuations, remains a highly effective manual method for farmers to promptly balance feed portions and maintain a healthy pond environment.
Stage 3: Natural Outgassing (Dechlorination)
The treated water is held in a designated resting pond, allowing all residual Chlorine to evaporate naturally. This crucial step ensures the water retains absolutely no chemical residues that could affect the shrimp’s health.
Stage 4: Microbial Inoculation & Ready-to-Stock
Once the Chlorine has completely dissipated, the water is pumped into the “Ready Pond” (the main farming pond). Here, we inoculate the water with beneficial probiotics to create a perfectly balanced, nutrient-rich ecological environment prior to stocking the shrimp seeds.
At Thuan Thanh, feeding and environmental management are highly technologized and strictly controlled to ensure uniform shrimp growth, robust health, and optimized production costs:
Automated Feeding System:
We fully operate automatic, timer-controlled feeding machines across our floating ponds. This technology enables us to precisely quantify and control the daily feed intake. Consequently, we can proactively adjust the feed volume based on the shrimp’s actual consumption, optimizing costs while completely eliminating the risk of water pollution caused by excess feed.
