RO Systems for Marine Aquaculture: 2025 Hatchery Optimization Guide
Why Aquaculture Needs Precise Water Control?
• Salinity Management: Maintain optimal 10-35ppt levels for different growth stages
• Pathogen Prevention: Remove 99.7% bacteria/viruses (NOAA 2023 study)
• Heavy Metal Removal: Reduce Cu²⁺/Pb²⁺ to <0.01ppm (critical for larval survival)
• Cost Savings: 40% lower than traditional seawater transport (FAO data)
Industry Impact: Norwegian salmon farms achieve 92% survival rate with RO-treated water vs 68% with raw seawater
3 Key RO Applications in Marine Farming
1. Hatchery Water Preparation
• Target Parameters:
Salinity: 20±1ppt (adjustable)
TDS: <100ppm
Turbidity: <0.1NTU
• Benefits:
30% faster egg hatching
Reduced deformities in fry
2. Disease Control in Shrimp Farms
• Removes:
WSSV carriers (99.4% reduction)
Vibrio bacteria (WHO 2023 standard)
• Case Study:
Thai shrimp farm increased harvest from 12 to 18 tons/ha after installing RO
3. Broodstock Conditioning
• Custom Ionic Profiles:
Ca²⁺: 400-450ppm (shellfish)
K⁺: 300-350ppm (finfish)
• Result: 22% more viable eggs (Skretting research)
