Longfian On-Site Oxygen Generators: Powering Profitable & Sustainable Aquaculture
As global seafood demand surges and wild fisheries decline, aquaculture has become the backbone of sustainable protein supply. For fish and shrimp farms - especially delicate white shrimp larvae hatcheries - stable dissolved oxygen (DO) is critical to survival, growth, and profit. Longfian on-site oxygen generators provide reliable, high-purity oxygen on demand, replacing costly cylinders and unlocking higher yields for modern aquaculture.
How It Works
Longfian PSA systems produce 93% pure oxygen from ambient air. The oxygen is injected into circulating water via venturi nozzles, then evenly distributed to maintain ideal DO levels (5–6 ppm / 70% saturation). Systems can be auto-controlled with DO probes for stable, hands-off operation.
Key Benefits for Farmers
24/7 reliable oxygen supply - no delivery delays or shortages
Low maintenance & plug-and-play - only routine filter and compressor checks
Dramatic cost savings - eliminate recurring cylinder and bulk oxygen fees
Higher survival & faster growth - less stress, disease, and mortality
Better water quality - uniform DO, reduced nitrogen, and cleaner environment
Higher stocking density & premium harvest quality
Real Client Case: White Shrimp Larvae Hatchery
A leading Ecuadorian white shrimp larvae hatchery installed a full Longfian oxygen system to improve post-larvae survival.
Results achieved:
Larval survival rate increased from 55% to 92%
Monthly larvae production rose by 48%
Larvae reached saleable size 3 days faster
Eliminated monthly cylinder costs, with fast projected ROI
For a Growing Global Market
With protein demand set to rise 52% in the next 30 years, sustainable, high-density aquaculture is essential. Longfian oxygen systems let farmers scale responsibly, boost profits, and produce healthier seafood worldwide.
