Live transport & high-density systems
Live seafood transport depends on constant oxygenation — mortality spikes the moment dissolved oxygen drops.
Our solution
Aeration hose can be cut to length and shaped to any tank, delivering fine bubbles with little air resistance — so a small blower keeps DO stable for hours.
- Hose cut to any length and bent to any shape
- Low energy input — a small blower serves the whole tank
- High oxygen transfer per unit of air
- Also supports high-density pond systems (≈80 kg fish/m³ reported)
Recommended system
Compact blower + aeration hose or tubes, sized to tank volume
Transport is the hardest aeration duty
In a hauling tank the water volume per kilogram of fish is small, the animals are stressed, and there is no photosynthesis to top the oxygen up. Mortality in live transport nearly always traces back to a fall in dissolved oxygen rather than to temperature. The system has to hold the level for the whole journey, including the standing periods at either end when nobody is watching the tank — which is the part that is easiest to under-design.
Why hose suits a transport tank
Aeration hose can be cut to length and bent into the footprint of whatever tank is on the vehicle, which rigid diffuser assemblies cannot. Because the hose offers little resistance to airflow, a small blower is enough to serve the whole tank; the practical limit on a truck is the power supply, not the air volume. Fine bubbles also mean a larger share of each litre of air dissolves rather than escaping at the surface, which matters when the blower is running from a battery.
Practical setup notes
Keep the diffuser low in the tank so the bubbles have the full depth to transfer in, and keep the return path clear so the rising column turns the water over instead of channelling through a single line. Allow headroom in the blower for the standing periods: stocking density in a transport tank is closer to a high-density farming system than to a pond, with reported densities of around 80 kg/m³, so an undersized air supply has very little margin.
The same equipment in high-density systems
The hose-and-compact-blower arrangement is not limited to vehicles. It is used in high-density tank systems and in pond situations where a rigid diffuser run will not fit — corners, odd-shaped basins, and retrofit jobs where the water cannot be drained. Because hose has low airflow resistance it can also be run in longer lengths than rigid pipe from the same blower, which is often what makes a compact installation possible at all.
