From Algae to Eel – Our Tube Technology

This is the tube system that started it all.
Originally developed for large‑scale algae cultivation (featured on CNN and multiple international news outlets), the same 35 cm diameter transparent tube with water‑driven sponge cleaning is now being adapted for eel farming.

What you see in the images and video:

Self‑propelled cleaning sponge (pushed by water flow)
Automatic docking and washing station
Proven in long‑duration algae production

Why this matters for eels:

The tube is the perfect size for juvenile to market‑size eels (up to 1 kg).
The cleaning system keeps walls clear – no biofilm, full visibility.
Recirculating design saves 90% water compared to flow‑through systems.
Eels thrive in narrow, current‑swept environments – exactly what this tube provides.

Why Anguilla Tube?

1. See your eels grow – without stress
Transparent walls let you observe feeding, behaviour, and health at any moment. No need to catch, net, or handle them – which means less stress and lower mortality.

2. Spot sickness early
Visual inspection allows you to detect diseases or parasites immediately – before they spread through the whole system.

3. Zero escapes
The tube is fully closed. Unlike open tanks or net pens, eels cannot jump out or slip through gaps.

4. Endless swimming – natural habitat
A gentle water current encourages eels to swim against the flow, just as they would in rivers or during migration. They can travel kilometres inside the tube – physically fit and naturally active.

5. Adjustable water flow
Control the current speed to match different growth stages – slower for juveniles, stronger for larger eels to build muscle.

6. Easy temperature adjustment
Integrated heating/cooling options keep water at the optimal temperature for eel growth year‑round.

7. Full water quality control

pH control – automatic dosing keeps pH stable.
Oxygen control – air or pure oxygen injection maintains high dissolved oxygen levels.
Filtration – mechanical and biological filters remove waste and ammonia.

8. Manual or automatic computerised control
Run the entire system manually, or let a computer manage flow, temperature, pH, oxygen, feeding, and cleaning. Remote monitoring via smartphone or PC is also possible.

9. Automatic feeding
Programmable feeders release the right amount of feed at set times – reducing labour and improving feed conversion.

10. Direct eels to another tube or holding zone
Integrated gate valves or diverters let you move eels without handling. Separate by size, harvest a portion, or isolate sick eels – all without stress.

11. Self‑cleaning – no labour
The water‑driven sponge travels the entire tube, scrubs away biofilm, and automatically docks in a washing station. Your job is watching, not scrubbing.

12. 90% less water
Fully recirculating system – filter, reuse, and save on heating, pumping, and water treatment.

13. Eel‑friendly dimensions
35 cm diameter is perfect for eels from juvenile to market size (up to ~1 kg). It mimics the narrow crevices eels love in nature.

14. Optional black sections
Add opaque tube segments where eels can hide and rest – giving them the best of both worlds: observation when you need it, shelter when they need it.

15. Space‑saving design
Stack tubes vertically or coil them in a small footprint. Turn a garage or warehouse into a high‑density eel farm.

16. Proven technology
The same tube and sponge system was featured on CNN and used successfully for large‑scale algae production. Now adapted for eels – with the inventor himself leading the way.
