This document discusses a decoupled aquaponics system where fish waste and nutrients can flow one-way from the fish system to the plant system for better nutrient usage. The key components needed are sumps, pumps to transport water from the fish tanks to the plant beds, auto-watering pots for the plants, and PE water lines. General information required includes annual production numbers, species selection, timeline, location details, water and power sources, buildings, and markets. The advantages are using fish waste to feed plants, independent system treatment, and potential PR benefits from a more sustainable RAS setup.

1. Decoupled Aquaponics
Option
Huy Tran

2. Applications/Advantages for
Decoupled
System
• Fish waste: From system or from backwash feed directly to plants
system
• Nutrients: can flow one way if need, better usage of aquaculture
discharges (cut PVC cost, no return lines)
• RAS discharges can be used to grow crops, PR for a more green RAS
• Treatment of Systems can be Independent

8. Needed
Components:
Sump/s
Pump (one 1/4Hp can
pump up 500m away and
up to 800 unites at 2
plants/unit)
Auto Watering Pots
PE water lines
