Coupled vs. Decoupled
Major Drawbacks:
Growth conditions (temperature, pH, etc.) for both plants and fish are not optimal.
Lower yields compared to stand-alone hydroponic and aquaculture systems.
Fish sludge (poop) is not used => nutrient loss!
One-Loop Systems

Advantages:
Optimal conditions for fish and plant
Remineralization of fish poop in anaerobic reactors; i.e. creation of bio fertilizers for the plants
Main water loss only via evapotranspiration; i.e. ETc dependency
Increased Yields
Control the concentration of the hydroponic nutrient solution.
Disadvantage:
Measurement and Control
Complexity (HRM!)
