Good RAS Water-Saving Graphic

Here’s a great graphic folks can use to show the water savings of protein from fish in RAS vs other animal proteins.

This Graphic is from the Aquaponics Food Production Systems Handbook, a great FREE resource. Can be found here: Aquaponics Food Production Systems - Combined Aquaculture and Hydroponic Production Technologies for the Future | Simon Goddek | Springer


Nice picture, but not true unfortunately. 1kg wheat which is the least waterintensive ingredient of fishfood requires around 1500 liters of water to produce (double that for soybean, corn, rice). You need more than 1 kg of fishfood to produce 1 kg fish meat in RAS. So in general that value is much closer to chicken.
