How to start fish farming in just 10 easy steps

A system that feeds fish and plants

Aquaponics combines fish farming (aquaculture) and soil-free plant growing (hydroponics), recycling nutrient-rich water from fish tanks to feed plants, while plants, in turn, purify the water for the fish. The result? Up to 95% less water use and a fully organic system that thrives without synthetic chemicals or pesticides.

This article features insights from MJ Nunes of Sable Creek Farms, one of South Africa’s leading aquaponics pioneers, unpacking the science, strategy, and sustainability behind this closed-loop farming method.
