Aquaponics have related food and nutrition security benefit that are important for this country (South Africa). The aim of this study was to apply aquaponics decision-making tool to provide potential aquaponics production data and information for South Africa. This study was designed as 2X3X3 factorial study giving 18 interactions. Because aquaponics are the production of fish and crops concurrently, yield production had two levels-fish and crop, fish stocking density had three levels-low, optimum and higher and aquaponics scale of production had 3 levels-hobby, subsistence and commercial scale. The summary of data of aquaponics variables from the literature was used as optimum level, lower and higher levels were based on experimental design. Yield production (kg) of both fish and plants increased significantly (p Key words: Fish stocking density, Yield production, Fish feed, Planting area, INTRODUCTION Poverty and inequalities have risen with the advent of Covid-19 across the world, particularly in South Africa. Aquaponics is the innovative production of fish and crops concurrently in one [...]
