Iron and Potassium Fertilization Improve Rocket Growth without Affecting Tilapia Growth and Histomorphology Characteristics in Aquaponics

Aquaponics provides an alternative opportunity for the combined production of fish and plants. Most essential nutrients required optimal plant growth can be supplied from feed, except K Fe. These are usually inadequate in feed. In this study, red tilapia rocket plants were co-cultivated aquaponics system along with extra addition Fish growth, morpho-anatomical characteristics, Fe loading on gills studied. Plant parameters also determined. The slightly improved produced fresh biomass per unit area had no impact survival. No severe histological alterations gills, liver, midgut detected. EDX analysis showed that led to enrichment specific ion but effects accumulation found other aspects
