Effects of Phosphate-Enriched Nutrient in the Polyculture of Nile Tilapia and Freshwater Prawn in an Aquaponic System

Aquaponic systems are made up of hydroponic beds and recycled aquaculture systems. The significant elements that determine how effectively an aquaponic system operates the nitrogen cycle (nitrification) phosphorus (phosphate). Because some research indicates aquaponics primarily deficient in phosphorus, phosphate-enriched nutrients were added to raise levels. During eight-week experimental period, effects water quality parameters microbiology, animal plant growth performance, chlorophyll compounds lettuce, bacterial community analyzed. Phosphate concentration (1.604 ± 1.933 mg L?1) ammonia-oxidizing bacteria (AOB) (1.19 × 102 1.30 CFU mL?1) give positive reactions nutrients. However, prawn survival rate (17.00 0.63%) showed a significantly negative response nutrition modification containing phosphate, percentage pathogens became more dominant (pathogen 40.51%; N_bacteria 35.05%; probiotics 24.44%). This study shows adding phosphate increases levels changes microbial species performance.
