Comparative analysis reveals nutrient dynamics in three aquaponic systems with tilapia and crops, highlighting the necessity of careful monitoring for optimal symbiosis.
The effects of nutrient flows on tilapia fish (Oreochromis niloticus) and plant crops in three model aquaponic systems (deep water culture system, nutrient film technique and substrate beds) placed under identical conditions were evaluated. Quantitative analysis of ammonia, nitrite, nitrate concentrations and the factors on which they depend (air and fish water temperature, air humidity, pH and dissolved oxygen) was performed. The nutrient solutions affecting the yield and quality of the produce and the efficiency of the resources used were assessed. Monitoring and good management of aquaponics are necessary and mandatory requirements to ensure optimal conditions for the symbiosis between fish, beneficial bacteria and plants.
