Abstract:

Phosphorus and nitrogen release from sea bass food and faeces were investigated in estuarine Black Sea water. A rapid increase in phosphorus release was detected in both faeces and food samples for higher temperatures (15-20ºC) in first few days and thereafter it was decreased, but orthophosphate leaching from both faeces and food was slower at low temperature (8ºC). Ammonium release was slow in first few days of experiments but ammonium release increased in later periods and reached highest rate in day 11. Temperature affected the release of ammonium and phosphorus from both fish faeces and food.
