In experimental ponds total amonia solution, total nitrogen, phosphate and inorganic carbon varied between 0-1050), 178-1093, phosphate 0-88 and 130-5410 ug/lit ) respectively. During the growing season the total amount of nitrogen (N), phosphate (P) and carbon (C) were fluctuating between (0.7-1.9), (0.062-2.05), (49.71-130) mg/gr. The primary variation range was 0.98 and 8.9 carbon/m2 per day, COD was 11-109 and BOD was 0.4-16.35 mg/lit oxygen. The resultes showed that in spite of using inorganic manures 100-150 kg/ha Per day, the ponds still had the ability of digestion of inorganic carbon, nitrogen and phosphorus. In the majority of the ponds the rate of total sediment of inorganic C and P were increased during growing perioed. We can use also COD and BOD as the manuring rate indicator in fish pond ecosystems.
