In the present study, the effect of aquatic acidification on the rates of energy consumption (Cr), absorption (Ar), conversion (Pr), and metabolism (Mr) were investigated on the juvenile fish Cyprinus carpio (10.18 ± 0.109 gr). The experimental fish C. carpio weretested in different acid waters (pH of 5.0, 5.8, 6.6, and control 7.2). The length of the experiment was 21 days for the evaluation of bio-energetics. The fish were nourished by the fresh beef liver. The experimental acidic (pH) media were maintained carefully throughout the research, after the experimentation the fish were subjected to the estimation of the bio-energetics. The IBP formula was followed to calculate the energy budget. The results have shown the declined Cr (69.75 J/g/day) and (F3, 68 p<0.05); Ar (96.28 (J/g/day); and (F3, 38, p<0.05); Pr (-30.76 J/g/day); and (F3, 54; p<0.05), the hyper-Mr (5.09 Energy metabolized KJ/animal) and (F3, 59 p<0.05) was obtained in the fish exposed to low pH 5.0, 5.8, and 6.6 respectively. The acidic waters adversely impair the Cr, Ar, Pr, and Mr of the fish were exposed to pH 5.0; 5.8; and 6.6. But the severe effects were found in the experimental fish, which were exposed to pH 5.0 and 5.8.
