Survey of the effects of different levels of acidifier (Biotronic S. E. Forte) food additive on some growth performance, survival rate and body composition of barb (Barbus schwanenfeldi)

The aim of present study was to evaluate the effect of using different levels of acidifier (Biotronic S. E. Forte) food additive on some growth performance, survival rate and body composition of Barb (tinfoil barb) So food additive was used at levels of 0, 2, 4 and 6 g/kg in four experimental diets. A diet without acidifier was used as control. Diets were fed to three replicate groups of 16 fish with an initial weight of 2.7±0.03 g for a period of 60 days. 0 g per kg of acid supplement that weight capacity of 2.7 g average weight was 9.2 g. Also during this period, the highest increase in the height of the treatment 4 kg of acid capacity that the 2 / 1cm to 6 / 43cm, and the lowest rate of growth of the Group 0 kg of acid capacity is that of the 2 / 9cm the 7 / 2cm reached. At the end of the fishes of different treatments for scrutiny of the amount of protein, fat, ash and moisture to specialized laboratories analyzed corpus, which is the highest protein content of 15/47 for the treatment of 6 g per kg of acid
