Effectiveness of a probiotic, Pediococcus acidilactici on the growth performance and hematological parameters in the ornamental fish, Green Terror (Andinocara rivulatus)

This research was conducted to define the effect of probiotic Pediococcus acidilactici (CNCMMA 18/5 M, Lallemand, France) on the growth performance and hematological parameters of the ornamental fish, Green terror (Andinocara rivulatus). In this regard, 120 fish Green terror with average weight and length of 3.93±0.20 (g) and 4.73±0.26 (Cm) were used and randomly release to the 12 aquarium. After 14 days period adaption aquariums. The hypotheses werestudied with use of four isocaloric-isonitrogenus ration containing 0, 109, 108, 107 CFU/kg probiotic, Pediococcus acidilactici, each with three replicates. Along the period, the fish were biometry every 21 days to compare their growth performance at each treatment, and after 84 days at the end of the period, blood samples were taken to evaluate the effect of test diets on heamatological parameters. The results showed that the growth performance had significant increase (P
