probiotic effects of pediococcus acidilactici to enhance growth indices, gastric enzymes activity and chemical analyzed of whole body (%dry matter basis) in green terror fish (aequidens rivulatus)

in an eight-week time period, the implications of pediococcus acidilactici, as a probiotic, were examined on growth index and the activity of gastric enzymes of aequidens rivulatus (green terror) (0.388±0.0021) in a completely randomized system. the fishes were input into nine oval-shaped ponds of 120 liters capacity with the density of about 60 pieces per pond, and fed twice a day. this study include three treatments as 1) control treatment 2) the feed including fish oil and nutrient treatment 3) feed including fish oil complemented with p.acidilactici bacteria. in treatment number three, final weight (3.22 gr), sgr (3.65%/day), fcr (1.45), fer (0.87), per (0.38) had an improved condition compared with other treatments (p
