Abstract

Effect of probionts for Catla Catla fingerlings based on growth performance, feed utilization (FCR) and digestive enzymes Protease, amylase and lipase activities was investigated. The photosynthetic bacteria, bacillus subtillus (water probiotics) and lactobacillus subtillus (feed probiotics). Isolated from common carp ponds were added to carp basal diets as the probiotics in two forms: 1g. kg water probionts (Bacillus subtillus) and feed probionts (lactobacillus subtillus) and their mix.six aquaria with replicates for treatment and control were used. After 60 days feeding experiment with probiotic supplemented and non-supplemented control diets, The diets supplemented with probiotics showed significantly better results of growth performance and FCR than those with the basal diets (control diet). The mean digestive enzyme activities of all probiotics treatment groups were significantly different (P
