Plant based protein sources are one of the best, cost effective and easily available protein sources being used in fish feed. But due to a lower number of micro-biota in fish gut plant meal based diets cannot be digested and absorbed well in fish body. Probiotics were supplemented at 0, 1, 2, 3, 4 and 5 gkg -1 levels in fish feed for formulating one control and five test diets. In this study, three replicates of each treatment HIGHLIGHTS  Maximum improvement in growth parameters was observed in Cyprinus carpio fingerlings fed corn gluten meal based diet supplemented with 2 gkg-1 level of probiotics supplementation. C. carpio fingerlings fed with 2 gkg-1 level based diet showed higher values of RBCs, WBCs and platelets whereas 3 gkg-1 level showed second higher concentrations of blood parameters. Highest carcass composition was noted when fingerlings were fed with 2 gkg-1 level while the second higher level of these parameters were noted at 3 gkg-1 level based diet.Hussain, S.M.; et al.
