Abstract Aim Aim of the study is to understand the changes in the growth of fishes due to manuring with cowdung and the synergistic effects with immobilized and free probiotic bacteria Lactobacillus sporogenes Methodology The fingerlings of commoncarp Cyprinuscarpio of1.21+0.21g size were used. The treatments include control(C), cowdung manure of .5gm per litre(T1), cowdung manuring with free cells of L. sporogenes 5x104cells/ml(T2) and cowdung manuring with immobilized bacteria at a concentration of bacteria 5x104cells/ml(T3). Each experiment had three replicates. The experiment was conducted for a period of 30 days. The growth and food utilization conversion efficiency were assayed. Final weight was statistically analyzed using MINITAB software and the results were presented. Results High food consumption and high growth was also found in C.carpio fingerlings treated with cowdung and immobilized bacteria(T3). Interpretation Immobilized cells can be effectively used in promoting growth and production characteristics of Cyprinus carpio which is also an ecofriendly biomonitoring tool.
