Abstract

The aim of this study was to assess the effect of four levels of local probiotics compared to commercial probiotic as a biological control on common carp Cyprinus carpio growth parameters, specific growth rate (SGR), food conversion ratio (FCR) and survival rate. Fish (average weight 57.85 ±0.3g) were fed 0.05, 0.1, 0.25 and 0.75 mg kg d.w-1 local probiotic compared with 2 mg kg d.w-1 fed of commercial probiotic and control group without additive for 42 days. Highest level of probiotics (0.75 mg kg d.w-1) showed significantly increases on the SGR and FCR (P ≤ 0.05) compared to the other groups. Also, survival rate recorded 94.6% in comparison to control group (72.1%), suggesting that the high level of probiotics induces significant increases on growth performance which have profound may implications for the global aquaculture industry
