The enhancement of growth parameters in common carp (Cyprinus carpio) larvae using probiotic in rearing tanks and feeding by various Artemia naupli
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2011, Vol 4, Issue 4
Abstract
In probiotic trials the blend of Bacillus circulans and Bacillus licheniformis were added in rearing tanks of common carp at a concentration of 1×10[sup]3[/sup]CFU mL[sup]-1[/sup]. Artemia urmiana (Gunther, 1899),Artemia franciscana and Artemia parthenogenetica nauplii were administered as live food to common carp larvae. Within treatments, final body weight (FBW), specific growth rate (SGR), thermal growth coefficient (TGC), daily growth coefficient (DGC), relative gain rate (RGR) were affected by probiotic bacillus (P<0.05). These growth and feeding parameters of protein efficiency ratio (PER), lipid efficiency ratio (LER) and energy efficiency ratio (EER) significantly increased in treatment of G.P-bacteria and G.Fbacteria where the common carp larvae fed on with A. franciscana and A. parthenogenetica. The highest growth and feeding parameters were obtained in treatment of G.P-bacteria while in treatment of G.Ubacteria were significantly (P<0.05) lower than other treatments. The best feeding performance of common carp larvae was obtained by feeding of A. parthenogenetica nauplii in trial of probiotic (G.Pbacteria).
