Abstract/Description: | A probiotic bacterial strain, Bacillus subtilis, isolated from the intestine of Cirrhinus mrigala (Hamilton), was incorporated in ¢sh feed at four di¡erent concentrations (5 � 108 cells g�2, 5� 107 cells g�2, 5 � 106cells g�1 and 5 � 105 cells g�1) and fed to four species of livebearing ornamental ¢sh, Poecilia reticulata (Peters), Poecilia sphenops (Valenciennes), Xiphophorus helleri (Heckel) and Xiphophorus maculatus (Gunther) for one year duration to observe the effect of dietary probiotic supplementation on their reproductive performance. Sixty virgin females of each species were stocked separately in circular FRP tanks (350 L) and fed diets with varying levels of probiotic cells and control feed. Broodstock performance was evaluated based on gonadosomatic index (GSI), fecundity and fry production of female broodstock. The results showed that supplementation of feed with probiotics increased signi¢cantly (Po0.05) the GSI, fecundity and fry production of spawning females and length and weight of fry in all the four species of ¢sh. The number of dead and deformed fry were also signi¢cantly lower (Po0.05) in ¢sh fed with the probiotic feeds.The use of higher concentration of the probiont in diet did not always lead to signi¢ cantly improved reproductive performance of the spawners. Collectively, this study showed that female livebearers bene¢t from inclusion of probiotics in diet during their reproductive stages. |
