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.
