    Abstract: This study was conducted to evaluate the effect of dietary prebiotic immunogen on the reproductive performance of a livebearing ornamental species, platy (<I>Xiphophorus maculatus</I>). Fish were fed under four regimes, 0% (A), 0.5% (B), 1% (C) and 1.5% (D), immunogen mixed diet for a period of 26 weeks. Results indicated that Gonadosomatic Index (GSI), fry production, relative fecundity and fry length were significantly (p&lt;0.01) higher in group D as compared to the control (group A) and other experimental groups. The percentage of deformed fry was not significantly affected by the various dietary treatments (p&lt;0.05). Moreover, fry survival (%) was found lowest in control group. With the observed results, we are able to conclude that female platy fish broodstocks benefit from inclusion of prebiotic immunogen in diet during their reproductive stages.
