The effects of five different foods including: Blood worms, Artemia cysts, Artemia mass powder, Gammarus mass powder and ordinary commercial food were studied on Siamese fighting fish (Betta splendens) propagation efficiency during thirty days in a totally randomize design with 4 repeats. Experimental plots had been consisted of twenty 30˟30˟40 cm aquaria which a pair of male and female brood stocks was introduced to each one. Males and females were separated in each plot by a glass plate for 15 days in order to be prepared for spawning. The results of the experiment showed no significant (p>0.05) differences on spawned ova, ova diameter, and hatched ova among treatments. However, comparison of averages of referring factors showed that spawned ova, hatched ova, and ova diameter were better in those brood stocks that had been fed on Blood worm, whilst ,Ordinary commercial food treatment had resulted the weakest averages among dietary treatments.
