Artemia is not only a useful food with high nutritional value for most of aquatic larval stage but can also carry many additives. Under the controlled stress stimulates Artemia can manufacture heat shock proteins (HSP) that can induce the growth and survival of existing better. In present work the effect of feeding with nauplii without stress and having stress, Chicory root as a kind of prebiotic compared to formulated feed (control treatment) in a total of 7 tretments, on the growth indices and biometric parameters of post larval stage of Guppy (Poecilia reticulate) were investigated. 51 fishes in each treatment with the almost same size, was randomized in a 3-liter containers and fed for 35 days on 9% body weight. In the early and at the end of experiment the fishes were analyezed and compared biometricaly. The results of the studied parameters such as weight gain, elongation, specific growth rate, condition factor and percent of the weight gain showed that feeding feeding with stressed Artemia nauplius had better effect with exception on condition factor (P<0.05). The treatments fed with Chicory root and formulated food lost the competition with live foods treatments (P>0.05).
