In this study, the effect of Nauplius Artemia (Nauplii Guard) and adult Artemia (Artemia Guard) in the preservative based on hydro alcoholic extract of Melissa Officinalis and Allium sativum, in order to introduce new Artemia products as aquatic food with domestic production capacity for use in ornamental fish breeding centers. Its effect on the rates of reproductive mortality, reproduction and survival rate of Poecilia reticulata were studied and evaluated. The obtained farm results show decreases the mean (±SE) significantly difference of mortality (percentage) of guppy breeding fish in feeding treatment with nauplii guard in female breeders compared to other experimental groups (p <0.05) and also increased the mean (±SE) survival rate of larvae in different treatments with significantly differences in the nutritional experimental group with live Artemia (p <0.05). Based on the results of this study, it can be suggested to use Artemia Guard and Nauplii Guard technology by replacing feeding with live and frozen Artemia in ornamental fish breeding centers. Firstly, biosafety in these centers is observed by preventing the entry of dangerous pathogens and these products are environmentally friendly. Secondly, the need to hatchery system for Artemia eliminated and thirdly, it is easy to access and easy to use.
