With the development of fish breeding industry in the country and increasing the number of breeders and buying fish, transmission and maintenance of fish known as one of the related chain to this industry. Preparation of fish, forming oxygen and transport of fish are parameters to be fitted in the survival and growth of fishes and will be affected to short-term holding and transferring. In this study 6 preparatory groups were chosen from extracts of Rosa damascene & Valeriana afficinalis with 3 repeats of control group. In this experiment the number of 420 green terrors (Aequidens rivulatus) exposed to determine patterns of physiological stress responses in the species. The most important response related to increase in 3 equal Cortisol levels (Max 146 ng/ml). After acute displacement, stress had a quickly increase in the levels of Cortisol. Result showed that, like other fishes, the distance and amount of stress have caused physiological response and reducing the amount of these stresses can lead the losses in transmission.
