In this study, the effect of the color of the bedding of cultivating aquariums (white, black, green, blue) on growth performance, nutrition and biochemical composition of the body of large freshwater shrimp (Macrobrachium rosenbergii) post larvae was investigated. All laboratory and experimental stages of this study were carried out in the fall of 1397 and for 60 days in an ornamental fish plant located at the Faculty of Natural Resources, University of Guilan. At the end of the experiment, the growth and nutrition indices (weight gain, weight gain, specific growth rate, survival percentage, feed conversion ratio, dietary efficiency, protein efficiency ratio, status index, body length increase) and biochemical parameters of the body were measured. According to the results, the best growth and nutrition indices were observed in treatment 2, 3, 4 and 1, respectively. Body moisture content showed significant differences among treatments, and the highest and lowest levels were observed in treatment 1 and treatment 4 respectively. The percentage of protein and body fat in treatments 1 and 4 did not have any significant difference and the lowest values ​​were allocated. The percentage of protein and body fat in treatment 2 and then in treatment 3 were significantly higher. Also, the highest percentage of body ash was observed in treatment 2. Finally, it can be said that the color of the background of cultivated aquariums, especially dark colors such as black and blue, can have a positive effect on aquatic species.
