This study aimed to investigate the effect of aloe vera gel coating (Aloe barbadensis Miller) with different concentration on quality and shelf life of fresh fish fillets Asian sea bass (Lates calcarifer) during refrigerated storage (4º) was performed. The desired concentration of 40%, 70%, 100% and a treatment of uncoated as controls. Chemical and microbial tests including TVB-N, TBA, PH , TVC and sensory analysis (color, odor, tissue and general) for treatments on days 1, 6, 11,16 was conducted. The treatments coated with the gel TVB-N and TBA from the sixth day showed a significant difference with the control treatment(p<0/05) And on the sixteenth day of treatment was seen in 40% best results. PH value also increased over time and was higher in the control of other treatments on the final day minimum value PH of the treatment was 70% sample. TVC value is significantly (p<0/05)  higher than the sixth day after the treatment was greater than the other and 40% on the final day had the lowest bacteria count. At the end of the control of chemical and biological indicators on the situation was unacceptable and sensory assessment higher than other treatments to control. As a result of this study, covering 40% and 70% Aloe Vera Gel addition to chemical factors and Asian sea bass fillet also had good effects on sensory index. And cover the gel with a concentration of 40% and 70% for the eleventh day is recommended.
