White-legged shrimp (Litopenaeus vannamei) is one of the most widely cultivated and economically important commodities in Indonesia. However, the quality of white-legged shrimp will decrease significantly right after death. With the development of the live shrimp market potential, technology in live transportation system has become increasingly needed. During live transport, the quality and survival of shrimp are closely related to the presence of stressors in transport environment. To reduce these stressors, a dry system of transportation can be carried out with cold anaesthetization pre-treatment which aims to reduce shrimps’ metabolic rate. In the process of cold anaesthetization, the rate of anaesthetization is an important factor that needs to be considered. This study aims to determine the most appropriate rate of cold anaesthetization in maintaining the quality of white-legged shrimp with the highest survival rate during dry transportation system. In this study, cold anaesthetization was carried out gradually at the rate of -6,5?/hour and directly with the initial temperature of 15? with each treatment including 25 samples of whitelegged shrimp which were then transported with straw as transportation media for 5 hours. During anaesthetization and revitalization, measurements of nitrite levels, ammonia levels, pH, and DO of water were carried out. Tests for survival, weight loss, proximate content, and energy content were also carried out before and after transportation. The results showed that the treatment group with gradual anaesthetization have the highest survival rate at 100% with the lowest weight loss. During anaesthetization and revitalization, nitrite levels do not increase. Meanwhile, the ammonia level increased along with the decrease in pH. White-legged shrimp with gradual anaesthetization had a higher oxygen consumption than the direct treatment group both during anaesthetization and revitalization. Proximate analysis showed that the main energy used in the gradual treatment group came from fat metabolism.
