In the research, fish measuring 4-6 cm and weighing 4-5g were used. The test fish were fasted for 3 days to reduce metabolic activity before being transported. Before packing, a treatment solution is made according to the concentration, namely 4 mg/L, 6 mg/L, and 8 mg/L. Test fish that are placed in the treatment solution are observed for the time required during the fermentation process. Fish that have been knocked out are placed in a transportation container in the form of low-temperature sawdust and lined with gauze and ice. The test fish were then transported for 12 hours and the fish were placed back in a container containing clean aura. The number of fish that died for each treatment was recorded.
