SUMMARY:

Known as the Malaysian giant shrimp, Macrobrachium Rosenbergii is one of the main species cultivated in aquaculture worldwide. With easy adaptation to the tropical climate and with characteristics suitable for breeding, Brazil has been encouraging its production, however, routine practices in the cultivation of this crustacean can generate stress, affecting its physiological state, harming its development, survival and also production. An important tool that can be used to minimize shrimp stress during the various stages of management are anesthetics - substances that reduce the animals' metabolism. Therefore, the objective of this study was to establish the appropriate concentration of Cinnamomum Zeylanicum essential oil to anesthetize this species, determining the induction and recovery time of the animals after exposure to this substance. The procedure included subjecting the shrimp to different concentrations of essential oil (700, 1,000, 2,000 and 2,500 µL L-1), observing the moment of induction and recovery from anesthesia, and then the animals were transferred to a tank containing only water where They were under observation for 24 hours to assess their survival. It was concluded that a concentration of 2,000 µL L-1 of Ceylon cinnamon (Cinnamomum zeylanicum) essential oil is suitable for use as an anesthetic for freshwater shrimp (Macrobrachium rosenbergii). However, more studies are needed to determine the concentration of this essential oil with the species studied.
