Evaluation of the Anesthetic and Tranquilizing Effects of Clove Powder (Syzygium aromaticum) and Lavender Oil (Lavandula officinalis) in Convict Cichlid Fish (Cichlasoma nigrofasciata)

Objective- The present study describes the anesthetic effects of essential oil of Lavender (Lavandula officinalis) in Convict cichlid fish (Cichlasoma nigrofasciata) in comparison with clove powder (Syzygium aromaticum).Study Design- experimental studyAnimals- ۲۵ Juvenile Convict cichlid fish with unknown sex and an average weight of ۴.۲ ± ۰.۵ g were used (n = ۵ for each experimental group per experiment).Methods- The fish were divided into five groups, initially with five fish per group. Each group was subjected to one of four final concentrations [۰.۳ and ۰.۵ g/l] of clove powder and [۱.۸ and ۳ cc/l] essential oil of Lavender and control group was for determination of the basal values for blood parameters. The times for sedation, pre-anesthesia, and anesthesia were recorded based on the behavioral events seen after exposing the fish to each aquarium. After induction of anesthesia, the fish were transferred to anesthetic-free aquariums, and recovery time was recorded. Blood samples were taken by dissecting peduncle just ۳۰ minutes after fish were placed in water contain anesthetics.Results- essential oil of Lavender had efficacy to anesthetize the fish, and its sedation was similar to the clove powder at a commensurate concentration in Convict cichlid fish. However, the anesthesia form was different.Conclusions and Clinical Relevance- Lavender oil as a sedative and anesthetic agent can be used in fish
