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 study
Animals- 25 Juvenile Convict cichlid fish with unknown sex and an average weight of 4.2 ± 0.5 g were used (n = 5 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 [0.3 and 0.5 g/l] of clove powder and [1.8 and 3 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 30 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
