Abstract

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 unknown sex, with an average weight of4.2 ± 0.5 g (n = 5) for each experimental group per experiment).
Methods- 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 ofthe 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 fishes 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 agentcan be used in fish.
