Abstract
The anesthetic potential of geranium oil (Pelargonium graveolens L.) was evaluated in two freshwater aquarium fish species, the electric blue hap (Sciaenochromis fryeri, 2.00â¯Â±â¯0.61â¯g) and blue streak hap (Labidochromis caeruleus, 2.31â¯Â±â¯0.52â¯g). Fish were exposed to nine concentrations of anesthetic (25, 50, 75, 100, 125, 150, 200, 250, 300â¯Î¼lâ¯Lâ1). The induction time generally decreased significantly with increasing concentration of geranium oil for both of the fish species. The recovery time increased with the enhancing geranium oil concentration. Deep anesthesia took between 61.19â¯Â±â¯7.25â¯s and 165.43â¯Â±â¯6.78â¯s for S. fryeri and between 73.32â¯Â±â¯8.92â¯s and 171.12â¯Â±â¯10.74â¯s for L. caeruleus. Recovery occurred after 96â¯Â±â¯6.87â¯s (L. caeruleus), with the longest being 291.45â¯Â±â¯8.31â¯s (S. fryeri). The minimal effective concentration was 75â¯Î¼lâ¯Lâ1 for deep anesthesia for both two species, and 50â¯Î¼lâ¯Lâ1 was found as the minimal sedative concentration at the stage of loss of equilibrium. These findings suggested that geranium oil is a new potential anesthetic for two ornamental fish species.
