    Anesthetic potential of geranium (Pelargonium graveolens) oil for two cichlid species, Sciaenochromis fryeri and Labidochromis caeruleus

    Can, Erkan; Kizak, Volkan; Seyhaneyildiz Can, Şafak; Özçiçek, Esin

    The anesthetic potential of geranium oil (Pelargonium graveolens L.) was evaluated in two freshwater aquarium fish species, the electric blue hap (Sciaenochromis fryeri, 2.00 ± 0.61 g) and blue streak hap (Labidochromis caeruleus, 2.31 ± 0.52 g). Fish were exposed to nine concentrations of anesthetic (25, 50, 75, 100, 125, 150, 200, 250, 300 μl L−1). 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 61.19 ± 7.25 s and 165.43 ± 6.78 s for S. fryeri and between 73.32 ± 8.92 s and 171.12 ± 10.74 s for L. caeruleus. Recovery occurred after 96 ± 6.87 s (L. caeruleus), with the longest being 291.45 ± 8.31 s (S. fryeri). The minimal effective concentration was 75 μl L−1 for deep anesthesia for both two species, and 50 μl L−1 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.

    Anesthetic efficacy of cymbopogon citratus essential oil as a herbal agent in two ornamental fish species

    Kizak, Volkan; Can, Erkan; Can, Şafak Seyhaneyildiz; Özçiçek, Esin

    The efficacy of Cymbopogon citratus essential oil (CcEO) as a herbal anesthetic agent was evaluated for two ornamental fish species, Sciaenochromis fryeri and Labidochromis caeruleus. Fish were exposed to various essential oil concentrations and the lowest effective concentrations were determined according to deep anesthesia (AD<3 min) and full recovery (RF<10 min) times. CcEO showed anesthetic traits and induced AD in S. fryeri and L. caeruleus. The lowest effective concentrations was 200 µl/L for S. fryeri (AD; RF → 122 ± 1.8 s; 638 ± 8.9 s) and 200 µl/L for L. caeruleus (AD; RF → 139 ± 6.9 s; 625 ± 11.1 s). At concentration of 25 µl/L C. citratus essential oil did not induce AD in both of ornamental fish species. No significant differences were found between fish species in terms of induction and recovery times for same concentrations excluding AD time of 200 µl/L concentration. Although the fastest AD were obtained by 300 µl/L, recovery times were prolonged and fish did not full recover in 20 min. Induction and recovery times for CcEO were significantly dependent on concentrations and negative relationships were recorded between AD and RF. Neither mortality nor adverse effects were observed on two fish species. As a result, CcEO showed anesthetic properties for S. fryeri and L. caeruleus.

    The efficacy of chamomile (Matricaria chamomilla) oil as a promising anaesthetic agent for two freshwater aquarium fish species

    Can, Erkan; Kizak, Volkan; Özçiçek, Esin; Seyhaneyildiz Can, Şafak

    The efficacy of anesthetic chamomile oil (from Matricaria chamomilla L.) was evaluated in two freshwater aquarium fish species, Electric Blue Hap (Sciaenochromis fryeri) and Yellow Princess (Labidochromis caeruleus). Fish were exposed to ten concentrations of anesthetic (0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0 ml/L). The optimal concentrations identified as 0.6 ml/L for deep anesthesia (A5) for both two species. The minimal sedative concentration at the stage of loss of equilibrium (A3) was found to be 0.3 ml/L. The induction time generally decreased significantly with increasing concentrations of chamomile oil for all treatment groups. Recovery time tended to increase with increased chamomile oil at concentrations lower than 0.7 ml/L, but after this concentration it decreased. Chamomile oil proved to be effective as an anesthetic for both ornamental fish species. These findings suggest that chamomile oil is a promising anesthetic agent for aquaculture. However, further studies should be focused on species based investigations on the effect of temperature, transfer of fish, and their effect on antioxidant and oxidant status, in order to gather further information.
