“…After 24 h, T0, T2.5 and T5 fish returned to normoxic condition, but T10 group exhibited hypoxia signs, suggesting 10 mg/L thymol, although induced no detrimental effects on cell respiration after transportation, might alter the fish respiration and/or oxygenation after a while. The present results are in agreement with Santos et al (2020) who showed that application of anaesthetics during transportation mitigated plasma lactate elevation in fish.…”

The present study aimed at assessing the effects of addition of thymol [0 (T0), 2.5 mg/L (T2.5), 5 mg/L (T5) and 10 mg/L (T10)] to water on biochemical and antioxidant responses of common carp, Cyprinus carpio, during 3-h transportation. The lowest dissolved oxygen and ammonia levels after transportation were related to T2.5 and T5 treatments respectively. T5 treatment exhibited lower cortisol/glucose responses after transportation and 24 h after that, whereas T2.5 and T10 exhibited elevations in these parameters at the same times. Hyperammonaemia and hyperchloraemia were observed in T2.5 treatment immediately after transportation, but such changes were observed in all treatments, 24 h after transportation. Addition of 10 mg/L thymol to water prevented uraemia after transportation, but all thymoltreated fish exhibited uraemia, 24 h after transportation. Thymol treatment failed to mitigate lactate elevation immediately after transportation; nevertheless, T2.5 and T10 had, respectively, the lowest and highest lactate levels, 24 h after transportation.T5 treatment inhibited alteration in superoxide dismutase activity, immediately after transportation, and T10 exhibited a similar effect, 24 h after transportation. Addition of 2.5 mg/L thymol to water significantly increased catalase activity immediately after transportation, but such a response was observed in all treatments, 24 h after transportation. T2.5 and T10 exhibited higher malondialdehyde levels than T0 immediately after transportation, but such a response was observed in all thymol-treated fish, 24 h after transportation. In conclusion, addition of 5 mg/L thymol is beneficial in reducing water ammonia concentration and stress in carp during transportation.

“…In the present study, blood glucose levels increased with transport time, indicating that that under waterless conditions, the fish body needs to release more glucose to maintain normal metabolism as the amount of respirable oxygen decreases It was found that the muscle ATP content of turbot in MS-222- and eugenol-treated groups was significantly lower than that of turbot in the control group at the end of transport, while the blood glucose level was significantly lower than that of the control group. This result suggests that the anesthetics can reduce the energy metabolism of the fish during transport, which is also similar to the findings of Eduardo et al [ 29 ].…”

This study focused on the anesthetic waterless keep-alive transport technique for turbot. MS-222 and eugenol were used to anesthetize turbot and then the waterless keep-alive transport was conducted. The blood physiological changes and flesh quality changes of turbot were evaluated after cooling and during the simulated waterless transport. The results show that the temperature lowered from 13 to 2 °C, resulting in a decrease in moisture, fat and protein contents of all samples. Compared to the control turbot, the turbots treated with MS-222 and eugenol presented higher pH and glycogen content. During the simulated waterless transport, the pH, ATP and glycogen contents in MS-222- and eugenol-treated turbots decreased and the IMP and lactate levels increased. For the blood biochemical indices, blood glucose, cortisol and urea nitrogen increased with the increase in transport time in MS-222- and eugenol-treated turbots. At sampling time, the changes in blood physiological indices were significantly higher in the control samples than those in the MS-222- and eugenol-treated samples. The results indicate that the turbot samples treated with MS-222 or eugenol could reduce stress during cooling and simulated waterless transport.

“…Histopathological studies are critical to verify the sensitivity of the organs to toxic substances, mainly the gill epithelium, the dominant site of gas exchange and osmoregulation (Poleksic & Mitrovic‐Tutundzic, 1994). Few studies have been conducted on the histological effects on fish tissues of essential oils, which are used as anaesthetics (Bhuvaneswari et al, 2015; Santos et al, 2020; Veliseck et al, 2005). In this study, no pathological findings were found in the gills, skin and hepatopancreas of fish anaesthesized with lavender and cumin essential oil (400–500 mg L −1 ).…”

In this study, anaesthetic effects of cumin and lavender essential oils by comparing with clove oil were determined on common carp. Fish (mean weight of 10 g) were exposed to nine concentrations of essential oils (5–500 mg L−1). Anaesthesia induction, recovery times and mean lethal dose of essential oils (10 min LC50 concentration) were evaluated separately for each fish. In addition, histopathological effects of essential oils on the fish tissues including hepatopancreas, gill and skin were investigated. The results showed that when the dose of essential oils increased, the time to anaesthesia induction was shortened and the time to recovery from anaesthesia was prolonged. Cumin essential oil at 300 mg L−1 dose and lavender oil at 400 mg L−1 dose on common carp showed similar anaesthetic effects (sedative and deep anaesthesia) to clove oil (p > .05). At these concentrations, sedative (Stage 2) and deep anaesthesia (Stage 4) induction times were 105 and 187.5 s for cumin and 94 and 194 s for lavender respectively. Recovery times at these concentrations were 415 s for cumin and 477.5 s for lavender. Mean lethal dose of essential oils for carp were found as 450 mg L−1 for cumin oil and 500 mg L−1 for lavender oil. Histopathological examination revealed no lesion in gill, skin and hepatopancreas in essential oils group. In the light of these findings, it was determined that lavender and cumin oils can be used as effective and safe anaesthetic in common carp.
