“…Anesthetics have been widely used for aquaculture animals to avoid injuries and stress, ensuring the good quality and safety during the handling process and transportation [ 31 – 33 ]. Thus, it is important to assess the efficacy of the anesthetic dose in different aquaculture species [ 12 , 34 ]. In recent years, eugenol has been regarded as an effective anesthetic in many crustaceans [ 18 , 35 ].…”

Background Eugenol is the most commonly used plant anesthetic to relieve the stressors during various aquaculture procedures. This study aims to investigate the pharmacokinetics of eugenol in Pacific white shrimp by immersion baths in a simulated transportation. Results The pharmacokinetics of eugenol were firstly investigated in Pacific white shrimp by immersion baths of 300 mg L− 1 eugenol over 5 min (Treatment 1), 10 mg L− 1 eugenol during 24 h (Treatment 2) and a sequential immersion administration (Treatment 3). Concentrations of eugenol in hemolymph, hepatopancreas, and muscle were determined using Gas chromatography-tandem mass spectrometry (GC-MS/MS). After immersion bath of Treatment 1, the elimination half-life (t1/2z) values are 1.3 h and 11 h for hepatopancreas and muscles, indicating the rapid absorption and elimination of eugenol in shrimp. Under the Treatment 2 administration, the eugenol peak concentration is 6527.9 μg/kg in muscle, followed by 402.8 μg/kg in hepatopancreas, with the lowest concentration of 37.9 μg/L in hemolymph. Area under the curve (AUC0-∞) values lie in the order of muscle > hepatopancreas > hemolymph, suggesting that eugenol tends to accumulate in muscle by the immersion administration. Moreover, the average residence time (MRT0-∞) values of 38.6, 23.0 and 115.3 h for hemolymph, hepatopancreas and muscle are achieved, which may indicate that hepatopancreas is the main organ for elimination of eugenol. After combining the conditions in a sequential bath immersion of eugenol (Treatment 3), the maximum concentration (Cmax) values of eugenol are higher than those achieved in Treatment 2, indicating that accumulation of eugenol happened in haemolymph, hepatopancreas and muscle. In addition, the corresponding t1/2z values are 4.7, 14.9 and 47.6 h, respectively, suggesting the faster elimination from the tissues following sequential administration. After the immersion bath, eugenol concentrations in muscle of Pacific white shrimp are lower than 2.5 mg/kg at 2 h, 48 h and 24.5 h in Treatment 1 ~ 3. Conclusions A withdrawal period of 2 h, 48 h and 24.5 h following a 300 mg L− 1 of eugenol over a 5-min, 10 mg L− 1 eugenol concentration during a 24-h and combined conditions in a sequential immersion bath were suggested.

“…Eugenol is a widely used fish anesthetic. It has been reported to have a high efficacy in fish, crustaceans, and other aquatic species [1][2][3][4][5][6][7][8][9]. During handling and transport, eugenol can reduce the stress of fish, decrease the physical injury or mortality of live individuals, and facilitate the operations.…”

The edible safety of eugenol-treated fish is one of the concerns limiting the anesthetic applied in the aquaculture industry. The depletion of eugenol was investigated at different water temperatures under the simulated settings of sea bass handling and transport. Sea bass was exposed to eugenol at a concentration of 60 mg/L for 3 min, then immediately transferred to clean water to be purged for 24 h and sampled at different time intervals. The left fish were re-exposed to eugenol in a repeat of the first exposure, purged for 48 h in clean water, and sampled for eugenol detection. Under the simulated settings, the sea bass could accumulate more eugenol residue in fillet when exposed to water at a temperature of 20 °C than that at 13 °C. However, eugenol could be depleted much faster when the sea basses were exposed to the higher water temperature. The half-lives of eugenol in sea bass were 0.28 h and 0.29 h for the first and second purging stage at a water temperature of 20 °C, while at 13 °C, the half-lives were 2 and 4.5 h, respectively. Therefore, increasing the water temperature may be an effective way to accelerate eugenol depletion in fish fillet and reduce exposure risk for the consumer.
