“…C. citratus (EOC) was only tested in L. vannamei . Concentrations between 0.150 and 0.500 mL·L −1 induced anesthesia within 2.5 and 1.8 min with a recovery time of between 4.2 and 6 min [ 101 ]. Lower doses between 0.005 and 0.010 mL·L −1 were also tested for long-duration anesthesia (6 h), when recovery took between 2 and 4 h, however concentrations above 0.015 mL·L −1 produced mortality in 1 h [ 58 ].…”

The concentration of L. alba (EOLA) recommended for anesthesia was 0.750 mL·L −1 for adults of the shrimps Penaeus pauliensis [ 101 ] and L. vannamei [ 57 ]. For the post-larvae of L. vannamei , the recommended concentration was lower than for adults to induce short anesthesia needing 0.6 mL·L −1 of EOLA [ 57 ].…”

“…However, a higher concentration (0.25 mL·L −1 ) of EOOG induced anesthesia but caused muscle spasms, escape responses, and 30% mortality. O. majorana (EOO) tested in L. vannamei , at concentrations of 0.40 and 0.80 mL·L −1 , induced anesthesia in 2.5 and 1.7 min and showed a recovery time of 5 and 10 min, respectively [ 101 ]. Lower doses (0.05 and 0.2 mL·L −1 ) were not effective in the first 30 min.…”

Methods to induce analgesia and anesthesia for research purposes, handling, transport, or stunning have been used in 71 species of crustaceans. A non-systematic literature search was conducted on crustacean anesthetic methods. This review presents a comprehensive evaluation of drugs and non-chemical methods used to provide analgesia and anesthesia in many crustacean species rather than just decapod crustaceans. This information allows users to select an appropriate method or agent for their species of interest. We prepared an on-line tool based on datasette, a no-code open-source solution for simple web-based database frontends that allows exploration and downloading data by method, analgesic/anesthetic, species, life stage, or sex, as well as other data including environmental conditions (temperature, salinity, light), route of administration, dosage, and induction and recovery times. These values can be selected to filter the dataset and export it to CSV or JSON formats. Currently, several techniques and chemicals are, in our opinion, unsuitable for use as anesthetics in crustaceans, and the basis for these opinions are presented. Given the evidence of a pain-like experience in crustaceans, we propose that researchers should treat crustaceans humanely, applying the principles of good handling, care, and the management of stress and pain to safeguard their welfare.

“…Their results indicate that the application of an anaesthetic significantly improves the elapsed time of feeding onset and their swimming behaviour. On the other hand, the effects of anaesthetics (clove oil/eugenol) have also been examined in a number of decapods, including P. vannamei (Parodi et al, 2012;Wycoff et al, 2018;Becker et al, 2021). Results from Wycoff et al (2018) show that P. vannamei was very susceptible to stress and therefore measurements of heart rate, motor nerve activity and sensory rate activity were inconclusive or not possible to perform.…”

Welfare in Farmed Decapod Crustaceans, With Particular Reference to Penaeus vannamei

et al. 2022

The farming of decapod crustaceans is a key economic driver in many countries, with production reaching around 9.4 million tonnes (USD 69.3 billion) in 2018. These efforts are currently dominated by the farming of Pacific whiteleg shrimp, Penaeus vannamei, which translates into approximately 167 billion farmed P. vannamei being harvested annually. Further production growth is expected in the future and hence the need for more research into its health and welfare is required. Herein, from an extensive survey of the available literature, we scrutinise farming practices and the challenges associated with the production of P. vannamei from an animal-centric welfare perspective (1), we propose potential welfare indicators (2) and we critically review current scientific evidence of sentience in penaeid shrimp among other commercially important decapods (3), since it is plausible that in the near future not only the largest, but in fact all decapod crustaceans will receive welfare protection. This review highlights that despite the wide knowledge on crustacean stress physiology and immunology as well as disease control, still little is known about some key parameters related to the five welfare dimensions. We recommend that further research should focus on developing a systematic integrated welfare assessment encompassing all the different aspects of the crustaceans farming and life cycle up to slaughter. Furthermore, direct and indirect species-specific operational welfare indicators should be developed for all decapod crustaceans currently farmed, similar to the ones suggested in this review for P. vannamei.

Anaesthetic effect of clove basil (Ocimum gratissimum L.) essential oil on the giant river prawn (Macrobrachium rosenbergii, De Man 1879) exposed to different water pHs

The increasing concern for invertebrate welfare has led to improvements in management procedures and protective legislation; under discussion is the use of anaesthetic agents to improve the welfare of farmed prawns. In parallel, the aquatic environments present changes in their physical and chemical characteristics, like the acidification of waters. With this perspective, our study analysed the effectiveness of Ocimum gratissimum essential oil (EO-OG) as a natural anaesthetic for Macrobrachium rosenbergii at different concentrations and water pHs. Juvenile M. rosenbergii were exposed to five different EO-OG concentrations (0, 100, 200, 300, and 400 μL L−1) and vehicle control (ethanol), at two water pHs (8.08 ± 0.10 and 6.42 ± 0.15). Induction time was EO-OG concentration-dependent regardless of water pH; i.e. the time required for sedation and anaesthesia decreased with the increase of EO-OG concentration. No correlation was found between recovery time and EO-OG concentration. The most effective EO-OG concentration was 400 μL L−1, with prawn sedation in 2.0–2.5 min, anaesthesia in 3.5–4.1 min, and full recovery in 16 min, regardless of water pH. The different tested water pHs influenced sedation time; i.e. sedation time was higher in mild acidic water than in mild alkaline water. Anaesthesia induction and recovery times were similar at both water pHs. Survival rates were 100% in all experimental groups. In summary, EO-OG is effective as a sedative and anaesthetic for juvenile M. rosenbergii in routine procedures, at the recommended concentration of 400 μL L−1, with mild alkaline water.
