Eugenol was tested for use as an anaesthetic on Nephrops norvegicus at three different concentrations (300, 600, 900 μL/L). Monitoring included the time taken to reach each sedation stage. Sedation stage was assessed by passive behaviours and reaction to direct stimulation. A concentration of 300 μL/L induced full anaesthesia in 56% of individuals taking on average (median time seconds ± SD) 849 ± 200 s. Concentrations 600 and 900 μL/L induced full anaesthesia in 439 ± 143 s and 277 ± 117 s respectively. Recovery times were not significantly different with an average time of 689 ± 39 s. Ovigerous (berried) and freshly captured females took longer to reach full anaesthesia and were quicker to recover compared to non-berried and captive females. Eugenol can be used as an effective anaesthetic for this species.
