Essential oils from inflorescences (AOOi) and leaves (AOOl) of Acmella oleracea .

Silver catfish exposed to 20 mg L- 1 of AOOi took longer to reach stages S2, S3a and S3b than those subjected to 80 and 100 mg L- 1. Furthermore, 80 mg L- 1 took less time to reach S4 than those subjected to 20 and 100 mg L- 1. Only fish anesthetized with 20 and 80 mg L- 1 recovered within the 30 min evaluation time ( Tab. 4 ). Considering the AOOl concentrations evaluated, the time to reach the S2 stage was inversely proportional to the increase in concentration. The concentration of 100 mg L- 1 took longer to reach the anesthetic stage (S4) than 50, 200 and 300 mg L- 1. However, the concentration of 100 mg L- 1 was the one that recovered in the shortest time compared to the concentrations of 200 and 300 mg L- 1. However, it did not differ from 50 mg L- 1 in terms of anesthetic recovery time ( Tab. 4 ).
