Anaesthetic effects of Datura stramonium Leaf on Heterobranchus bidorsalis Juveniles
Author(s): Adebayo SF and Olufayo MO
Abstract: Anaesthetic effects of Datura stramonium was investigated using aqueous and ethanol extracts on Heterobranchus bidorsalis juveniles as a natural anaesthetic. The treated fish reached anaesthesia within 25 min and recovered in the shortest time 12 min. There was a significant positive correlation between concentration and recovery time of aqueous extract (r=0.990; p<0.05) and ethanol extract (r=0.994; p<0.05) of Datura stramonium. The induction time decreased significantly with increase in concentration of aqueous extract (1.0-5.0 ppm) and ethanol extract (0.5-4.0 ppm) of Datura stramonium. Ethanol extract has the shortest induction time 12 min and recovery time 23 min 30 sec. The findings show that D. stramonium plant extracts are good anaesthethic agent; they are cheaper and have zero hazard effect on user thus D. stramonium could be used as anaesthetic in fisheries management.
