Abstract
This study was conducted to investigate the dose-dependent acute-toxicity study of the fresh bark aqueous extract of Acacia pennata (L.) Willd. plant on three types of fish species, namely; Carassius auratus (gold fish), Danio rerio (zebra fish) and Cyprinus carpio (common carp) over a period of 24 hours in-aquaria. The mortality rate and stressful behaviour of fishes were monitored throughout the experimental period and recorded. The experimental fishes C. auratus, D. rerio and C. carpio started to show stressful behaviour towards the fresh bark aqueous extract of A. pennata at concentration 75 mg/L, 50 mg/L and 100 mg/L; whereas, the complete mortality was observed at concentration 225 mg/L, 400 mg/L and 500 mg/L over the period of 24 hours. The LD50 values of the fresh bark aqueous extract of A. pennata for the C. auratus, D. rerio and C. carpio were found to be 144.34 mg/L, 98.67 mg/L and 194.00 mg/L respectively. These results shows that the fresh bark aqueous extract of A. pennata plant is more toxic to the D. rerio fishes at low dose (LD50: 98.67 mg/L) as compared with other two types of fish species (C. auratus and C. carpio). The phytochemical screening study of the methanol bark extract of A. pennata was also done and its screening results shows that saponins, tannins, terpenoids, flavonoids and glycosides were present. This piscicidal dose-dependent study reveals that the fresh bark aqueous extract of A. pennata is more toxic to fishes at lower concentrations. Therefore, this plant bark can be extremely helpful to fish farmers for catching fish rather than using man-made hazardous chemicals.
