Abstract

Stem-bark extracts of four different plants (Euphorbia royleana, Jatropha
gossypifolia, Nerium indicum and Thevetia peruviana) caused mortality and
biochemical changes in freshwater non-target fish Channa marulius. It was
found that dilute stem-bark powder was effective in killing the fishes. The ranking
of toxicity of four plants was N. indicum > E. royleana > J. gossypifolia and
T. perucviana. Biochemical changes were observed in gonad tissue, after exposure
to 40% and 80% of LC50 (24h) of stem-bark extract of all plants. Withdrawal
experiments, showed recovery in total protein, total free amino acid,
while partial slow recovery observed in glycogen level after 144 h on termination
of experiment. It has been suggested that the alterations at both level (metabolic
and enzyme) is due to activation of protein kinase C. These extracts show
mortality at higher concentration and recovery after 7th day of withdrawal. So,
the lower doses of purified form of stem-bark can be used as bio-pesticides for
the control of aquatic weeds without environmental hazards.
