Piscicidal activity of alcoholic extract of nerium indicum leaf and their biochemical stress response on fish metabolism
Journal Title: African Journal of Traditional, Complementary and Alternative Medicines - Year 2004, Vol 1, Issue 1
Abstract
Laboratory evaluations were made to asses the piscicidal activity of ethyl alcohol extract of Nerium indicum leaf against predatory fish Channa punctatus and their ultimate mode of action on fish metabolism. Toxicity experiments show there was significant negative correlation between LC values and exposure periods i.e. LC50 value decreased from 66.32 mg/L (24h) to 44.96 mg/L (96h). Biochemical studies show that after exposure to sub lethal doses of alcoholic extract, pyruvate level and activities of acetylcholinesterase and cytochrome oxidase significantly decreased while lactate level and activities of alanine aminotransferase and aspartate amino transferase were significantly enhanced in both liver and muscle tissues of Channa punctatus. The alterations in all the above biochemical parameters were significantly (P
