✦ Synopsis

The nucleic acids (DNA and JXNA), protein content,s and the activity of alkaline phosphatase was significantly decreased in t.he ovary of Bruchydanio rerio after exposure to different concentrations of malathion, an organophosphorus pesticide. T0t.d free amino acids and acid phosphittnse act,ivity, however. were enhanced. The decrease in the measured parameters depended on both concentration and time. Histopathological studies revealed developmental arrest at a11 levels from oogonium t,o tertiary stage oocytes. After transfer to fresh water without the pesticide, there was a marked trend of recovery in all the parameters st,iidied.
