Anabas testudineus was exposed for 24hrs to 96hrs with pesticide (chlorpyrifos 50% + cypermethrin 5% EC) at a concentration at 0.1, 0.15. 0.2 and 0.25 ppm under laboratory condition. The fish shows several histological changes in ovary and testis tissues. The histological changes observed in ovary like oocytes shrinkage, oocyte degeneration and fragmentation of ova were recorded in an increasing order of doses. Changes in testis included degeneration of germinal epithelium, interstitial cells and induce impairments of the structure of Semniferous tubules and spermatogenesis at increasing doses.
