Triclosan Influences on Reproductive Physiology of Climbing Perch in the Spawning Phase

Abstract The endocrine-disrupting effects of triclosan, an antimicrobial agent, and its involvement in reproductive responses mediated through different modes activity various fish species have been documented. present study aims to explore whether triclosan at environmentally relevant sublethal concentrations could influence the physiology Anabas testudineus spawning phase. Fish were exposed (0.009 9 µg L −1 ) (176.7 for 4, 7, 30 60 d during phase evaluating potential fish. Triclosan exposure caused a significant ( P <0.05) reduction level total protein gonads liver tissues while increasing blood plasma meet energy demand overcome metabolic stress. Impairment gonadal steroidogenesis was evidenced by activities 3β- 17β-hydroxysteroid dehydrogenases associated with alteration levels serum gonadotropins, sex steroid hormones vitellogenin. rate fecundity females declined sperm counts, motility viability males. Histological lesions further confirmed toxicity which turn contribute failure
