摘要：Reproduction and organ structure of the pale chub,Zacco platypus in Isa stream were investigated by means of histological methods. The results of the study confirmed reproductive abnormality and histopathological features in the pale chub. The gonadosomatic index (GSI) of the fish showed two peak in April and August. In summer season,GSI of the male was about two times of the female’s GSI. Monthly variation of the gonadal development was very irregular. From the histological analysis of the organ structure,epidermal atrophy,necrosis and hyperplasia of pigment cell were observed in the skin. Epithelial layer lifting and clubbing of the lamella and bifurcation of the filament were observed in the gill. Also histological changes as congestion,cytoplasmic degeneration of hepatic cell,degeneration of bile duct,glomerular dilatation,degeneration of renal tubule and pycnosis of interstitial cell were identified in the liver and kidney,respectively.
