Histopathological Changes of the Gill and Liver of Aphanius sophiae Exposed to Carbaryl

The present study investigated effects of the pesticide Carbaryl on the liver and gill of Aphanius sophiae over 9 days and concentrations of 0.5, 1 and 1.5 mg L‑1. The tissues were sampled on days 1, 5 and 9 after the start of the experiment for histological studies. The symptoms found in the gill were: hyperplasia, necrosis, peeling of secondary lamella, hyperterophy and epithelial lifting of secondary lamella, curling, fusion, clubbing and destruction of secondary lamella. The symtopms found in the liver were: vacuolation and necrosis of hapatocytes, necrosis of nuleous, regeneration of hepatocytes and autropy. The present study indicated that histopathological changes of the gill intensified over time while those of the liver decreased.
