Histological aberrations of gonads caused due to nitrite toxicity in Gambusia affinis






Environment and Ecology 16(3): 645-647

Histological aberrations of gonads caused due to nitrite toxicity in Gambusia affinis

Mosquito fish were maintained in water containing 0 (control) or 1.25 ppm of nitrite for 4 weeks and then killed. The testes or ovaries were removed and examined histologically. Testes from treated fish showed a number of aberrations that were not seen in control testes, including ruptured seminiferous tubules, separation of sperm from the lining of the Sertoli cells, involution and rupture of the sperm cyst wall, and necrosis in spermatogonia, spermatocytes and spermatids.
