Abstract EN
Fish kidneys are sensitive to chemical changes in the freshwater ecosystem because they are directly and constantly exposed to chemicals dissolved in the water.
This study evaluated nephrotoxicity in Wallago attu and Cirrhinus mrigala harvested from the Chenab River in an area of industrial and sewage waste disposal.
Induced histological alternation data were correlated to the severity of environmental degradation in order to determine whether this biological system can be used as a tool for environmental monitoring programs.
Kidneys from two fish species occupying different niches were collected and stored for 24 h in 10% formalin.
Control fish were collected upstream of the polluted river area.
Specimens were processed using topical histological methods.
The major histological alterations observed in both species were renal tubule myxospora, hyperemia, glomerulonephritis, degeneration of renal tubule cells, dilation of glomerular capillaries, presence of pycnotic nuclei in the hematopoietic tissue, epithelial hypertrophy, vacuolization, reduced lumen of renal tubules, and shrinkage of glomeruli.
Renal tubular atrophy, degeneration due to extensive degranulation, necrosis of glomeruli, glomerular expansion, absence of Bowman’s space, hypertrophied nucleus, necrosis and hyalinization of the interstitium, clogging of tubules, and regeneration of tubules was also observed.
Wallago attu exhibited the maximum incidence of moderate to severe changes and was defined as having the highest ‘‘histopathologic alteration index”.
These severe alterations were found to be related to environmental degradation, indicating the presence of stressors in freshwater.
Control groups showed normal tissue morphology in the kidneys.
