The present study investigated low pH with calcium and without calcium treatment on gill histology
and ionoregulation of fish, Cyprinus carpio exposed to low pH 4.0 with low (normal water) calcium 6 mg/L
and low pH 4.0 with added calcium 15 mg/L treatment for a period of 96 h. The light microscopic studies
of the processed low pH with low calcium treatment, exposed gills showed marked histological alterations. The
lesions of the gills included hypertrophy of the filament and lamellar cells; hyperplasia of the filament and
lamellar cells, and deformities of gill arches, filaments and lamellae were seen. But in low pH with high
calcium treatment the gill lesins were minimum such as, hypertrophy, hyperplasia and proliferation of chloride
cells. In low pH with (normal water) low calcium treatment, plasma ionic levels (Na+, K+ Cl-) decreased as the
exposure period extended. In all the three experiments sodium level showing steep decrease ranging from
0.405, 21.382 to 8.411 at the end of 24 h to 32.965, 57.350 and 18.915 at the end of 96 h, respectively. Low
pH with high calcium treatment, the fish exhibited only a minor depression in the plasma ionic levels showing
minimum decrease of 4.952, 20.128 and 7.702 at the end of 96 h, respectively. Impact on gills and
ionoregulation were minimum in low pH with added calcium level due to the ameliorative effects of calcium.
The significant alteration in both the histology and electrolyte levels can serve as a biomarker of pollutant
exposure and effects.
