Abstract

Gill structure of Barbus sharpeyi (Gunther) juveniles has been
studied, they were exposed to various concentrations of copper. Gill
damage resulting from exposure to sub lethal concentrations.
Histological changes in the gills included hyperplasia of the gill tissue,
some engorgement with bleeding in the secondary lamellae, epithelial
separation, necrosis, and fusion of adjacent secondary lamellae. The
result of experiment shows that the behavior of susceptible fishes to
high concentration(3ppm) after 3 hr. of exposure to the ion, starting
with swimming close to water surface circulation movement and
hemorrhage in gill lamella.
