Histological changes in the kidneys and gills of the stickleback, Gasterosteus aculeatus L, exposed to dissolved cadmium in hard water.
Damage to the kidneys and gills of the three spined stickleback Gasterosteus aculeatus have been investigated, using light microscopy after exposure of fish to 2 to 6 mg Cd2+ liter-1 hard water (299 mg liter-1 as CaCO3). Cytological breakdown of kidneys and gill tissue appears to be the cause of death, since oxygen uptake and cadmium excretion are impaired, leading to tissue hypoxia and fish poisoning.
