The present study was carried out to document possible histopathological changes in the kidneys of fish in the Red Sea (off the coast of Yemen). It noted that tissue change was thought to occur after reported water quality transformations due to industrial waste-water discharges and the accumulation of some heavy metal industrial effluents in the bottom sediments of the Red Sea coast water. The majority of fish examined showed some forms of kidney lesions, including separation of the tubular epithelium from their basement membrane, tubular vacuolization and hemorrhages. These degenerative changes indicated impairment of normal kidney functions. In addition, they demonstrated a direct relationship between the kidney pathology’s gravity and the level of accumulation of suspect metals in the bottom sediments.
