On Some Cases of Fish Anomalies in Fishes from the Port of Jubail, Saudi Arabia, Arabian Gulf

Abstract

Cases of deformities in the operculum, dorsal fin and cases of albinism, color disorder and hyperostosis were observed and examined in fish samples collected from the Jubail City, Saudi Arabia. An attempt was made in this study to find a possible relationship between these anomalies and several types of pollutants presents in the environment. The assessment of abnormalities was carried out by their diagnosis morphologically. All cases were not fatal as they occurred in adult individuals. The possible causes for such deformities as well as the suitability of this kind of study for environmental monitoring are discussed. Further studies are needed to relate specific pollutants with the observed types of deformities.
