Aquatic pollution results in physical, chemical deterioration of waterbodies causing destruction of fish and other biota. In addition, aquatic pollution may alsospread diseases in human beings and domestic animals through utilization of vegetablesand fodder grown within or near the polluted water areas. The prime purpose of thepresent study was to evaluate the effect of physic-chemical parameters on the growth ofOreochromis mossambicus in Malir River. The results oabtained during this studyshowed that the growth of O. mossambicus is affected by the variations in the physicochemicalparameters. Generally, the physical factors do not directly influence the fishgrowth but may cause some indirect effects. The present data of length and weightindicate that the growth of this fish is being greatly influenced by low dissolved oxygen& high salinity in water.
