[...]low DO stressor can also lead to disease outbreak in fish population [24]. [...]this increase cannot be attributed to pollution load as no point source of pollution can be identified at these sites. [...]suitable pH limit of 6.5-9 has been reported by Boyd [13] for freshwater fish propagation. pH at all the polluted sites of the river was less than 8.0 and ranged from 7.41 ± 0.02 at VKPD to 7.91 ± 0.04 at ORB1. According to the present study, river Ravi is polluted with heavy metals especially Pb, and Mn whose contents higher than safe limits proposed for propagation of fish and aquatic life have been detected at a number of polluted sites. According to their study, order of metal content in river water was; Fe>Zn>Mn>Cr>Cu>Ni>Hg>Pb>Cd.
