Physico-Chemical Variables and Fish Parasites of River Neelum Azad Jammu and Kashmir, Pakistan

Abstract

The physico-chemical parameters and the fish parasites of the River Neelum were studied at three sampling sites, i.e., Pattika, Tali Mandi, and Domail. Water temperature and rate of flow of water were significantly higher at Domail than Pattika and Tali Mandi. ANOVA showed that dissolved oxygen, total suspended solids, inorganic suspended solids, and organic matter of the bottom mud kept on fluctuating and showed a significant difference between three selected sites. Although, these variables showed variations, they remained within tolerable limits set by WHO. Three species of potentially harmful parasites, i.e., Dactylogyrus vastator, Procamallanus laevionchus, and Argulus foliaceus were isolated from fish population of the River Neelum, however, these parasites do not pose any severe threats to general fish life
