The River Indus is one of the most extended water bodies in Pakistan. It is a source of drinking water, hydroelectric power generation, irrigation, agriculture and aquaculture. The present examination wanted to survey the river's physicochemical parameters and biodiversity from June 2016 to May 2017. Total eight stations have been selected along the Indus River, and 08 water quality parameters, i.e., temperature, salinity, dissolved oxygen, power of hydrogen, transparency, alkalinity, hardness, and total dissolved solids, have been checked from all stations on the spot and bring water samples in a plastic bottle. Fish samples were also collected from all stations, preserved all the samples in 10% formalin, and further investigated in the Fresh Water Biology Laboratory at the University of Sindh Jamshoro. A total of 45 fish species have been identified throughout the study period. [ABSTRACT FROM AUTHOR]

Indus Blind Dolphin is endangered species sighted in the Indus River from the Indus delta upstream to the Himalayan foothills prior to building barrages but the maximum number of this mammal is found in Guddu to Sukkur reach and lowest number at upstream of Guddu barrage and downstream of Sukkur barrage. Driving forces for water and dolphin reserve conservation are an agriculture-environmental trade-off, water use and alteration of rivers for irrigation and agriculture and inadequate consideration on the habitat of highly valuable species such as Platanista gangetica minor, water demand increase with urban development and industrial activities, water pollution from Industries and agriculture wastewater, fishery-dolphin conflict causes physical damage to dolphins by boat and unintended dolphins/fish catch by gillnet.This paper presents the assessment of threats to Indus dolphin population growth, water quality, and other risk activities in stretch Guddu to Sukkur barrages. The total 1419 Indus dolphin was counted during a survey of dolphin in 2019, while918 in2011 respectively between Guddu and Sukkur Barrages. As result, 501 Indus dolphin number has increased in a period of 8 years. The analyzed results reveal that all the tested parameters ie. pH; Cond, TDS; Cl, TH, Alk, SO4, and NO2 are within the permissible limits as per standards NEQS and WHO. Moreover, the Standard Deviation of all parameters shows low deviation at different locations. The correlation matrix of all parameters of collected samples. The pH has a very strong correlation with NO2, and SO4 has a strong relation with conductivity and total hardness, and alkalinity. [ABSTRACT FROM AUTHOR]

According to reports, the last comprehensive fish records from the Indus River were published in 1977. Although few recent studies have been conducted, they are limited to some confined localities, and hence there was a gap of comprehensive fish diversity analysis of the Indus River in Sindh province section. Therefore, the present investigation was performed to describe the fish fauna of the Indus River from its northern to its southern extremities. In order to establish fish diversity and distribution, the study was accomplished from June 2016 to May 2017 covering 8 sampling locations across the river. A total of 44 fish species, belonging to 35 genera, included in 18 families, and 9 orders were recorded. Family Cyprinidae was the most specious with 13 species followed by Bagridae and Cichlidae with 4 species each, and Siluridae with3 species. Alpha Diversity Indices study showed that the ichthyofauna diversity of the River was not high in comparison with previous studies. Shannon's index for the whole Indus River locations was 0.95 and the evenness index was 0.77. Sustained populations of exotic fish species were shown to have established in the Indus River.
