Correlative Assessment of Water Quality and Qualitative and Quantitative Fish Production from River Yamuna, In the State NCT Delhi

Abstract

River Yamuna originates from the Yamunotri Glacier at  a height 6,387 Metres. Earlier, the waters of the Yamuna  were distinguishable as "clear blue", as compared to the  silt-laden yellow of the Ganges. However, due to high  density population growth and rapid industrialization,  today Yamuna is one of the most polluted rivers in  India, especially around New Delhi, the capital of India,  which dumps about 58% of its treated or partially  treated waste into the river. Hence, water quality of  river Yamuna has widely been studied with regard to  physico-chemical characteristics. The paper presents  their impact of pollution on the production of fishes in  the state of NCT Delhi. The river Yamuna has been  reduced to a small stream due to sewage and industrial  effluents draining into it. Even though, the Govt. of  India is taking stringent measures to assuage these  pollution loads to save an ailing river to flourish the  aquatic life, revival is not so eminent. Due to that the  production and quality of fish is affected badly. Economical aspects of the state NCT Delhi has also  impacted.
