- Abstract: Water quality plays a vital and key role in estimating the diversity and abundance of phytoplankton in freshwater ecosystem. The water quality of freshwater body is rapidly deteriorating by various anthropogenic activities and diverse emancipations from the population growth, urbanization, and industrialization. The aim of present research work was to estimate the anthropogenic influence on water quality and phytoplankton diversity of upper Ganga basin. The water quality and plankton diversity of a Ganga River and its major tributaries was studied between September 2018 and September 2020 in eight sampling stations. Some physico‐chemical parameters like turbidity, dissolved oxygen, and biological oxygen demand showed a slight increase in sampling stations 7 and 8. Multi‐correlation was calculated between physico‐chemical parameters and phytoplankton density. Totally 31 genera of phytoplankton were recorded and represented by five groups, Bacillariophyceae (14 genera), Chlorophyceae (11 genera) Myxophyceae (4 genera), Euglenophyceae (1 genera), and Xanthophyceae (1 genera). Dissolved oxygen showed a direct influence on the distribution of plankton and also showed a positive correlation with phytoplankton diversity.

La calidad del agua de la masa de agua dulce se está deteriorando rápidamente debido a diversas actividades antropogénicas y diversas emancipaciones del crecimiento demográfico, la urbanización y la industrialización. El objetivo del presente trabajo de investigación fue estimar la influencia antropogénica sobre la calidad del agua y la diversidad del fitoplancton de la cuenca alta del Ganges. La calidad del agua y la diversidad de plancton de un río Ganges y sus principales afluentes se estudiaron entre septiembre de 2018 y septiembre de 2020 en ocho estaciones de muestreo. Algunos parámetros físico‐químicos como la turbidez, el oxígeno disuelto y la demanda biológica de oxígeno mostraron un ligero aumento en las estaciones de muestreo 7 y 8. Se calculó la correlación múltiple entre los parámetros físico‐químicos y la densidad del fitoplancton. Un total de treinta y un géneros de fitoplancton fueron registrados y representados por cinco grupos, Bacillariophyceae (14 géneros), Chlorophyceae (11 géneros) Myxophyceae (4 géneros), Euglenophyceae (1 género) y Xanthophyceae (1 género). El oxígeno disuelto mostró una influencia directa en la distribución del plancton y también mostró una correlación positiva con la diversidad del fitoplancton. Finalmente, se puede concluir que las actividades humanas, incluida la minería del lecho de los ríos, la construcción de presas y presas, han tenido un impacto negativo en la calidad del agua y la diversidad del fitoplancton. Aun así, este tipo de actividades deben revisarse con regularidad y pueden controlarse. … (more)
