Physicochemical Parameters of River Water and their Relation to Zooplankton: A Review

Abstract Rivers are dynamic systems that respond to various physicochemical characteristics. In this review, we focused on the most important parameters influenced zooplankton composition and diversity in rivers, including water temperature, dissolved oxygen, biochemical oxygen demand, hydrogen ion concentration, electrical conductivity, salinity, total solids, suspended turbidity, hardness, calcium, magnesium, alkalinity, bicarbonate, phosphate, nitrate, sulphate, velocity. As well as, define these environmental factors determined minimum maximum values for each factor. general, can be concluded exceed standard affected negatively diversity.
