Relationships Between Water Nutrients And Phytoplankton In Nanak Sagar Reservoir Of Tarai Region, Uttarakhand (india)
Study on abundance species of phytoplankton and their relation with water nutrients such as, nitrate, phosphate and silicates in the Nanak Sagar reservoir analyzed for various seasons such as Monsoon, Post-monsoon and Pre-monsoon from July 2014 to June 2015. The assessment of water quality of the reservoir reflects the uses of water, as well as the condition of the site from where water sample taken. It is also noteworthy that when intensive sampling has been carried out throughout a reservoir basin to generate a “true” mean for the more common tropic state variables such as nitrogen (0.33±0.01 mg/l), phosphorus (0.13±0.01 mg/l), silicate (3.28±1.16 mg/l) and phytoplankton (97233.25 ± 2503.78) concentrations. The volume-weighted mean values have often been statistically indistinguishable from those measured in the different zone. Based on our results, an inverse relationship between the concentration of phytoplankton with nitrate and phosphate was recorded at different zone during pre-monsoon and monsoon, but it was linear during winter season. A clear inverse relationship have been recorded between annual concentration of silica (r = -0.46, p<0.05) with diatom (Bacillariophyceae) production. Spatial and temporal distribution of nitrate phosphate and silicates may play a significant role in phytoplankton availability or possible interactions with plankton species.
