Modelling carbon and nutrient cycling in a simulated pond system at Ranchi

Impact of Jute Retting on Phytoplankton Diversity and Aquatic Health: Biomonitoring in a Tropical Oxbow Lake

“…They observed a considerable increase in Chlorophyceae during MON from PRM like the present study. The SWI was observed maximum (2.5) during October -December and minimum (0.5) occurred in August during MON [Mukherjee et al, 2010] like our study. In tune with this rhythm the minimum dominance was in October and the maximum in August.…”

Phytoplankton nutrient dynamics and flow cytometry based population study of a eutrophic wetland habitat in eastern India, a Ramsar site

“…31 There have been some sporadic reports regarding waste water management at the EKW. [31][32][33][34][35] The phytoplankton diversity of the EKW has already been reported by some of the present authors. [36][37][38] In the present investigation an attempt has been taken to explain the seasonal variations in phytoplankton population in response to changes in environmental variables of EKW with special emphasis on Flow Cytometry based cell sorting methods.…”

“…This was further supported by other studies from other EKW sites such as Dasgupta et al 62 During sewage treatment the microbial degradation of the sewage releases the nutrients stored in it, creating eutrophic conditions, which in turn support high rates of primary productivity. 32,35 The excretion of nitrogenous compounds by sh is also a source of NO À is the essential nutrient for many photosynthetic autotrophs and has been identied as the growth limiting nutrient. 59 However, in municipal and industrial waste-waters or effluents including biological treatment plants, NO 3 À concentrations are enhanced resulting in eutrophication.…”

Nighttime Dissolved Oxygen Dynamics and Growth Performance of Nile Tilapia Under Different Feed Loads

“…During the daylight hours, photosynthesis leads to an increase in the amount of oxygen, but after sunset the respiration and decomposition processes become dominant and draw on the oxygen content, so that its concentration decreases (Mukherjee et al, 2008).…”

“…Dense growths of algae contribute large amounts of DO in ponds during the daylight period, resulting in super-saturation of oxygen in the epilimnion, but consume substantial quantities of oxygen at night causing anoxic conditions in pre-dawn hours (Boyd, 1982;Chang and Ouyang, 1988). Mukherjee et al (2008) indicated that the change in the total inorganic carbon (total CO 2 ) due to photosynthesis, respiration and decomposition could be quantified by measuring the pH. Leiher et al (1988) indicated that the minimum oxygen concentration at dawn can be reached when the rate of carbon dioxide consumption by algae during daytime is exactly balanced by its rate of production due to respiration (cited in Mukherjee et al, 2008).The addition or removal of carbon dioxide changes the pH value through community respiration and photosynthesis, respectively.…”
