1 Literature Review: Study of Seasonal variation in the physicochemistry of a small tropical reservoiraiba Reservoir, Iwo, Osun, Nigeria (Atobatele and Alex, 2008). Physico-chemical parameters showed obvious seasonality for ph, conductivity and turbidity, suggesting that these parameters play major roles in the limnology of the reservoir. Hardness and alkalinity values suggest that the reservoir water is good for aquaculture. Limnological of Keenjhar Lake, District, Thatta, Sindh, Pakistanwas studied by Lashari et al, (2009). The study deals with physico-chemical parameters such as, temperature, ph, alkalinity, chlorides, conductivity, total dissolve solids, turbidity, dissolve oxygen, calcium and magnesium. The study concluded that the variation in parameters were due to rain and flow of River Indus. Seasonal Variation of Physico-Chemical Characteristics of Water in Two Wetlands of TipturTaluk, Karnataka (Jagadeshappa et al, 2011). They studied that the physicochemical parameters play a vital role in the wetland ecosystems. The result of the investigations reveals that there is a fluctuation in the physico-chemical characters of the water this will be due to in flow and change in the temperature as season changes. Limnology of Fresh Water Reservoir Tighra, Gwalior M.P (Mahor, 2011). Physicochemical parameter like temperature, ph, biological oxygen demand, hardness, electrical conductance, total dissolve solid, phosphate, nitrate, dissolve oxygen were analyzed during the one year study period January to December He concludes that the water of the reservoir use for fish culture, irrigation, domestic and drinking purpose. Investigation of Physicochemical Status and Primary Productivity of Ana Sagar Lake, Ajmer (Rajasthan), India by Koli & Ranga, (2011) revealed Primary productivity and physicochemical values of the lake were found high, mainly due to sewage discharged, industrial effluents and the agricultural runoff by surrounding city population.

Among these 74 species to belong to Bacillariophyceae, 43 species to Chlorophyceae, 38 species to Cyanophyceae and 5 species to Euglenophyceae. The phytoplankton density was high (1705 cells l-1) during the summer season and low (760 cells l-1) during the winter season. Bacillariophyceae formed the dominant group. Physicochemical and periphyton/phytoplankton of Onah Lake, Asaba, Nigeria (Olele and Ekelemu, 2008). The data obtained revealed that the concentration of all the nutrients were higher during the dry season than the rainy season. Transparency was significantly lower in the upstream station as opposed to the downstream station that recorded a high value. Three division, eight families and ten species of periphyton were encountered. The most abundant periphyton species recorded are Closteriumspp (26.37%) Cosmariumspp (18.63%) and Ulothrixspp (16.56%). The least species encountered was Anabaena spp (2.88%). Comparison of physico-chemical parameters and phytoplankton speciesdiversity of two perennial ponds in Sattur area, Tamil Nadu (Rajagopal et al, 2010). Fifty species were identified belonging to Chlorophyceae, Bacillariophyceae, Cyanophyceae and Euglenophyceae. High value of physico-chemical parameters and low phytoplankton diversity were recorded in the Chinnapperkovil pond, whereas low value of physico-chemical parameters and high phytoplankton diversity were recorded in the Nallanchettipatti pond. Class Chlorophyceae qualitatively and quantitatively dominated in both the habitats when compared to other taxa. Phytoplankton species diversity and physico-chemical parameter profiles indicate the Chinnapperkovil pond to be meso-eutrophic whereas the Nallanchettipatti pond is oligoeutrophic. An Investigatedon the Seasonal Variation of the Phytoplankton Density on the Surface Water of Sapanca Lake, Turkey (Yilmaz and Aykulu, 2010).Total 54 phytoplankton species were recorded: Bacillariophyta 30, Chlorophyta 12, Cyanophyta 5, Euglenophyta 3, Dinophyta 2, Chrysophya 1 and Cryptophyta 1.

Diurnal change of water temperature and dissolved oxygen were also studied. Water Quality Oftighra Fresh Water Resevoir in Relation to Physico-Chemical Characteristics & Periodicity of Zooplanktons (Mahor, 2010). 38 species of Zooplankon are belonging to 29 genera of the following 5 group-rotifera, Copepoda, Cladocera, Ostracoda and Protozoa. Density of the different groups of zooplankton is more in the summer season than winter and rainy season. Polulation density of Zooplanktons recorded maximum density (328 units/l) and minimum density (96 units/l) in the month of September. Zooplankton Diversity and Physico-Chemical Conditions of two Wetlands of Jalpaiguri District, India (Datta, 2010). Rotifer group having more number of species 48 and Brachionus species (11) followed by Lecane (9). Only during premonsoon period rotifer and cladoceran diversity was significantly different in these two wetlands. Presence of higher number of copepods in all seasons signifies oligotrophic condition of these wetlands. Physico-chemical parameters indicate prevalence of good quality of water in both the wetlands but the wetland (Domohani Beel) having lesser zooplankton diversity experienced deterioration in water quality

7 during premonsoon season. During premonsoon period Domohani wetland experienced intense Boro cultivation having little water covered area with full of water hyacinth; and this poor condition reflects on its poor zooplankton diversity. Zooplankton diversity was significantly positively correlated with TSS, vegetative heterogeneity, and submerged macrophytes and negatively correlated with BOD and free CO2 of water. Study on the Diversity and Seasonal Variation of Zooplankton in a Brood Pond, Bangladesh (Roy et al., 2010). The recorded zooplanktons were under six orders mainly copepod (55%), rotifer (8%), cladocera (25%), ostracoda (9%), crustacean larvae (2%) and bryozoa (1%). Numbers of zooplankton groups were recorded to be the highest in December and copepod was the dominant order. Five physico-chemical parameters were analysed during study water temperature, salinity, transparency, dissolve oxygen and ph. They also observed the relationship of zooplankton with physico-chemical parameters on monthly basis. Water Quality Assessment of Vadgaon Tank Of Kolhapur (Maharashtra), with Special Reference to Zooplankton (Manjare et al., 2010).
