Abstract
Water parameters and plankton diversity are very important for determining of fish production. The specific status of limnological characteristics and diversity of plankton in lake Budhram lake have been studied through seasonal surveys in two annual cycles 2015 - 16 and 2016 – 17. In the present study, water samples were collected from different locations of Lake Budhram, Mulugu district Telangana state, for physico- chemical analysis. The laboratory test of the collected water samples were performed for analysis of various parameters such as pH, Temperature, Total dissolved solids, Dissolved oxygen, Alkalinity, Total hardness, Chloride, phosphorus, BOD and COD the methods employed for the analysis as per standard methods recommended by APHA, WHO, ICMR. The obtained values are compared with the standard limits. The present study was intended to evaluate the seasonal variation on physico-chemical parameter and their relationship with plankton community of Budhram Lake. The nutrients dynamic of Budharam Lake exhibit considerable seasonal variation due to the rainfall and nutrient utilization of autotrophs. The phytoplankton groups are Chlorophyceae, Cyanophyceae, and Euglenophyceae. The highest plankton density was recorded during summer season while lower in monsoon season. The zooplankton groups are Rorifera, Cladocera, Copepoda, Ostracoda. Chlorophyceae appeared as the dominant group of phytoplankton in Lake Budharam during both the study years. During the first year of study period this group exhibited maximum density of (3221 org/L) followed by Bacillariophycea (2664 org/ L) Cyanophyceae (1435 org/ l) and Euglenophyceae (216 org/ l). Similarly chlorophyceae also registered maximum density of (3325 org/l) during second year period followed by Bacillariophyceae (2806org/L) Cyanophycea (1520 org/ l), and Euglenophyceae (227 org/ l). Annual densities of zooplanktons during the first year Rotifera appeared as dominant group of zooplanktons with higher density (1283 org/ l) during the second year of the study period followed by cladocera (579org/ l) copepoda (602 org/ l) and ostracoda (268org/l). During the first year of the study period Rotifera again contributed maximum density (1270 org/l) followed by copepod (539 org/ l) cladocera (485 org/L) and ostracoda (161org/L). The minimum number of zoo planktons and was recorded in the rainy. Phytoplankton and zooplanktons have a nominal positive relationship. Phytoplankton was increased or decreased with the relation with zooplanktons.
