摘要：Aquatic ecosystems consist of physico-chemical and biotic components. Physico-chemical parameters are directly affecting to diversity of flora and fauna of water bodies. Madar Tank (24°41'3"N 73°36'20"E) was mainly built as a storage reservoir to fill water in Fatehsagar through a canal. Study was undertaken (seasonal study for two annual cycles) to assess different physico-chemical parameters, primary production and Zooplanktonic fauna of Madar. The mean value of physico- chemical parameters of water were analyzed such as pH (7.85), depth of visibility (81.38 cm), electrical conductance (0.745 mS/cm), TDS (476.61 ppm), chloride (115.83 ppm), alkalinity (124 ppm) and hardness (177.33ppm) that showed low mean values. Average dissolved oxygen level was recorded as 6.9 ppm while average nitrate and phosphate levels were 3.478 ppm and 2.6802 ppm respectively. The primary production was an analyzed 261.64mgc/m2/hr. On the basis of water quality parameters in general, Madar tank was found to be mesotrophic. During the present investigation, 10 species of Protozoans belonging to 9 genera, 31 species of Rotifers belonging to 14 genera were recorded. Along with these 17 species of Cladocerans belonging to 10 genera, 4 species of 4 genera belonging to Copepoda and 2 forms of Ostracods were also enlisted. After including occasional zooplankters like insects and their larvae, crustacean larvae, spiders and mites (2) total 68 forms of zooplankters were recorded.
