Ansari Ekhalak, Gadhia Mohini and Surana Ranjana

Ichchhapore village pond situated in the Surat district of Gujarat state was selected to study the diversity of phytoplankton with reference to physico-chemical properties of pond water. Water samples were collected every month from December 2011 to November 2012 for phytoplankton (qualitative and quantitative) and water analysis for temperature, pH, total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), total hardness (TH), calcium hardness, magnesium hardness, total alkalinity, dissolved oxygen (DO), biological oxygen demand (BOD), chloride, phosphate, silicate, nitrate, nitrite and ammonium nitrogen. Total of forty six species of phytoplankton were identified belonging to Euglenophycae, Chlorophyceae, Bacillariophyceae and Cyanoophyceae. Maximum genera belonged to group of Chlorophyceae followed by Bacillariophyceae and Euglenophycae
