Water samples were collected weekly from just beneath the surface
of the pond between June and December 2011. The samples were concentrated
by use of sartorius filtration technique with a 0.45 μmmesh
size of acetate filter for identification of phytoplankton. Taxonomic keys
were used for identification [7,20–29]. Seven environmental variables
were measured in situ: temperature, dissolved oxygen concentration,
conductivity, total dissolved solid (TDS), salinity, pH, and oxidation reduction
potential (ORP) by using YSI 556 model oxygen-temperature
meter.
