Abstract:

The phytoplankton of the Hirfanlı dam lake was investigated monthly between August 2008 and July 2009. The samples were taken using plankton net with a pore diameter of 55 μm. A total of 69 taxa belonging to 6 divisions have been identified, including Bacillariophyta (32 taxa), Chlorophyta (18 taxa), Cyanobacteria (11 taxa), Euglenophyta (2 taxa), Charophyta (4 taxa), Miozoa (2 taxa). Seasonal distribution of phytoplankton was also investigated. Seasonal increase rate was determined higher in spring, summer, and autumn. Even though seasonal distribution of phytoplankton species varied, Navicula sp., Cyclotella sp., Nitzschia sp., Gomphonema sp., and Lyngbya sp. were found as dominant.
