TAILIEUCHUNG - Phytoplankton biomass and species composition of lake Gölbafli (Hatay Turkey)
The lowest diversity value was observed in the first station in January, 2001. Lake Gölbafli has mesotrophic characteristics due to the seasonal distribution of phytoplanktonic organisms. However, it will be necessary to conduct further physical and chemical analyses of the lake water to obtain more detailed information about the trophic status of the lake. | Turk J Biol 29 (2005) 49-56 © TÜB‹TAK Phytoplankton Biomass and Species Composition of Lake Gölbafl› (Hatay-Turkey) Mehmet NAZ, Mustafa TÜRKMEN Faculty of Fisheries, Mustafa Kemal University, Hatay - TURKEY Received: Abstract: Seasonal distributions of phytoplanktonic organisms in Lake Gölbafl› were investigated in samples collected from 2 stations between May, 2001, and April, 2002. At each station, monthly sampling was performed from the surface water. The flora consisted of 41 taxa belonging to Bacillariophyta (24), Chlorophyta (12), Pyrrophyta (2), Cyanophyta (2) and Chrysophyta (1). During the 1year study period, the most dominant group was Chrysophyta followed by Bacillariophyta, Chlorophyta, Cyanophyta and Pyrrophyta. The highest numbers of Chrysophyta were observed in both stations in May, 2001, January, 2002 and April, 2002. Bacillariophyta had the highest biomass in both stations, followed by Chrysophyta, Pyrrophyta, Chlorophyta and Cyanophyta. The monthly changes in diversity values were between and . The lowest diversity value was observed in the first station in January, 2001. Lake Gölbafl› has mesotrophic characteristics due to the seasonal distribution of phytoplanktonic organisms. However, it will be necessary to conduct further physical and chemical analyses of the lake water to obtain more detailed information about the trophic status of the lake Key Words: Phytoplankton, Seasonal distribution, Biomass, Diversity Gölbafl› Gölü’nün Fitoplankton Biyomas› ve Tür Kompozisyonu (Hatay-Türkiye) Özet: Gölbafl› gölündeki fitoplanktonik organizmalar›n mevsimsel da¤›l›m› iki istasyondan al›nan örneklerde, May›s 2001-Nisan 2002 tarihleri aras›nda araflt›r›lm›flt›r. ‹ki istasyonun her birinden ayl›k örneklemeler yüzey suyundan yap›lm›flt›r.
