Water samples taken from Boztepe Dam Lake monthly
between January - December 2014 period were observed in terms of zooplankton.
During the study, a total of 33 zooplankton species, 17 species from Rotifera,
13 species from Cladocera and 3 species from Copepoda were identified. Maximum number of zooplankton has been
recorded in May (271785 individuals/m3). The least the number of
individuals were recorded in February (5090 individuals/m3). The
maximum number of taxa were recorded in October with 17 species and the least
were recorded in february with 5 species. All of the zooplanktonic
species have been detected for the first time in Boztepe Recai Kutan Dam Lake.
Based on the total
number of individuals of zooplankton, Rotifera was dominant group in the dam
followed by Cladocera (39.4 %)
and Copepoda (9.1 %). Dominant Rotifera species was Keratella cochlearis
followed by K. quadrata. Bosmina longirostris was dominant Cladocera species. Cyclops vicinus
was the most observed Copepoda species. Rotifera has showed higher diversity
compared to other groups, reaching also high densities throughout the study
period. Keratella cochlearis K. quadrata, Bosmina
longirostris are indicators of eutrophic character
and were recorded frequently in high numbers, suggest that the lake may be eutrophic.
