to Copepoda have been identified from Keban Dam Lake Yurtbası Region. As
a result of Shannon Wiener species richness index analysis of Keban Dam Lake Yurtbası Region, species
richness was found highest in may (H′=2.72) and the lowest index value was found in february
(H′=0.91).
According
to Margalef index analysis of Keban Dam Lake Yurtbası Region, species richness
was found highest in may (D=3.86)
and
the least value was found in january (D=0.62). Among all zooplankton, Rotifera was represented
