Planktonic Assemblage and Diversity in Dadin Kowa Dam Gombe State Nigeria

Abstract

Eight months Planktonic sampling of Dadin Kowa Dam Gombe State were carried out between July, 2011 and February, 2012. A total of twenty three (23) species of phytoplankton were identified under the major classes of chlorophyceae, cyanophyceae, baccilariophyceae and desmidiaceae. Chlorophyceae and cyanophyceae recorded the highest in term of species number representation. Out of the fourteen (14) zooplankton species identified, class protozoa recorded the highest in term of number of species; the other classes are rotifers, copepod and cladocerans. The Dam is said to be eutrophic as a result of the diversity of the planktons identified.
