Physic-Chemistry And Littoral Macroinvertebrate Of Umoni River In Delta State Nigeria.

Water use for various human activities is a very high prevalent and demanding pursuit in the world. Many rustic Nigerians fetch and consume waters without proper scrutiny. The study was directed at estimating the physic-chemistry of water and macro benthic invertebrate diversity of Umoni River. Macro benthic invertebrates were obtained using kick sampling techniques while water samples were detailed using standard methods of analysis. Results disclose that Annelida Ephemeroptera and Coleoptera were preeminent consisting 27.00 and 16.13 respectively of total abundance. Waters from Umu River were ethically oxygenated 4.3 - 6.1 mgl contained low BOD5 1.6 3.1 mgl and had a controlled flow rate 0.22 0.36 ms. All in all 18 taxa in total were encountered from the 6 months sampling February July 2017 with all macro benthos represented in all stations except Naucoris spp Hemiptera species and Hydrophilis spp. Coleoptera species not occurring in all sampled stations. The high incidence of Annelida Ephemeroptera Coleoptera Diptera in abundance and no plecoptera and low abundance of Tricoptera 3.83 indicates the waters of Umoni to be of moderately polluted.
