Aquatic Macrophytes Diversity and Physico-Chemistry of Asu River, Southeastern Nigeria: Implication for Aquatic Ecosystem Management
Abstract
The species diversity of the aquatic macrophytes present in Asu River located in Akpoha community of Afikpo North Local Government Area of Ebonyi State, South-Eastern part of Nigeria and the physico-chemistry of the river’s water quality was studied. The physico-chemical parameters are major factors when considering the quality of water sample in relation to the presence of macrophytes in the aquatic ecosystem. The mean value of water temperature was 28.95°C. Total Dissolved Solids had a mean value of 35.25 mg/L. Conductivity, the mean value was 80.50µS/cm. The pH value was also recorded; the mean was 7.57. The dissolved oxygen had a mean value of 5.75mg/L. The family with highest species is the Poaceae which had a number of 15 species followed by the seedlings of aquatic weeds with 7 species and then the Cyperaceae with 6 species. The Onagraceae family with a total number of 2 species, and the rest of the families (Amarathaceae, Eraceaa, Azollaceae, Convolulaceae, Nymphaeaceae, Leguminosae, Pontederiaceae and Titiaceae) had 1species each. It was observed that the physico-chemical parameters of Asu River fall under normal range that shows a good water quality supporting the growth of the aquatic macrophytes.
