Physico-chemical characteristics and zooplankton community of a dug-out pond in Ekpoma, Edo State, Nigeria
The physico-chemical characteristics and zooplankton community of a dug-out pond along Ukhun Road, Ekpoma, Edo State was studied for a period of six months (August, 1999 January, 2000). Composite water and zooplankton samples from different sections of the pond were taken for the study, at fortnightly intervals. The range of values observed for the parameters were temperature 28-31 degrees C (air) and 25-28 degrees C (water); Electrical conductivity (36.50-67.30 Scm-1) TSS 0.190.99mg/l; TDS (14.20-33.4mg/l); pH (6.15-6.70); DO (4.6-9.3mg/l); BOD (2.2-4.9mg/1); Chlorinity 35.50ppm); Total alkalinity (42.7-67.10mgCaC03); Phosphate-phosphorus (4.43-7.18mg/l) and Nitrate-Nitrogen (0.4-0.95mg/l). Heavy metals concentrations were generally low except for iron, which was moderately high. A total of 9 taxa and 696 individuals of zooplankton were collected. The major zooplankton groups identified were copepoda, cladocera and Rotifera The order of dominance exhibited by those major groups in this pond were cladocera > copepoda > Rotifera. The results revealed that such water body is suitable for fish culture.
