Eruvbi Stream

This study was conducted in Eruvbi stream, Benin City Edo State, Nigeria, aimed at investigating community structure of cladocerans in Eruvbi stream. The sampling period was carried out from the early dry season in march 2023 to the early rainy season period of My 2023.Three sampling stations were selected. Water samples were collected in 3 replicates monthly. Fifteen (15) Physico-chemical parameters including, pH, Electrical Conductivity, Total Suspended Solids, Dissolved oxygen, Biochemical Oxygen Demand, Nitrate (NO3), Suphate (SO4), Phosphate (PO4), Calcium (Ca), and Magnesium (Mn) were analyzed using standard methods. Phosphate and Nitrate were the only two Physico-chemical parameters with significant difference(p<0.05) among all the physicochemical Parameters of the stations. Seven Species were uncovered within the Eruvbi stream wiz; Alonella excise, Bosmina longirostris, Moina
micrura, Pleuroxus hamatus hamatus, Acroperus harpae and moina macrocopa, Amongst which station two results appeared to have the highest diversity and evenness, while Station 1 has the lowest diversity but relatively even distribution of species. Station 3 falls in between in terms of diversity and evenness. Thus, the findings of the research study provides crucial in understanding the health and ecological dynamics of the Ervubi stream and may have
implications for conservation and management efforts.
