Abstract: The nutrients (nitrate, nitrite, phosphate and silicate) of thirty-two study stations in the Ilaje, coastal waters and Estuaries of Ondo State, Nigeria were studied in the month of August (during the wet season). These 32 stations consist of two Estuaries Awoye (A1 - A6), Abereke (AB1 - AB7), and anthropogenic impacted stations (I1 - I12) and control stations (C1 - C7). The aim of this study is to evaluate the eutrophication status of the Ilaje coastal waters and Estuaries in response to the stress caused by anthropogenic inputs from land use changes, agriculture, and industrial effluents.
