Abstract

An Ecopath model was applied to analyse the stability and development of the aquatic ecosystem in Ekperiama in the Niger Delta. A total of 23 functional groups were used to determine the key features of the aquatic system. Indicators of ecosystem stability and development analysed were: Ominivory index 0.17, connectance index 0.23, path length 2.6, relatively low biomass to throughput ratio 0.0013, acendency 56%, Finn’s cycling index 3.68, low primary production to biomass ratio 23.1 and ratio of total primary production to total respiration 0.46. These indicators are consistent with a system where moderate (or tolerable) exploitation generally drives back development to earlier stages suggesting a system in its developmental stage.
