Abstract
Physico-chemical parameters, sediment type and macrobenthic fauna of an estuarine creek and artificial pond in the
western re gion of Lagos lagoon were studied bet ween J anuary and July 2001. Temporal, physical and c hemical
parameters of the water and sedime nt wer e normal for the tropics, however the pH was alkaline throughout the
study and sedi ment was solely sil t. Succession had occ urred in the artificial pond, and de nsity and diversity of
macrobenthic fauna were low. Six species belonging to the phyla Annelida, Mollusca and Arthropoda occurred. The
effect of human induced stressors had resulted in an unstable physically controlled environment characterized by a
low density of a few species.
