The benthic macro invertebrate fauna and physico-chemical parameters in Okpoka creek sediments
was studied for a period of one year. A total of nineteen (19) species (Ophidonais serpentina, Arenicola marina,
Eunice harassi, Marphysa sanguinea, Capitella capitata, Notomastus latrella, Notomastus tenuis, Glycera
capitata, Glycera convoluta, Nereis diversicolor, Nereis pelagica, Nereis virens, Nephthys hombergi,
Nototropis swamidami, Cliberanus cooci, Iphinoe tripanosa, Chironomus ablabiesmia, Tellina nymphalis
and Tympanotonus fuscatus) of benthic invertebrates’ fauna belonging four (4) phyla (Annelida, Amphipoda,
Arthropoda and Mollusca), six (6) classes (Oligochaeta Polychaeta Crustacea Insecta Bivalvia and Gastropoda)
and twelve (12) families (Naididae Arenicolidae Eunicidae Capitellidae Glyceridae Nereidae Nephthyldae
Gammaridae Callianassidae Chironomidae Tellidae) were found in the Okpoka creek during the study.
Polychaeta with six (6) families and twelve (12) species and percentage composition of 63.2% occurred most;
followed by Crustacean with six (2) families and twelve (3) species and percentage composition of 15.8%. The
rest families (Oligochaeta, Insecta, Bivalvia, Gastropoda) each with a family and specie occurred least. pH had
a positive relationship with Ophidonais serpentine, Arenicola marina, Nereis diversicolor, Nereis pelagea,
Nereis Virens, Nephthys hombergi, Iphinoe tripanosa and Tellina nymphalis, whereas temperature was
strongly related with Arenicola marina, Notomastus latreila, Notomastus tenius, Marphysa sanguinea, Glycera
convoluta, Nereis diversicolor, Nereis pelagea, Nereis Virens, Nephthys hombergi, Iphinoe tripanosa,
Tellina nymphalis and Cliberanus cooci. A positive relationship exists between salinity and Notomastus latreila, Glycera convoluta Nototropis swamidami, Cliberanus cooci, Iphinoe tripanosa and Tellina nymphalis.
Similarly, dissolved Oxygen and Notomastus latreila, Notomastus tenius, Eunice harassi, Marphysa sanguinea, Marphysa sanguinea, Nereis diversicolor, Nephthys hombergi, Clibernarius cooci, Iphinoe tripanosa and Tellina nymphalis. Strongly related. Biochemical Oxygen demand exhibited positive relationship with
Ophidonais serpentine, Eunice harassi, Glycera capitata, Nereis diversicolor, Nereis pelagea, Nephthys
hombergi, Nototropis swamidami and Tellina nymphalis. Conductivity related strongly with Ophidonais
serpentine, Notomastus latreila, Marphysa sanguinea, Glycera convoluta, Nereis diversicolor, Nereis pelagea,
Clibernarius cooci, Iphinoe tripanosa and Tympanotonus fuscatus.
