THE ZOOPLANKTON OF RIVER ADOFI IN DELTA STATE OF NIGERIA

DOI: 10.5987/UJ-NJSE.16.006.2   |   Article Number: 917A9A6   |   Vol.12 (2) - September 2013

Keywords: zooplankton, composition, abundance, diversity, River Adofi

Some physico- chemical parameters were investigated alongside with the zooplankton of Adofi

River between June and November 2009. The nutrient levels detected were significantly very high.

Two taxonomic groups were identified; the rotifera and the Cladocera. The rotifers were the most

occurring species (15) constituting about 98.7% of the total zooplankton species while the Cladocera

recorded only two species with 1.3%. Of the phylum rotifera, the family Brachionidae recorded

six species constituting 40% of the total number of species while the other three families

Lecanidae, Proalidae and Trichocercidae had three species(20 %) each. Despite the equal species

composition of the three families, the family Proalidae(39%) was almost of equal abundant composition

with the family Brachionidae(39.4%} while the families Lecanidae and Trichocercidae

contributed 12.9%, and 7.1% respectively. The two species of Cladocera recorded were Ceriodaphnia

audragula contributing 1% abundance and Diaphanosoma leuchen having 0.5% abundance.

No significant difference was found between the physico – chemical parameters. However,

significant difference was found between the physico- chemical parameters and the zooplankton

abundance (P<0.01).
