Community composition of macroinvertebrates
A total of 24 species of living bottom invertebrates were identified
in the collected benthic samples from the area investigated
during the period of investigation. Of these, 10
arthropods, 5 annelids and 9 molluscs were recorded. Annelida
and Arthropoda occupied most population density (P.D.) of
total macrobenthic invertebrates (M.B.I.) in the area and represented
about 52% and 28% respectively. Mollusca represented
only 20% of the total P.D. of M.B.I. (Fig. 3).
Regarding biomass, Annelida and Mollusca ranked the first
and second positions represented by 68% and 27% of the total
biomass of M.B.I. in the area respectively, while Arthropoda
represented only 5% (Fig. 4).
