Occurrence and distribution of macrobenthic invertebrates in the lower Taylor Creek, Bayelsa State
The occurrence and distribution of macrobenthic invertebrates were investigated in relation to water flow and nature of bottom in the Lower Taylor Creek. Benthic samples were collected from 3 stations with Eckman grab, fixed in 4% formaldehyde solution with Rosebengal stain, sorted and preserved in 70% ethanol and identified in the laboratory under stereo or compound microscopes. Five (5) families of macrobenthic invertebrates (Tubificidae, Chironomidae, Naididae, Sphaeridae (Bivalvia) and Lumbricidae) comprising 7 species occurred in the samples. Tubificids formed 69% of the macrobenthic fauna and were distributed in all Stations. Station III with least flow and soft mud bottom had more significant number of organisms (p <0.05) than Stations I and II with silt and clay and silt and sand bottoms respectively. Water flow and nature of bottom, influenced the occurrence and distribution of macrobenthos in the Lower Taylor Creek.
