Seasonal variation in macroinvertebrate community of river Okpokwu


Author(s): Adadu MO, Garba AA and II Yusufu

Abstract: Seasonal variation in the macroinvertebrate community of River Okpokwu was determined for a period of two seasons. Different macroinvertebrate species were observed from River Okpokwu during this study. The macroinvertebrate species include Lanestis libycus, Bulinus globosus, Anaxipha exigua, Nepa cinerea, Penaeus monodon, Cambridge campus, Lumbricus terrestris. Of the macroinvertebrates, L. libycus was most abundant at Station B (78.40%) and Station C (68%) in dry and rainy season respectively while B. globosus was most abundant at Station A in both seasons. A. exigua was highest at Stations A (71.35%) and B (61.82%) in dry and rainy seasons respectively while N. cinerea was highest at Station B and Station C in dry and rainy seasons. P. monodon had the highest percentage abundance at Station A. There is correlation matrices (r) between macroinvertebrate species and physicochemical parameters in dry and rainy seasons for all stations from River Okpokwu. There was no significant difference in all the physicochemical parameters across the stations for dry and rainy seasons.
