Survey Of Macroinvertebrates And Zooplankton In Anya-Mgbe And Orii Miri Streams Of Umudike In Ikwuano LGA Umuahia Abia State
ABSTRACT
The
species composition and abundance of the invertebrate fauna community of
Anya-Mgbe and Orii miri streams, located between Lat 5°S and 29°N and Long. 7°W
and 39°E were analysed in two periods July (26-29lh) 2006 and November
(17-2011’) 2006. Marcoinvertebrates were secured with the use of a kick bucket
by kicking the littoral and bottom sediments while the zooplankton were secured
using a plankton net of 55p mesh. A large number of invertebrate fauna were
secured. The invertebrate community was composed of 95/229 individuals of
macroinvertebrates for both study periods and a total no of 66 & 71 were
recorded for zooplankton for both periods respectively. The overall fauna
composition and abundance were not significantly different at the study stations.
Rotifera were the most abundant zooplankton groups recorded for both periods;
for the macroinverbetrates, Hirudinea (leeches), were the most abundant during
the first sampling period while Odonata (dragonfly) were the most abundant
during the second period, resulting to increased faunal productivity in these
study streams.
