Abstract
The Studies on the physico-chemical parameters and plankton composition of Ajiwa
reservoir, Katsina State, Nigeria was carried out from May 2012 to April 2013; with the
aim to establish physical, chemical, and biological parameters (Plankton) of Ajiwa
reservoir. Three sampling stations were chosen; the physico-chemical and biological
parameter were determined using standard methods, procedures, and instruments.
The result revealed that; Water temperature (23.8 ± 0.8оC), pH (6.8 ± 0.1), Turbidity (99.3 ±
3.6NTU), Conductivity (129.9 ± 4.1μЅ/cm), Total Dissolved Solids (17.8 ± 0.3mg/L),
Nitrate-nitrogen (6.01 ± 0.3mg/L), Water hardness (88.8 ±1.4mg/LCaCO3), Dissolved
Oxygen (6.6 ± 0.3mg/L), Biochemical Oxygen Demand (3.2 ± 0.4mg/L), Phosphatephosphorus
(6.4 ± 0.2mg/L) and Water depth (5.4±0.3m) varied with months and seasons.
Analysis of variance indicated significant difference between seasons (P < 0.05); but no
significant difference in zooplankton and phytoplankton distribution and abundance
between the three stations (P>0.05). The result indicated phytoplankton percentage
composition as; Chlorophyta (57.66%), Bacillariophyta (25.70%), Cyanophyta (14.73%),
and Dinophyta (1.91%) while Zooplankton percentage composition were Rotifera (30.55%),
Copepoda (29.33%), Protozoa (22.27%), and Cladocera (17.85%); the morpho-edaphic
index indicate low fish potential yield in the reservoir. Water quality of the reservoir is
influenced by anthropogenic activities such as runoffs of inorganic fertilizers and pesticides;
the reservoir water is suitable for irrigational and domestic purposes in terms of most of the
physico-chemical and biological parameters analyzed. Hence, there is need for an effective
anthropogenic inputs control programme in the reservoir.
