dc.description.abstractThe Studies on fish fauna and phytoplankton population in relation to physico-chemical parameters of Gwaigwaye reservoir, Katsina State, Nigeria was carried out from May 2013 to April 2014; to establish physical, chemical, and biological parameters (Phytoplankton and Fish Population) of Gwaigwaye reservoir. Four sampling stations were chosen; the physico-chemical and biological parameters were determined using standard methods and procedures. The result revealed that; Water temperature (25.02 ± 0.170C) pH (7.54 ± 0.03), Alkalinity (3.69±0.09), Conductivity (129.43 ± 5.15μЅ/cm), Total Dissolved Solids (50.54 ± 0.57mg/L) Nitrate-nitrogen (0.21 ± 0.04mg/L), Water hardness (134.44 ± 3.06mg/LCaCO3), Dissolved Oxygen (3.98 ± 0.10mg/L), Biochemical Oxygen Demand (2.53 ± 0.08mg/L), Phosphate-phosphorus (0.19 ± 0.02mg/L),Chloride (5.09 ± 0.15mg/L),Sulphor-sulphate (0.21± 0.01) and Calcium (2.97±0.06mg/L) varied with months and seasons. Analysis of variance indicated significant difference between seasons (P < 0.05); but no significant difference in fish fauna, phytoplankton distribution and abundance among the four 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 Fish fauna percentage composition were Tilapia zilli (17.32%), Clariasgariepinus (16.17%),Oreochromisniloticus (15.27%),Latesniloticus (13.80%), Bagrus. bayad (12.91%), Momyrussenegalensis (9.90%), Labeosenegalensis (7.41%) and Synodontisclarias (7.28%). Water quality of the reservoir is influenced by anthropogenic activities,the reservoir water is suitable for irrigational and domestic purposes from the results of most of the physico-chemical and biological parameters obtained. Hence, there is need for an effective anthropogenic inputs control programme in the reservoir.en_US
