Abstract
The physico-chemical parameters of the drainage canal systems were monitored. The air temperature ranged from
23.0 to 32.0oC (mean: 28.4 ± 2.63oC). The surface water temperature ranged from 21.0 to 31.0oC (mean: 26.8 ±
1.97oC). The hydrogen ion concentration (pH) ranged from 5.35 to 7.20. The dissolved oxygen value ranged from
2.10 to 4.80 mg/l (mean: 3.85 ± 0.54 mg/l) while electrical conductivity value ranged from 0.15 to 1.90 Scm-1
(mean: 0.68 ± 0.37 Scm-1). Total dissolved solid ranged from 0.08 to 1.00 mg/l (mean: 0.34 ± 0.19 mg/l). The air
temperature positively correlated with conductivity and total dissolved solids (r = 0.29). Similarly, water
temperature positively correlated with conductivity and total dissolved solids (r = 0.24, 0.25, respectively). Also,
dissolved oxygen positively correlated with conductivity and total dissolved solids (r = 0.22, 0.21 respectively).
The abundance of Poecilia reticulata positively correlated with total dissolved solids and conductivity (0.23 and
0.24, respectively) while it negatively correlated with pH and dissolved oxygen (-0.12 and -0.16, respectively).
Though, these paired values were insignificantly correlated (P > 0.05), the values fell within the standard range for
sustainable fish production.
