available materials with good strength and minimum cost. The roof was made of galvanized corrugated
roofing sheet. The cage was constructed using wood and wire mesh for the cage floor. The height of
the cage was 0.47m, length of 0.5m and width of 0.4m. The complete housing unit is as shown in
Fig.1.

4. Results and Discussion
Variation in pH level in the ponds
The pH value of the water in the various ponds through out the experiment varied between 5.9 and 7.0
in pond 1, 6.3 to 7.7 in pond2 and 6.6 to 7.8 in pond3. There were fluctuations in the values of the pH
in the ponds as shown in Fig 2. However the values of pH recorded in the ponds were within the
acceptable limit necessary for optimum growth of cat fish. The value of pH recorded at the control
pond was slightly higher than that obtained in pond 1. This must have been as a result of the
ingredients used in the preparation of the fish concentrates.
