increasing demand for fish meal and the predicted reduction in the fish-meal
supply in the world (Wijkstrom and New, 1989) it will be useful to determine
and utilize the protein-sparing capabilities of lipids in warm-water fishes.
Hence the aim of the present study was to investigate dietary protein, lipid and
feeding regime interaction and its influence on growth, protein utilization,
biological parameters and hematology of male Oreochromis niloticus.
MATERIALS AND METHODS
The study was conducted in Kegati aquaculture research station (Figure 1)
from September-December 2012. Kegati station is located at 0042’ 50.44S and
0344 47’ 59.4 E’ and at an altitude of 1974m in Kisii County.
Four different experimental diets were formulated containing the same
digestible energy. Two of the diets contained 35% crude protein while the
other two contained 25% crude protein. The crude protein was provided by
fish meal. The proximate composition of experimental diets is shown
in Table 1.
