The study on the reproductive biology of Oreochromis
macrochir, O. niloticus and O. andersonii was carried out
for sixty nine days in hapas. There were no significant (P >
0.05) differences in the number and weight of spawn incubated
in the mouths of the three fish species although O. macrochir
incubated the largest number of eggs with the lowest weight.
However, it had longer (P < 0.05) eggs compared to other fish
species. The brooding index for O. niloticus (5.04 ± 1.87%)
was the lowest followed by O. macrochir (11.99 ± 3.59%)
and O. andersonii (14.72 ± 5.13%).
