About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Aqua Culture and Fisheries"
Some aspects of reproductive biology of Oreochromis andersonii, Oreochromis machrochir and Oreochromis niloticus in ponds
Abstract:
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%).
L’étude sur la biologie de la reproduction des Oreochromis
macrochir, O. niloticus et O. andersonii a été réalisée pour
69 jours dans les hapas. Il n’y avait pas eu de différences
significatives (P> 0,05)dans le nombre et le poids des oeufs
incubés dans la bouche des trois espèces de poissons bien que
O. macrochir ait incubé le plus grand nombre d’oeufs avec le
poids le plus faible. Toutefois, il avait plus d’oeufs (P <0,05) par
rapport à d’autres espèces de poissons. L’indice de couvaison
pour O. niloticus (5,04 ± 1,87%) était le plus faible suivie par
celui d’O. macrochir (11,99 ± 3,59%) et d’O. andersonii
(14.72 ± 5,13%).
