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"
Development of least cost formulated feed for Tilapia rendalli in tank based grow- out culture system
Abstract:
An experiment was conducted at Bunda fish farm from
November 2009 to February 2010. Juveniles of Tillapia rendalli
of average weight 9.5 ± SD 0.5g were stocked in outdoor
concrete tanks and fed on diets of different plant protein sources
formulated at different crude protein (CP) levels. The results
indicated that fish treatments had significant effect on growth
and survival. Fish fed on Diet 1 had an average final weight
25.64±0.79g, Diet 2 had final average weight of 23.31±0.71g,
Diet 3 had final average weight of 21.71 ±0.80g and Diet 4 had
an average final weight of 23.00±1.12g and differed significantly
among treatments. Survival of the fish was highest in
Treatments 2 and 3 which were 85.5% and 85.6%, respectively.
Treatments 1 and 4 had low survival rates of 77.8 and 60%,
respectively. This study established a potential of using a
combination of local plant protein sources which was relatively
cheap, readily available and easily accessible to make least
cost feed for tilapia species in tank based grow out system.
Une expérience a été menée à la ferme de poissons à Bunda
de novembre 2009 à février 2010. Les Tillapia rendalli
juvéniles du poids moyen de 9,5 ± 0,5 g SD ont été stockés
dans des réservoirs en béton en plein air et nourris avec des
régimes alimentaires des différentes sources de protéines
végétales en protéines brutes formulées dans différents niveaux
(CP). Les résultats indiquent que les traitements de poisson
ont un effet significatif sur la croissance et la survie. Les
poissons nourris avec l’alimentation 1 a un poids moyen final
de 25,64 ± 0.79g, L’alimentation 2 a le poids moyen final de
23,31 ± 0.71g, L’alimentation 3 avait le poids moyen final de
21,71 ± 0.80g et l’alimentation 4 avait un poids moyen final de
23,00 ± 1,12 g et variés significativement entre les traitements.
La survie des poissons est la plus élevée dans les traitements 2
et 3 qui ont été respectivement de 85,5% et de 85,6%, Les
traitements 1 et 4 ont un faible taux de survie de 77,8 et 60%, respectivement. Cette étude a établi un potentiel d’utilisation
d’une combinaison de sources locales de protéines végétales
qui a été relativement peu coûteux, facilement disponible et
accessible à moins d’aliments pour les coûts et les espèces de
tilapia dans le réservoir à base de système de reproduction.
