Reproductive biology and cryopreservation of milt of Alestes baremoze (Joannis, 1835) of Lake Albert, Uganda

This study is designed to generate knowledge relevant to the domestication, breeding, production and propagation of Alestes baremoze fish species in captivity through artificial spawning and in vitro fertilization. The study aims at broadening the scope of cultured fish in Uganda which currently is limited to two major species; the Nile tilapia (O. niloticus) and the African catfish (C. gariepinus). Successful cryopreservation of A. baremoze milt and recovery of the male genome for in vitro fertilization will be a starting point for conservation of this fish species. The next step following successful cryopreservation will be to recommend to policy makers the establishment of gene banks in anticipation for future restocking of the depleted fisheries resources. Further, this study will act as an initial step to future studies involving hybridization experiments and/or employing recent biotechnological advances in chromosome engineering and transgenesis.
Cette étude est conçue pour produire de la connaissance concernant la domestication, l’élevage, la production et la propagation des espèces de poissons Alestes baremoze en captivité par reproduction artificielle et par fertilisation in vitro. L’étude vise à élargir la portée du poisson élevé en Ouganda qui actuellement n’est limitée qu’à deux espèces principales : le tilapia du Nil (O. niloticus) et le poisson moustachu Africain (C. gariepinus). La cryopréservation réussie du sperme de l’espèce A. baremoze et le rétablissement du génome mâle pour la fertilisation in vitro seront un point de départ pour la conservation de cette espèce de poisson. La prochaine étape poursuivant la cryopréservation réussie sera de recommander aux décideurs politiques l’établissement des banques du gène afin d’anticiper le futur réapprovisionnement des ressources de pêche épuisées. De plus, cette étude apparaitra comme une étape initiale aux futures études concernant les expériences d’hybridation et/ou utilisant des avancées biotechnologiques récentes dans la technologie et la transgénèse de chromosomes.

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"
