Hatchery system evaluation and adaptation for the production of Oreochromis karongae (Trewavas, 1941) fingerlings

Abstract: 
In Malawi development of aquaculture is constrained by, among other factors, lack of good quality seed. Through Research into Use (RiU) the Government of Malawi has mandated a few fish hatcheries, of which the most prominent is the Commercial Tilapia Hatchery at The National Aquaculture Center (NAC), Domasi, Zomba to produce seed. However, this state of the art hatchery, based on technology from Thailand, faces challenges in the production of consumer preferred Oreochromis karongae fingerlings. This study seeks to evaluate the hydraulic, economic and biological characteristics of the system and adapt it for the successful production of O.karongae fingerlings.
Au Malawi le développement de l’aquaculture est constraint, parmi tant d’autres facteurs, par le manque de graine de bonne qualité. Par le canal de RiU (Research into Use: recherche dans l’utilisation), le gouvernement du Malawi a exigé quelques établissements d’incubation de poissons, dont le plus proéminent est l’établissement d’incubation commercial de Tilapia au centre national d’aquiculture (NAC) à Domasi- Zomba pour produire la graine. Cependant, cet établissement d’incubation de haute performance, basé sur la technologie thaïlandaise, relève des défis dans la production des poissons jeunes Oreochromis karongae préférés par le consommateur. Cette étude vise à évaluer les caractéristiques hydrauliques, économiques et biologiques du système et à l’adapter pour la production réussie des poissons jeunes Oreochromis karongae.

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"
