Maturity, age and growth of Oreochromis karongae (Teleostei: cichlidae) in Lake Malawi and Lake Malombe

Abstract: 
Size-at-50% maturity, age and growth, of Oreochromis (Nyasalapia) karongae (‘chambo’) in Lakes Malawi and Malombe were studied. Similar size-at-50% maturity and growth patterns were found for populations in Lake Malawi, but differences were observed for Lake Malombe populations, suggesting that current chambo fisheries management regulations, based on findings from the southern part of Lake Malawi, may be applicable to the central and southern parts of that lake, but not to Lake Malombe.
La maturité de la taille à 50%, l’âge et la croissance des Oreochromis (Nyasalapia) karongae (‘chambo’) dans les lacs Malawi et Malombe ont été étudiés. La maturité de taille à 50% et les modèles de croissance ont été trouvés semblables pour les populations du lac Malawi, mais des différences ont été observées pour des populations du lac Malombe, suggérant que les règlements courants de gestion des pêcheries de chambo, basés sur des résultats de la partie méridionale du lac Malawi, puissent être applicables aux parties centrales et méridionales de ce lac, mais pas au lac Malombe.

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"
