Food type preference, Breeding Seasonality and size at first Maturity of Synodontis njassae of Southeast arm of Lake Malawi

Abstract: 
The food type preferencein the southeast arm of Lake Malawi was studied. Frequency of occurrence, gravimetric, volumetric and index of relative importance was used to assess food preference. It was found that S. njassae is an omnivore, consuming a range of aquatic insects, detritus, phytoplankton’s and other fish. Therefore, this species may accept a wide range of formulated diets that contains ingredients derived from plants, aquatic macro-invertebrates or animals. This makes the culturing of this species in captivity potentially possible.
La préférence de type d’aliment dans le bras Sud-Est du lac Malawi a été étudiée. La fréquence de l’événement, gravimétrique, volumétrique et l’indice de l’importance relative ont été utilisés pour évaluer la préférence alimentaire. Il a été constaté que S. njassaeis un omnivore, consomme une variété d’insectes aquatiques, des détritus, du phytoplancton et d’autres poissons. Par conséquent, cette espèce peut accepter un large éventail de régimes alimentaires formulés qui contient des ingrédients dérivés de plantes, de macro-invertébrés aquatiques ou d’animaux. Cela rend la mise en culture de cette espèce en captivité potentiellement possible.

The 2012 RUFORUM Biennial Conference is the third 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 stakeholers 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. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Harnessing Aquaculture and Fisheries
