The objective of this study was to analyze and compare the diet of four Marcusenius species living in the Malebo Pool. The Intestinal Coefficient of these fish ranges from 0.55 to 0.67. These average values make it possible to classify these species in the trophic group of invertivores (larvae of aquatic insects). The analysis of variance at the 5% threshold reveals that there is not a statistically significant difference between the average intestinal coefficients of 4 species of Marcusenius (Fischer = 2.46963; p = 0.06). stomach contents of M. monteiri, M. stanleyanus, M. schilthuisiae and M. sp.'malebo' confirm an invertivorous diet, with a predominance of benthic insect larvae, followed by crustaceans, periphyton and macrocosm organisms benthic that they find in their habitats.

Mormyridae fish, which make up 20 to 25% of the catches in the Malebo Pool, are subject to pressure from local fishermen. This pressure on the resource is the basis of the decrease in catches, which has an impact on the social situation of the people involved in the sector. The objective of this study is to evaluate the exploitation of Mormyridae fish in the Malebo Pool and to propose conservation measures for sustainable management. The data was collected using the survey method with the interview technique. The results obtained confirm overfishing with a decrease in catches, which has consequences on the social situation of fishermen, fishmongers, processors and consumers. Thus, in order to reduce overfishing to a sustainable exploitation, co-management between the manager and the stakeholders, compliance with regulations, awareness raising and training in conservation and sustainable exploitation based on a series of biological and socioeconomic indicators accepted by all stakeholders are necessary.
