Régime alimentaire de <i>Pomadasys jubelini</i> (Pisces, Haemulidae) dans une lagune Ouest africaine (lagune Ebrié, Côte d\'Ivoire)

Abstract: RésuméLa description de la morphologie du tube digestif des poissons a permis de mettre en évidence chez Pomadasys jubelini (Cuvier, 1830) un estomac développé et un intestin relativement court. Le coefficient intestinal, relativement bas (0,70 < CI < 1,43 pour des poissons dont la longueur standard est comprise entre 75 et 225 mm), a permis de rapprocher cette espèce de la catégorie des poissons omnivores. L'analyse des contenus stomacaux de 318 spécimens de P. jubelini capturés a confirmé le régime omnivore … Show more

“…Dietary variation in a given species may be related among other to the level of development or differentiation of the digestive system (Legendre, 1992) and the habitat exploited (Lowe-McConnell, 1975). The similarity noticed among diet of different size specimens and perhaps different maturity stage in the present study could be due to the fact that they are caught in the same habitats, the formation (or differentiation) of the digestive system of individuals from all size encountered is already completed, hence they have similar abilities to exploit the same resources (Koné, 2007).…”

“…Furthermore, the low intestinal coefficient confirms that species belongs to the group of omnivorous fishes as already noted by Fryer & Iles (), Paugy () and Koné et al . (). Fish scales were also found in the diet of S .…”

“…Chez Ethmalosa fimbriata et Pomadasys jubelini, les sujets n'atteignent pas la taille commerciale ce qui pourrait s'expliquer par la faible diversité de leur régime alimentaire et du partage des phytoplanctons avec les autres espèces de poissons. Toutefois, le régime alimentaire identifié chez Pomadasys jubelini confirme la présence de larves de Chironomidae et de restes d'insectes dans le suc stomacal de spécimens capturés dans la lagune Ebrié en Côte d'Ivoire(Koné et al, 2007). Chez Sarotherodon melanotheron et…”
