Study of the diet and feeding habits of 104 specimens of Liza dumerili (Steindachner, 1870) and 113 specimens of Liza falcipinnis (Valenciennes, 1836) coming from the artisanal fishing of the Grand-Lahou lagoon was carried out over the period from September 2008 to August 2009. Analysis of stomach contents revealed that these two species of fish feed mainly on diatoms and detritus. It appears that these species are phytoplanktonophagous and detritivores. The diet of Liza falcipinnis does not vary according to the size of the individuals. These two species specialize in the consumption of diatoms, particularly pennate diatoms.

The diet of 400 specimens of Cardium costatum from the exclusive economic zone of Côte d'Ivoire was studied for two years depending on the hydrological seasons and the size of the individuals. Stomach contents were analyzed using frequency of occurrence, numerical frequency, and specific abundance methods. The results obtained show that this bivalve is a planktophagus and also feeds on inert organic matter (detritus) and bacteria. Phytoplankton forms the major constituent of its diet regardless of season and size. However, most immature young people have a specialist feeding strategy for Navicula and mature ones prefer Amphora.

Abstract Bahou, L., Koné, T., N'Douba, V., N'Guessan, K. J., Kouamélan, E. P., and Gouli, G. B. 2007. Food composition and feeding habits of little tunny (Euthynnus alletteratus) in continental shelf waters of Côte d'Ivoire (West Africa). – ICES Journal of Marine Science, 64: 1044–1052. The stomach contents of 170 little tunny, Euthynnus alletteratus, sampled between June 2003 and December 2004 were examined. Fish size ranged from 27 to 81 cm fork length, and all fish were caught in gillnets deployed over the continental shelf off Côte d'Ivoire (West Africa). The type and quantity of prey ingested changed seasonally. Outside the major upwelling period the diet was more varied. Overall, fish were the dominant prey of all sizes of little tunny, far exceeding crustaceans, of which shrimps and prawns were commonest but were not found in the stomachs of juveniles (<42 cm FL) or larger adults (≥53 cm FL). Little tunny are carnivorous fish that feed opportunistically. A relationship was found between the size of the prey and the size of the predator.

Mesures Correctives

Considéré comme une véritable source d’espoir pour promouvoir la pêche artisanale en Côte d’Ivoire, le débarcadère de Locodro baptisé « Point de débarquement Mohammed VI » reste encore loin de répondre à cette attente après son ouverture en juin 2018. Cette situation suscite plusieurs interrogations sur les difficultés auxquelles il est confronté vu les commodités qu’il comporte pour être un excellent centre d’approvisionnement en produits halieutiques. Cette étude permet donc d’identifier ces difficultés, de montrer leurs conséquences sur la vie socio-économique des acteurs et de faire des recommandations pour la bonne marche dudit débarcadère. Pour la collecte des données, des documents traitant des thèmes en rapport avec la pêche ont été consultés. En plus, une enquête a été réalisée par le biais d’un questionnaire et des entretiens. Les résultats ont montré que les difficultés qui entravent le bon fonctionnement du débarcadère sont principalement liées à sa délocalisation d’Abobo-Doumé à Locodjro. Ces difficultés impactent négativement la vie socio-économique des acteurs. Cette situation qui suscite des inquiétudes recommande que des mesures correctives soient prises avec l’implication de toutes les parties concernées pour une rentabilité durable du débarcadère au profit de tous. Considered as a real source of hope to promote artisanal fishing in Côte d'Ivoire, the landing stage of Locodro named "Mohammed VI Landing Point" is still far from meeting this expectation after its opening in June 2018. This situation raises several questions about the difficulties it faces given the amenities it has to be an excellent supply centre for fishery products. This study therefore makes it possible to identify these difficulties, to show their consequences on the socio-economic life of the actors and to make recommendations for the good functioning of the said landing stage. For the collection of data, documents dealing with themes related to fishing were consulted. In addition, a survey was carried out by means of a questionnaire and interviews. The results showed that the difficulties hindering the proper functioning of the landing stage are mainly related to its relocation from Abobo-Doumé to Locodjro. These difficulties have a negative impact on the socio-economic life of the stakeholders. This situation, which gives rise to concern, recommends that corrective measures be taken with the involvement of all the parties concerned for a sustainable profitability of the landing stage for the benefit of all. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0896/a.php" alt="Hit counter" /></p>

Coptodon hybride est un poisson issu des croisements naturels entre Coptodon zillii X Coptodon guineensis. La présente étude a pour objectif de caractériser les habitudes et les stratégies alimentaires de ce poisson, en fonction de la taille des individus, des stations d’échantillonnage et des saisons hydrologiques dans la lagune Ebrié (Côte d’Ivoire). Sur un total de 323 individus (65< longueur standard ≤ 225 mm) capturés d’août 2014 à juillet 2015 avec des filets maillants, 236 tubes digestifs contenaient des proies et 87 étaient vides (26,93%). L’Indice d’Importance Relative (%IRI) qui prend en compte les pourcentages d’occurrence, numérique et pondérale, a été utilisé pour évaluer l’importance relative des différentes catégories de proies dans les tubes digestifs. Cinq groupes de proies ont été identifiés : insectes, zooplancton, crustacés, phytoplancton et plantes terrestres. Le régime alimentaire de Coptodon hybride est essentiellement constitué de plantes terrestres, surtout de débris végétaux (91,53% de l’IRI). L’analyse du coefficient de corrélation de Spearman montre une variation du régime en fonction de la taille et des stations. Cependant, il n’y a pas d’influences significatives des saisons sur l’alimentation des individus de petites tailles (65-129 mm) et ceux de grandes tailles  (130-225 mm).Mots clés: Habitudes alimentaires, Coptodon hybride, lagune Ebrié, Côte d’Ivoire. English Title: Feeding habits of hybrid Coptodon resulting from natural crosses between Coptodon zillii (Gervais, 1848) and Coptodon guineensis (Bleeker, 1862) in the Ebrié lagoon (Côte d'Ivoire)Hybrid Coptodon is a fish resulting from natural crosses between Coptodon zillii X Coptodon guineensis. The objective of this study is to characterize the feeding habits of this fish, according to the size of individuals, sampling sites and hydrological seasons in the Ebrié lagoon (Côte d'Ivoire). A total of 323 specimens (65< standard length ≤ 225 mm) were captured from August 2014 to July 2015 with gillnets. hundred and thirty-six digestive tracts contained prey and 87 were empty (26.93%). The Relative Index (%IRI), including the occurrence, numerical and weight percentages, was used to assess the importance of the different categories of prey in the digestive tract. Five groups of prey have been insects, zooplankton, crustaceans, phytoplankton and terrestrial plants. The hybrid tilapia’s diet shows terrestrial plants and plant debris (91.53% of IRI). The Spearman correlation coefficient analysis variations as a function of size and sample sites. However, there are no significant seasonal influences diet of small (65-129 mm) and large (130-225 mm) fish.Keywords: Feeding habits, hybrid Coptodon, Ebrié lagoon, Côte d’Ivoire.

Food And Feeding

Food and feeding behavior of P. leonensis was studied by analyzing the stomach contents of 864 individuals caught in the two main catchment areas in Taabo Lake, notably, at Taabo city and Antonio. Food items data were analyzed by using the three following methods: Relative Importance Index (IRI), Food Index of Geistdoerfer (Q) and Principal Component Analysis of Occurrence Index. The results of our study showed, that P . leonensis is zooplanktonophagus. Its diet also includes Diptera (Ceratopogonidae, Chaoboridae), Ephemeroptera (Baetidae, Libellulidae), Trichoptera and Hymenoptera (Formicidae). The Food Index of Geistdoerfer indicates, that the diet of this Fish species is composed of two main preferential preys: Copepods and Cladocerans. Furthermore, Chironomidae are frequent secondary preys and the others items are secondary order complementary preys. At least, the results of the principal component analysis of items occurrences show, that the prey frequency is function of P. leonensis catchment area or sub-area in Taabo Lake, and evolve inversely, according to climatic seasons. © 2019 International Formulae Group.
