    Description: We identified from bibliographical review and field observations fourty two species composed essentially of molluscs and insects. These animals attack floating plants such as E. crassipes, P. stratiotes and S. molesta. They indifferently consume or destroy the aquatic plants except N. bruchi, N. eichhorniae and S. albiguttalis which specifically attack E. crassipes. N. putchellus, L. guinaicus and P. africana graze preferably P. stratiotes; C. salviniae, C. singularis and P. acuminata consume only Salvinia molesta.

    Description: The gasteropods sampling from roots system of floating plants Pistia striatiotes, Salvinia molesta, Salvinia nymphellula, Eichhornia crassipes, show that those biotopes are not azoic. We collected 18 species of gasteropods. The mapping of the species collected has been realized and permitted to identify three regions and three groups of gasteropods: 1 The gasteropods collected between 5° and 7° South; 2 The gasteropods collected between 8° and 10° North; 3 The widespread gasteropods. The species distribution according to latitude shows that 90% of species are found between 5° and 6° South, 65% between 6° and 7° South, 20% between 7° and 8°, 20% between 8° and 9° and 15% between 9° and 10° North.

    Description: Located in the Gulf of Guinea, with an area of 322 465 km², Cote d’Ivoire (4°30’ and 10°30’N and 2°30’ and 8°30’W) is bounded by the Atlantic Ocean in the south, Liberia in the south east, Guinea in the northwest, Burkina Faso in the north and Ghana in the east. The coast between Liberia and Ghana is about 540 km length. The country is influenced by the Monsoon (humid) and Harmattan (dry) tropical air masses. These two air masses are separated by the intertropical front that influences the local climate. The climate in southern part, including the coast, is humid tropical and characterized by a climate with four seasons: two dry seasons from November to March and from July to August and two rainy seasons from April to June and from September to October. Forests occupy more than half part of the southern part of the country. Littoral savanna vegetation is found south of the lagoons between Port-Bouet and Grand-Bassam. Pre-lagoon savanna is located north of the lagoons in the dense forest of the south. The littoral zone contains different natural habitats, including five lagoon systems, closed lagoons, swamp forests, mangrove forests (mainly by Rhizophora racemosa and Avicennia africana) The continental shelf, with an area of 12 000 km², has two types of bottom sediments, sandy bottoms in the eastern part and rocky bottoms in the western part. The continental shelf is narrow, with a width that varies between 9 and 18 miles, with a mean of 13 miles. Different types of human activities are conducted in the region, notably agriculture, power generation, timber exploitation, sand extraction, and various industries (e.g. petrol and gas). Several ports are located in this region, including the political capital Abidjan.

    Description: Des cartographies par survol aérien ont été réalisées de décembre 1986 à septembre 1989pour décrire l'évolution saisonnière des macrophytes colonisant les eaux de surface du secteur oriental de la lagune Ebrié. Le couvert végétal de ce secteur lagunaire et des lagunes qui lui sont associées est essentiellement constitué de Eichhornia crassipes (jacinthe d'eau). Son expansion saisonnière est favorisée par la dessalure des eaux lagunaires due aux précipitations. Sa migration dans le milieu lagunaire est assurée par la crue du fleuve Comoé. L'ouverture du grau de Bassam a entraîné son élimination temporaire de la zone estuarienne nouvellement crée.

    Description: Cet article présente les résultats d'une étude comparative de trois séries de prélèvements dans la zone proche du canal de Bassam avant, 6 mois et 20 mois après son ouverture en septembre 1987. Les effets constatés sont la diminution de l'abondance et la modification de la composition de la macrofaune benthique. Ces effets semblent de longue durée, sans reprise en ce qui concerne l'espèce la plus abondante, Corbula trigona. Les changements observés dans la structure des peuplements sont dus essentiellement à l'augmentation de la salinité, et à un degré moindre, aux modifications de la nature du sédiment.

    Description: Les résultats des données floristiques recueillies, au cours de deux campagnes, dans le secteur oriental de la lagune Ebrié, 1987 (avant la réouverture de l'embouchure)et en 1988 (après la réouverture de l'embouchure) sont présentés dans ce texte. L'augmentation de la salinité (de 4 à 30%) consécutive à la réouverture de l'embouchure du fleuve Comoé, en septembre 1987 a profondément modifié, qualitativement et quantitativement, les groupements végétaux. Les macrophytes flottants libres ou fixés ont été complètement détruits; la forêt de mangrove constituant essentiellement la seule ceinture hydrophytique des berges lagunaires.

    Description: La croissance des formes primaire (forme colonisatrice) et tertiaire (forme en "tapis dense") de la fougère d'eau Salvinia molesta (Salviniaceae) a été suivie pendant 60 jours dans des récipients de surface de 0.06m2 et contenant de l'eau douce. La croissance en fonction du temps de cette espèce est exponentielle. Les deux formes d'expansion présentent des taux de croissance statistiquement identiques. L'accroissement journalier moyen, exprimé en nombre de feuilles, est égal à 6,40% par jour pour la forme colonisatrice et à 5,90% par jour pour la forme en "tapis dense" avec des temps de doublement moyens équivalents à 10,78+_ 1.08 jours et à 11.64+_ 0,15 jours.

    Description: The results of floristic data collected during two surveys in the eastern region of Ebrié lagoon in 1987 (before the reopening of the inlet) and in 1988 (after the reopening of the inlet) are discussed in this article. Salinity increase (from 4‰ to 30‰) as a result of the reopening in September 1987 of the channel of Comoé river, profoundly modified qualitatively and quantitatively, the plant population. Floating or fixed macrophytes have been completely destroyed. Mangrove forest being the hydrophytic belt of the lagunar rives.
