| L'algue d'origine japonaise Sargassum muticum (Phaeophyceae, Fucales) est maintenant bien établie dans l'Etang de Thau, à la suite de l'importation de naissain de l'huitre japonaise Crassostrea gigas. S. muticum vit fixé sur des substrats durs (roche, pierres, coquilles, cordes). Malgré les apparences, la biomasse de S. muticum est relativement modérée, si on la compare avec celle de certaines grandes Phaeophyceae méditerranéennes ou atlantiques. Des individus libres, la ramification du tronc (chez des individus âgés) la formation de nouvelles tiges dressées (à aspect de germinations) à partir de proliférations des crampons, et des thalles cespiteux, sont des caractères originaux qui caractérisent peut-être les populations de l'Etang de Thau.

| Study of soft substrate macrophytobenthos from the mediterranean Thau lagoon has been carried out as a part of the ECOTHAU research program. All soft substrates have been sampled in autumn 1986. Data analysis is based on cartography, total and main species biomass assessment, as well as study of phytobenthos differentiation factors. Vegetation seasonality was analysed from october 1985 to october 1986 in the East area (shellfish breeding zone and "Eaux blanches" lagoon). The hydrologic and topographic characteristics give to vegetation a high specific richness (74 macrophytes on soft substrates and a total of 167 taxa for the lagoon). Compared to those of other mediterranean lagoons, the Thau phytobenthos appears to be original and diversified. This... |
