Abstract
The lagoon of Thau is a shallow microtidal system exposed to terrestrial and marine influences. The residence time and the vertical mixing of water-mass are controlled by winds. Periodical absence of wind in Summer can lead to strong anoxia in sediments and bottom waters. Moreover, low inorganic nitrogen and chlorophyll-a levels confer seasonal oligotrophic features to the ecosystem. Nevertheless, a large productive stock of oysters (Crassostrea gigas) cultivated on suspended lines and colonized by epibiota (invertebrates, algae, etc...) covers 20 % of the total area. The aim of the present programme (OXYTHAU 1991–1995) is to study effects of oyster farming on the environment of the lagoon of Thau. Preliminary results obtained are presented here.
