The Ria de Faro-Olhao is a branch of the sea on the southern coast of Portugal with many ramifications delimiting small islands of sand or mud. In a direction parallel to the oceanic margin it spreads for nearly 18 km, and perpendicularly for about 6 km. This region is very important because of the great abundance of bivalves such as Tapes decussatus L., Ceratoderma edule L. Poli and some other species. In order to study the richness of the waters several samples were taken throughout the year twice a month, October excepting, at 3 stations. This material was collected simultaneously with sampling at the Tagus and Sado estuaries, the aim of the project being the primary productivity in richest regions of bivalves of the portuguese coasts. The temperature and all the sea water samples were taken at the surface. This is a preliminar study of the region as it was not possible to obtain further samples at more stations over a larger area.
