Prologue to coastal demersal resources evaluation survey in the Buenos Aires Province and the Uruguayan littoral. November, 1994. The Coastal Project developed at the INIDEP (Mar del Plata,Argentina) offers an analysis on the operative modality of coastal assessment surveys, proposing an information process useful to standardize data collection and processes of future surveys. The efficiency of the evaluation of strata used until the year 1993 was analyzed and a new stratification is proposed. The aim was to define area-strata of importance for the main coastal species, using the traditional stratification of the coastal ecosystem and the mew methodology. The reason for redefining strata is that a decrease was been detected in the number of traditional species and an increment on the biomass of non-commercial species and,associated with it, the development of new explotation areas. The analysis of the physical environment of the coastal ecosystem includes aspects of the biology of such species and the distribution of reproductive concentrations, nursery and spawning areas, due in part to oceanographic structures like thermal, saline frontsand turbidity. The dynamics of coastal resources considering two different oceanographic areas with different types of fishing administration and different levels of fishing effort, are described. These two areas are: The Argentine Uruguayan Common Fishing Zone(AUCFZ), influenced by the Río de la Plata, and the area of El Rincón, of marine waters. In the area influenced by the estuary of the Río de la Plata the coastal fleets of Uruguay and Argentina carried out jointly commercial fishing activities; this area is administrated by the Administrating Commission of the Río de la Plata (ACRP) and the Mixed Technical Commission of the Marine Front(MTCMF) by means of the AUCFZ. In the area of El Rincón the only fishing fleet is Argentine and it is administrated by the Secretariat of Agriculture,Livestock, Fisheries and Food.
