The study aims to discriminate juvenile and adult concentration areas of white croacker Micropogonias furnieri and striped weakfish Cynoscion striatus in two different areas: Argentine-Uruguayan Common Fishing Zone (AUCFZ) and El Rincón (Buenos Aires Prov., Argentina). The length structure and the relative abundance of these two species were analyzed with data from a research cruise carried out by R/V Dr.E.L.Holmberg during November 1994. Data of relative abundance in t/nm2 were considered to define distribution and concentration areas. 49 samples of white croaker and 41 striped weakfish from AUCFZ a, inside the area of Río de la Plata and in front of Montevideo coast, at depths lesser than 8 meters, while the adults were located in the northern coast of Uruguay, at depths greater than 20 meters. The density of white croaker oscillated between 0.7 and 8 t/nm2 and juveniles were absent in El Rincón. The most important concentration area of striped weakfish extends from Punta del Este to.....
