The general circulation pattern in the western boundary of the SW Atlantic is dominated by the opposite flows of Malvinas (-Falkland)and Brazil Current. In the Confluence region both currents separate from the continental slope and flow offshore creating an area of strong contracts and complex dynamics. The shelf-break fronts off Argentina mark the transition between shelf waters of mixed origin and nutrient rich Malvinas waters. Two areas deserve special attention due to the steep gradients introduced by the outflow of important sources of continental waters: the Rio de la Plata and the Magellan Strait to the north and south of the study area. Characteristics of the front is the high primary and secondary production, and the presence of important invertebrate and fish stocks that concentrate along the front to feed or spawn. The area comprises nearly 30 o/o (333 million U$S in 1995)of all Argentine catches of fish and squid. Resources in the area, beyond the EEZ limits, support international fisheries mainly of Russia, Poland and Spain. (Document contains 15 pages & figs)

Between 1981 and 1995, we published five bibliographic lists (López et al., 1981, 1982,1987, 1989 y 1995) that included the publications referred to Argentine freshwater fishes and related general information published since Ringuelet et al. (1967). We included Uruguayan papers until 1989, when it became apparent that our access to those materials was not complete. Other bibliographic collections were published on several subjects (López et al., 1991, 1993, y Ferriz et al., 1998). In the foreword to the 1995 list, López stated that it was difficult to assess the actual usefulness of the lists, since they were seldom quoted in research papers. This consideration, along with the wide success of electronic databases, caused us to discontinue the series, since its only goal had been to increase the knowledge and access to local research papers and foreign publications of interest to local researchers. Regrettably, our experience indicates that access to scientific literature is still, if not difficult, somewhat arbitrary. Apart from that, the continuous work on diverse research lines at División Zoología Vertebrados of Museo de La Plata leads to the accumulation of a multiplicity of information which may be sorted out for the use of others without much difficulty. At present, electronically-supported databases appear as the simplest way to do this. The future will show if this method is more efficient than the preceding one. In this issue we have included papers published between 1996 and 2002; and it is our purpose to update the list on a yearly basis. Papers included cover Argentine fish fauna and some related subjects of more general interest. Naturally, it is hardly surprising that some involuntary omissions will occur when addressing this subject. Any corrections and/or additions will be incorporated in following versions; and all information is most welcome.
