Articulo Icthyological study from the port of Buenos Aires city Biología Acuática; no. 19 The port of Buenos Aires is located in the Rio de la Plata river on the riverside of the homonymous city. The fish community that inhabits the port water’s was studied in order to know the specific composition, relative abundance, spatial distribution and its relationships with the port activities. Ten sampling places were considered, seven inside the port and three in the access channels. The sampling was realised on August and September of 1998, using active and passive fishing gears. Diversity indices, Margalef' (Rl) and Shannon and Weaver (HO, were calculated. A cluster analysis was carried out with relative abundance of each taxa. In access channels, four species were captured and its relative abundance and diversity were similar for each stations. Contrarily inside the port twenty-seven species was registered, the relative abundance and specific composition were more fluctuate than out side. The heterogeneity observed in the distribution of the fish community would be linked to the design of the port and the activities that are developed in each place.

Articulo Diversity of benthic invertebrates of the Río de la Plata river Biología Acuática; no. 19 The Rio de la Plata river present along the south coastal fringe different invertebrate assemblages related with substrate type, size sediment grains and organic matter content into the bedsediments. Other important factors influencing the distribution of benthos community in this river are the salinity and suspended solids of the water and the proximity to the riverside which increases the diversity of the habitats. The purpose of this study is to describe the taxonomic composition and ecological characteristics of the meso and macrobenthos associated with the river bed from Delta del Paraná to Magdalena, in Buenos Aires province. The listed taxa are the result of the revised literature and original data obtained from periodical samplings since 1993 till 1998. The principal components of the zoobenthos in the studied area were the allochthonous molluscs Corbicula fluminea on sandy and muddy bottoms and Limnoperna fortunei on hard substrates of the riverside. The nematods and oligochaetes dominated sediments with high allochthonous organic matter content imported from urban effluents. Palaemonetes argentinus, Macrobrachium borelli, Claudicuma platensis, Sinelobus stanfordi, Basphaeroma rhonbofrontale and Trichodactylus panoplus were the more common crustaceans in non polluted areas.

Articulo Phytoplankton diversity from the Southern Coastal Fringe of the Río de la Plata Biología Acuática; no. 19 Diversity of phytoplankton from the Southern Coastal Fringe of the Rio de la Plata between 58°32' and 57°41' W, up to 10 km from the coast line was analized. The present study show the results of the sampling carried outside peces between 1993-1997. The species identified were illustrated and a brief ecological and meristic description was done for each taxon. A total of 211 samples were analysed and 172 taxa were found. The phytoplankton structure showed the predominance of few species and the highest diversity was located near the coast. The green algae and the diatoms were frequents and sometime the most abundant groups. Suspend solids carried by the river, stational and climatic changes and antropic disturbance are the most important factors in phytoplankton development. A few brachish-water or marine species have been found in the zone studied. According to ecological features the phytoplankton analysed was eutrophic, oligohalophilous and mesosaprobic.

Articulo Biología Acuática; no. 19 El objetivo de esta contribución es hacer hincapié en la diversidad del fitoplancton y del zoobentos de la Franja Costera Sur del Río de la Plata correspondientes a las campañas embarcadas iniciadas a partir de 1993 en forma conjunta con el Servicio de Hidrografía Naval de la Armada Argentina (SHN), la Administración General de Obras Sanitarias de la Provincia de Buenos Aires (AGOSBA), Aguas Argentinas (AA) y el Instituto de Limnología “Dr. Raúl A. Ringuelet” (ILPLA). Estas campañas permitieron relevar información del área comprendida entre los 0.5 y 10 km de la costa, entre las localidades de San Fernando y Magdalena. También, se incluye un estudio intensivo sobre la ictiofauna del puerto de la ciudad de Buenos Aires y en el caso del zoobentos se incorporó información adicional de los taxa mencionados en otros estudios realizados en áreas aledañas a la ribera bonaerense.
