The Uruguayan industrial fleet was formed by 33 otter board and pair trawlers from 19 to 33 m long in 2003, and had the species as one of its main targets along the northern margin of the La Plata River Estuary and Uruguayan Atlantic coast (Norbis et al, 2006).
As major spawning and nursery grounds exist the La Plata River Estuary in the AUCFZ and in the Los Patos Lagoon Estuary in southern Brazil it is not likely that intense fishing in any of these regions lead to the collapse of the fishery in the other.
The Bonaerense Lower delta islands are formed by the accretion of silts transported and deposited by the Paraná river in the de la Plata river.
Unit B, downstream from A and locally referred to as forest nucleus, has a transitional hydrology between the fluvial influence of the Paraná river and the tidal influence of the de la Plata river.
Nonetheless, the BLBP's riverine export of nitrogen is in accordance with values observed when the nitrogen export by La Plata River near Buenos Aires, Argentina, is accounted.
2002) suggest that increasing nutrient loads of nitrogen and phosphorus and the low potential to dilute nutrients by La Plata River may aggravate eutrophication conditions like oxygen stress and harmful blooms in coastal zones.
Key words: ectoparasites, host sex, Scapteromys aquaticus, water rat, La Plata river marshland, Argentina.
The subject of the present study is to analyze the interrelationship between host sex and the infestation with ectoparasites in La Plata river marshland.
Los Ajos is part of the La Plata River

The Island of Martin Garcia is located in the Upper Rio de La Plata River
, to the South of the mouth of the Uruguay River (34[degrees]11'09"S and 58[degrees]15'09"W).
The leech fauna of Martin Garcia Island ponds does not differ markedly from that found on a beach of Rio de la Plata river
and in a steady pond near the coast of the same river (Gullo and Darrigran, 1991; Darrigran et al.
piscium as a freshwater species, Darrigran (1995) also considers it euryhaline enough to occur in zones of the Rio de la Plata river
with changes in the salinity of the water between 0.
