Última Seasonal abundance of the Neotropic Cormorant (Phalacrocorax brasilianus) at Lagoa dos Patos estuary, Southern Brazil Hornero Barquete,Viviane; Vooren,Carolus Maria; Bugoni,Leandro. Censuses of the Neotropic Cormorant (Phalacrocorax brasilianus) were carried out at a power tower near the mouth of Lagoa dos Patos estuary, southern Brazil, from November 2001 to October 2002. At this major roosting site, a total of 309 counts over 47 days of census were performed to estimate monthly variation in the abundance of the Neotropic Cormorant. The highest abundance occurred in January (1390 birds), and the lowest in May (117 birds). The tower was a roosting site for cormorants at night, which arrived around 15:30 h onward, with numbers increasing near dusk. Birds preferentially used the lower levels of the tower (including the concrete base and levels 1 and 2) throughout the year and this preference could be partially due to strong winds in the...

A total of 459 individuals of Atlantoraja cyclophora were captured along the Rio Grande do Sul coast between latitudes 30º40'S and 34º30'S. Two surveys were performed, in the winter 2001 and in the summer/autumn 2002, using bottom-trawl between the depths of 100 and 600 m. This species occurred between 100 and 300 m deep, without significant differences in the frequency of occurrence and abundance (CPUE; kg/hour) between latitudes, depth and seasons. The sex ratio was not significantly different from 1:1 in all depths. In the study area, temperature ranged between 10.0 ºC and 17.6 ºC and salinity between 35.2 e 36.0 ppm. There was no correlation between CPUE and depth, temperature and salinity. Mean total length of females (53.2 cm) was significantly...
