This study measured concentrations of trace elements (Al, As, Cd, Cu, Fe, Mn, Ni, and Pb) in the muscle pink shrimps (genus Penaeus) from two anthropized estuarine systems Brazil: Guanabara Bay (GB) Sepetiba (SB). Concentrations were highest less SB site, where showed higher assimilation rates that can be explained by their trophic position compared to GB. These results reinforce role food sour...

This paper outlines the consequences of deterritorialization of artisan fishing folk in Sepetiba Bay in the State of Rio de Janeiro on the occupational and health status of this population living in the area. By means of the concept of social determinants in health, it compares the new patterns of growth in the region with the living and occupational health conditions of these workers. This rel...

Fluorescent excitation-emission matrices (FEEM) of the fluorescent dissolved organic matter (FDOM) are widely used for DOM characterization and tracing. In this work, a set of FEEM from sampling campaigns in the Sepetiba Bay (Brazil) was decomposed into independent components using the parallel factor analysis (PARAFAC) algorithm. Four independent components were extracted describing the total ...

Line transect surveys were conducted from August 2002 to July 2003 examine the abundance and distribution of guiana dolphin (Sotalia guianensis) in Sepetiba Bay-Southeast Brazil. A boat-based platform 50 pre-determined line transects used assess population on two main stratum-specific environments bay (entrance interior). total 3,140km surveyed at 12-15km hr–1 good sea conditions (Beaufort 0-2)...

From July 2001 to June 2002, we recorded a total of 2 h 55 min of Tucuxi Dolphin Sotalia fluviatilis vocalizations from Sepetiba Bay, Brazil (22 degrees 35'S-44 degrees 03'W). A total of 3350 whistles were analyzed quantitative and qualitatively and were divided into 124 types, by visual inspection of sonograms. The following parameters were measured: Initial Frequency, Final Frequency, Minimum...

Sex ratio and size structure constitute basic information in assessing reproductive potential and estimating stock size in fish populations. One hundred fifty-one individuals of Micropogonias furnieri caught by experimental otter trawls, in three zones (inner, central, and outer) of Sepetiba Bay between October 1998 and September 1999 were examined. Males outnumbered females (1.3:1.0) in all zo...
