Abstract The concentration of Ag, As, Cd, Cu, Cr, Hg, Ni, Pb, Se, U, V, and Zn was analyzed
in water, sediment, and different organs of Prochilodus lineatus (muscle, liver and gill) in …

Estuarine fish research in South America began in the early 20th Century, but it is only within
the last 40 years that detailed studies have been undertaken. This review firstly summarizes …

The dentification of nursery areas is a basic requirement for fishing management in large
rivers. Morphometry (circularity, ellipticity, form factor, rectangularity and roundness indices) …

Many reef fishes move between different coastal systems throughout their ontogeny, but
these movements are complex and often not understood. In this study, we examined how the …

Catfish Genidens barbus is a commercially fished species from the south-western Atlantic
Ocean. Overfishing of this species during the last few years has caused a collapse of …

We use otolith trace element-to-calcium element concentraton ratios (Ba: Ca, Cu: Ca, Mg:
Ca, Mn: Ca, Ni: Ca, Sr: Ca and Zn: Ca) and shape to evaluate the degree of segregation and …

To use elements as salinity proxies, relationships of elemental concentrations with salinity
must be known and vary from freshwater to marine endmembers. To extend these proxies to …
