Previous meristic analysis of the oblique scale counts (OSC) of Mugil liza showed a bimodal
pattern within the southern stock, between São Paulo, Brazil (− 24° S), and Samborombón …

The dentification of nursery areas is a basic requirement for fishing management in large

Trace element: Ca (Ba: Ca, Mg: Ca, Mn: Ca and Sr: Ca) ratios in water and last growth
intervals (outer 45 µm) of dorsal spine and otolith edges from Genidens barbus collected in …

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 …

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 …
