Inter-annual variability in otolith chemistry of catfish Genidens barbus from South-western Atlantic estuaries

Journal of the Marine Biological Association of the United Kingdom, 2017
The catfish Genidens barbus is a commercial species from South America. The aim of the present study was to examine the inter-annual variability in estuary-specific chemical signatures of otolith cores (Ba:Ca, Mg:Ca, Mn:Ca, Sr:Ca and Zn:Ca ratios) for three estuaries from Argentina and Brazil where adults were collected over multiple years. Secondarily,
