Morphology of sagitta, lapillus and asteriscus of Patagonian Genidens barbus
Marine and Fishery Sciences, 2022 Otoliths are calcium carbonate structures, deposited as aragonite, located in the inner ear of bony fish. In recent years, they have become a useful tool for the determination of fish species, trophic content, age studies, and the identification of fish

Population structure and habitat connectivity of Genidens genidens (Siluriformes) in tropical and subtropical coasts from Southwestern Atlantic [PDF]
Estuarine, Coastal and Shelf Science, 2020 Abstract 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 presence of different nursery areas and fish stocks of Genidens genidens in the Brazilian coastal area.

Habitat use of the amphidromous catfish Genidens barbus : first insights at its southern distribution limit [PDF]
New Zealand Journal of Marine and Freshwater Research, 2021 ABSTRACT White sea catfish Genidens barbus is an endangered amphidromous species distributed between northeastern Brazil and northern Argentine Patagonia, whose migratory behaviour at the southern end of its range is unknown. Here, the migratory patterns of this species were studied including marine and freshwater (Patagonian stock ...
