Nursery areas and connectivity of the adults anadromous catfish (Genidens barbus) revealed by otolith-core microchemistry in the south-western Atlantic Ocean

Marine and Freshwater Research, 2017
The anadromous catfish, Genidens barbus, is a commercial and vulnerable species from South America. The aims of the present study were to assess whether the nursery areas can be discriminated by using microchemical signatures of lapillus otoliths, to ...

New records of anadromous catfish Genidens barbus (Lacépède, 1803) in the Paraná Delta (South America): evidence of extension in the migration corridor?

Marine Biodiversity Records, 2015
The catfish Genidens barbus (Siluriformes: Ariidae) is an anadromous species from South America. It has been classified as vulnerable in Argentina and Uruguay due to its complex life cycle, its restricted distribution in fresh or estuarine waters and the critical levels of fishery harvesting of this species. In this work, we report the occurrence of

Revealing the drivers of taxonomic and functional diversity of nearshore fish assemblages: Implications for conservation priorities

Diversity and Distributions, Volume 28, Issue 8, Page 1597-1609, August 2022., 2022
Abstract Aim Understanding patterns and drivers of biodiversity are essential towards developing effective conservation strategies for shallow marine habitats broadly. However, little is known about the natural and anthropogenic factors that structure fish biodiversity of sandy beaches, one of the largest and most socio‐economically valuable nearshore ...

Carbon primary sources and estuarine habitat use by two congeneric ariid catfishes in a subtropical coastal lagoon

Zoologia (Curitiba), 2016
Although ariid catfishe species are known to use coastal systems during some stages of their life cycles, the energetic contribution of estuarine resources and habitat use by many species in this family are still unclear.
