Fin spine metals by LA-ICP-MS as a method for fish stock discrimination of Genidens barbus in anthropized estuaries [PDF]

Fisheries Research, 2020
Metal:Ca ratios (Li:Ca, Cu:Ca, Fe:Ca, Na:Ca, Rb:Ca, Pb:Ca and Zn:Ca) in fin spines of Genidens barbus, an endangered catfish species, were used as possible habitat markers from three Southwestern Atlantic sampling areas (Paranaguá estuarine complex ...

Microplastics in vulnerable catfish: baseline data from northern Patagonia’s Genidens barbus

Regional Studies in Marine Science
Microplastics (MPs) contamination in aquatic ecosystems poses a rising environmental challenge with impacts on biota. This study provides the first assessment of MPs ingestion by the vulnerable Genidens barbus (white sea catfish) species in northern ...

El bagre marino (Genidens barbus) en el estuario del río Chubut: Un nuevo registro en la costa Patagónica Argentina

Gayana
El bagre marino (Genidens barbus) es una especie anádroma de Sudamérica, que se distribuye desde Brasil hasta Argentina. Se considera vulnerable por su baja fecundidad e incubación oral en machos, que migran a los estuarios para reproducirse.

First report of Genidens barbus during the non-reproductive period in coastal waters of Río Negro, Argentina

Marine and Fishery Sciences
The marine catfish Genidens barbus is a benthic and anadromous species distributed from Brazil to southern Argentina. Its presence during the non-reproductive period remains poorly documented. This study reported the first confirmed record of a female G.

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 ...

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 ...

Integrated use of otolith shape and microchemistry to assess Genidens barbus fish stock structure

Estuarine, Coastal and Shelf Science, 2021
Abstract Otolith composition (edge vs core: Mg/Ca, Mn/Ca, Zn/Ca, Sr/Ca, Ba/Ca) by LA-ICP-MS and Elliptic Fourier analysis were integrated to evaluate spatial segregation of adult and juvenile stages of Genidens barbus from specimens collected from five coastal areas off Brazil (Paraiba do Sul River, Guanabara Bay, Itapanhau River mouth, Paranagua Bay)

Fish biodiversity of a tropical estuary under severe anthropic pressure (Doce River, Brazil)

Neotropical Ichthyology, 2022
The Doce River has undergone severe changes over the last centuries (e.g., flow regulation, pollution, habitat and species loss). Here, we present the first comprehensive fish biodiversity assessment of the Doce River estuary and a summary of the main ...

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.
