Feeding habits and behaviour of Bagre bagre and Genidens barbus, two ariid catfishes (Pisces: Siluriformes) from southeastern Brazil

Journal of Threatened Taxa, 2017
The feeding habits and behaviour of adult specimens of Bagre bagre (Linnaeus, 1766) and Genidens barbus (Lacepède, 1803), both targets of commercial fisheries in coastal southeastern Brazil, were evaluated through stomach content analysis.  These catfish

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

Estuarine, Coastal and Shelf Science, 2021
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 ...

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 (Paranagua estuarine complex ...

Virulence-Associated Genes and Antimicrobial Resistance of Aeromonas hydrophila Isolates from Animal, Food, and Human Sources in Brazil. [PDF]

Biomed Res Int, 2020
Aeromonads are natural inhabitants of aquatic environments and may be associated with various human or animal diseases. Its pathogenicity is complex and multifactorial and is associated with many virulence factors. In this study, 110 selected Aeromonas hydrophila isolates isolated from food, animals, and human clinical material from 2010 to 2015 were ...

Cytogenetic analysis of three sea catfish species (Teleostei, Siluriformes, Ariidae) with the first report of Ag-NOR in this fish family [PDF]

Genetics and Molecular Biology, 2010
Despite their ecological and economical importance, fishes of the family Ariidae are still genetically and cytogenetically poorly studied. Among the 133 known species of ariids, only eight have been karyotyped.

Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil. [PDF]

Evid Based Complement Alternat Med, 2017
The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at
