Diet of three juvenile fish species of the coastal zone of a Southwest Atlantic beach, Brazil

open access: yesActa Scientiarum: Biological Sciences, 2022
Surf zones are associated with a shelter area, nursery and feeding for several species of fish. In this study, the dietary habits of three species of fish with demersal habits (Gulf kingcroaker Menticirrhu gracilis, Whitesea catfish Genidens barbus and ...

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

open access: yesDiversity 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

open access: yesEstuarine, 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)

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

open access: yesFisheries Research, 2020
Abstract 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, Brazil; Parana River Delta, Argentina-Uruguay; and Negro River, Patagonia).

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

open access: yesNeotropical 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 ...

Nycthemeral and Monthly Occupation of the Fish Assemblage on a Sheltered Beach of Baía Norte, Florianópolis, Santa Catarina State, Brazil [PDF]

open access: yes, 2014
A interpretação dos registros da comunidade ictíica têm se mostrado um desafio por diversos motivos, entre eles a falta de dados pretéritos, existência de variações temporais cíclicas na comunidade e pelos métodos utilizados que geralmente subamostram a ...

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

open access: yesZoologia (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.

Peixes ósseos (Teleostei) capturados pela pesca de pequena escala na costa centro-sul de São Paulo, Sudeste do Brasil [PDF]

open access: yes, 2014
Small-scale fisheries have a great socioeconomic importance in Brazil. Different regional characteristics along the coast, mostly related to landing sites, equipment used, and targeted species, renders its assessment and monitoring difficult.

Population structure and habitat connectivity of Genidens genidens (Siluriformes) in tropical and subtropical coasts from Southwestern Atlantic [PDF]

open access: yes, 2020
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 ...
