THE FIRST REPORT OF ABNORMAL AGE RINGS IN OTOLITHS LAPILLUS OF ARIIDS CATFISH
Boletim do Instituto de Pesca, 2021 The present work aimed to record the first presence of abnormal age rings in Cathorops spixii lapillus otoliths from Cananeia-Iguape Estuarine-Lagoon Complex (CIELC), Southern region of Brazilian coast. In August 2018, 59 specimens of C.

Complex patterns of genetic population structure in the mouthbrooding marine catfish, Bagre marinus, in the Gulf of Mexico and U.S. Atlantic. [PDF]
Ecol EvolAbstract Patterns of genetic variation reflect interactions among microevolutionary forces that vary in strength with changing demography. Here, patterns of variation within and among samples of the mouthbrooding gafftopsail catfish (Bagre marinus, Family Ariidae) captured in the U.S.

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

DNA barcoding of marine rocky reef fishes from northern Peru suggests a parapatric speciation in the Tropical Eastern Pacific. [PDF]
Ecol EvolUsing a DNA barcoding technique we found evidence that reinforce the hypotheses of how parapatric speciation could drive the origin of new species in the TEP. Abstract Northern Peru marks the end of an extensive coastal marine region: The Panama province, which is characterized by predominantly tropical and equatorial features and is home to the only ...

The complete mitochondrial genome of Arius arius (Siluriformes: Ariidae). [PDF]
Mitochondrial DNA B Resour, 2016 The threadfin sea catfish (Arius arius) belongs to the genus Arius in Ariidae. In this paper, we initially determined the complete mitochondrial genome of Arius arius. The mitochondrial genome is 16, 711 bp in length, with the base composition on the heavy strand: A - 29.67%, T - 25.38%, C - 29.70% and G - 15.25%.

Fish otoliths from the middle Miocene Pebas Formation of the Peruvian Amazon
Swiss Journal of Palaeontology, 2022 A small assemblage of 22 otoliths was identified from the historical collection of Bluntschli and Peyer gathered in 1912 on the Itaya riverbank at Iquitos, Peru (Amazonia), from the Pebas Formation.
