Lapillus otoliths of the Cathorops spixii (Spix & Agassiz, 1829) and Genidens genidens (Cuvier, 1829) (Actinopterygii - Ariidae) [PDF]
Acta Scientiarum: Biological Sciences, 2014 The aim of this study was to analyze the morphology and morphometry of lapillus otoliths of the catfishes Cathorops spixii and Genidens genidens from the coast of Paraná State, Brazil. We used 147 lapillus from C. spixii and 96 from G.

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.

Brazilian Archives of Biology and Technology, 2013 This study reports the first occurrence of partial albinism in two species of Ariidae: Genidens barbus and Genidens planifrons from an estuary of Southern Brazil. Possible causes of the simultaneous occurrence of three specimens with partial albinism are

Morphology of sagitta, lapillus and asteriscus of Patagonian Genidens barbus [PDF]
Marine and Fishery Sciences, 2022 Otoliths are calcium carbonate structures, deposited as aragonite, located in the inner ear of bony fish. In recent years, they have become a useful tool for the determination of fish species, trophic content, age studies, and the identification of fish

Marine and Coastal Fisheries, Volume 14, Issue 4, August 2022., 2022 Abstract Biological parameters relating to the reproductive biology of Conguito Sea Catfish Cathorops liropus were investigated in 1979–1984 and 2015–2018 from an estuarine system on the northwestern Pacific coast of Mexico. In the first period, the spawning season occurred during the dry–warm season (April–June), according with the percentage of ...
