Morphological deformities in the osseous structure in spotted sorubim Pseudoplatystoma coruscans (Agassiz & Spix, 1829) with vitamin C deficiency.

Genetic divergence between Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum (Siluriformes: Pimelodidae) in the Paraná River Basin.

Pseudoplatystoma corruscans (Spix and Agassiz, 1829) and Pseudoplatystoma reticulatum (Eingenmann and Eigenmann, 1889) are large migratory catfishes of high biological importance and great commercial value in South America. Because fertile crossbreeds can be artificially produced in hatcheries, a high genetic proximity between these two Pimelodidae species is conceivable. Possible escape of cro...

First isolation and characterization of Lactococcus garvieae from Brazilian Nile tilapia, Oreochromis niloticus (L.), and pintado, Pseudoplathystoma corruscans (Spix & Agassiz).

Lactococcus garvieae infection in cultured Nile tilapia, Oreochromis niloticus (L.), and pintado, Pseudoplathystoma corruscans (Spix & Agassiz), from Brazil is reported. The commercial bacterial identification system, Biolog Microlog, confirmed the identity of L. garvieae. Infectivity trials conducted in Nile tilapia using Brazilian Nile tilapia L. garvieae isolates resulted in a median lethal ...

Microhabitat of Monogenea and Copepodids of Lernaea Cyprinacea on the Gills of Four Brazilian Freshwater Fish Micro Hábitat Branquial De Monogenea Y Copepoditos De Lernaea Cyprinacea En Las Branquias De Cuatro Peces Brasileños De Agua Dulce

This study evaluated the ectoparasite distribution on the gill archs of pond-reared pacu (Piaractus mesopotamicus Holmberg, 1887), hybrid patinga (P. mesopotamicus female x P. brachypomus (Cuvier, 1817) male), hybrid tambacu (Colossoma macropomum (Cuvier, 1816) female x P. mesopotamicus male) and hybrid surubim (Pseudoplatystoma reticulatum female x P. corruscans Spix & Agassiz, 1829 male). A t...

Metazoan parasites of Brazilian menhaden Brevoortia aurea (Spix & Agassiz, 1829) (Osteichthyes: Clupeidae) from the coastal zone of the State of Rio de Janeiro, Brazil.
