Genetic structure of Pintado (Pseudoplatystoma Corruscans) in the influence area of Itaipu Binacional Dam

, 2018
Foram analisados 112 espécimes de Pseudoplatystoma corruscans, com marcadores microssatélites, das bacias do Alto e Baixo Paraná, para checar o impacto da fragmentação de habitat causado por usinas hidrelétricas com canais de piracema. Altos níveis de diversidade genética foram encontrados, sendo as amostras estruturadas em dois grupamentos ...

Genetic Divergence Between Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum (Siluriformes: Pimelodidae) in the Paraná River Basin [PDF]

Brazilian Journal of Biology, 2009
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 ...

Detection of megalocytivirus in Oreochromis niloticus and Pseudoplatystoma corruscans in Brazil

Diseases of Aquatic Organisms, 2022
The infectious spleen and kidney necrosis virus (ISKNV) belongs to the genus Megalocytivirus (MCV), a group of double-stranded DNA genome viruses. The aim of this study was to retrospectively analyze samples from suspected foci of MCV infection in freshwater fish in Brazil. Samples were collected from infected fish between 2017 and 2021.

Effects of trichlorfon organophosphate on the morphology of the gills and liver of Pseudoplatystoma corruscans

Journal of Environmental Science and Health, Part B, 2021
Possible changes in the morphology of the gills and liver of P. corruscans after exposure to TCF were evaluated. The fish were distributed into five groups in triplicate (n = 10 in each group: 0.0; 0.125; 0.25; 0.5; 1.0 mg/L of the commercial product NEGUVON®, for 96 h.

Genetic Variability of Pure Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum Individuals in the Paraná and Paraguay River Basins [PDF]

Fisheries Science, 2016
The presence of interspecific hybrid surubim (Pseudoplatystoma corruscans × Pseudoplatystoma reticulatum) in natural environments can put at risk the existence of the pure parental lineages. The aim of this study was to characterize the genetic variability of pure Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum individuals from rivers in ...

Pharmacokinetic of levamisole in speckled surubimPseudoplatystoma corruscans

Journal of Veterinary Pharmacology and Therapeutics, 2012
Intensification of production systems exposes fish to stress agents, such as poor water quality and crowding, affecting physiological condition of cultured fish, negatively influencing their immune system and increasing susceptibility to microorganism infections (Gopalakannan & Arul, 2006; Sado et al., 2010).
