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.

Isolation and characterization of microsatellite loci in Pseudoplatystoma corruscans (Siluriformes: Pimelodidae) and cross-species amplification

Molecular Ecology Notes, 2005
A total of five polymorphic microsatellites loci from Pseudoplatystoma corruscans were isolated and characterized. A population survey involving 43 specimens resolved a large number of alleles (range seven to eight among loci) and high observed ...

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).

Ciencia y Tecnologia Alimentaria, 2001
Abstract Resumen Resumo Fish is among all classes of meat, the most susceptible to autolysis, oxidation, hydrolysis of fat and microbial alteration. The surubi manchado (Pseudoplatystoma corruscans) is the most marketed fresh water fish in the North East of Argentina. The analyzed fishes came from the Parana river, 27° 17′ 30″ south latitude and 58° 59′

Growth curve comparison of native fish cachara (Pseudoplatystoma reticulatum) and cachapinta hybrid (P. reticulatum × Pseudoplatystoma corruscans)

Aquaculture, 2019
Abstract This study was undertaken to compare the growth curves of native fish cachara (Pseudoplatystoma reticulatum) and of the cachapinta hybrid (P. reticulatum × Pseudoplatystoma corruscans), both reared in net cages. The experiment was carried out for 216 days in net cages that were placed in a 24-ha dam, in a completely randomized experimental ...

Digestive enzymes and metabolic profile of Pseudoplatystoma corruscans (Teleostei: Siluriformes) in response to diet composition

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2004
Digestive enzyme responsiveness to feeding and associated adjustments of metabolism can be used to derive nutritionally effective diet formulations. Juvenile pintado (Pseudoplatystoma corruscans) were fed different diets. After feeding, fish were killed and blood, liver and white muscle were collected to evaluate metabolites.

Molecular identification of the hybrid between the catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum using a set of eight microsatellite markers

Journal of Fish Biology, 2013
This study distinguished hybrids of surubim or pintado Pseudoplatystoma corruscans and cachara Pseudoplatystoma reticulatum from pure strains using a set of eight microsatellite markers and population assignment methods. Applications of this molecular tool range from certification of hybrid‐free breeders in restocking conservation programmes to the ...

Generation, characterisation and applicability of a monoclonal antibody to hybrid surubim catfish Pseudoplatystoma corruscans (Agassiz) � Pseudoplatystoma fasciatum (Linnaeus) immunoglobulin

Comparative Clinical Pathology, 2004
Monoclonal antibodies (mAb) against hybrid surubim immunoglobulin (IgM) were produced. Screening, with an indirect enzyme-linked immunosorbent assay (ELISA), revealed three probes: PSIg 10, PSIg 13 and PSIg 28 specifically reacting to surubim IgM. No species cross-reactivity was found.

First record of the mating behaviour of the spotted surubim Pseudoplatystoma corruscans in the Uruguay River

Journal of Fish Biology, 2020
AbstractThe spotted surubim Pseudoplatystoma corruscans is a large migratory catfish native to the La Plata and San Francisco basins. Nonetheless, its reproductive dynamics and behaviour remain poorly understood. This brief note provides the first record of the mating behaviour of P. corruscans in natural conditions.
