Development of gluten-free fish (Pseudoplatystoma corruscans) patties by response surface methodology [PDF]
Journal of Food Science and Technology, 2018 The goal of this study was to develop a fish-based product suitable for people with celiac disease. Water and gluten-free flours (rice, corn, amaranth or quinoa) were added to improve cooking yield, texture parameters and as an aid in improving quality attributes such as taste and juiciness.

Survival and growth of Pseudoplatystoma corruscans (Pisces - Pimelodidae) larvae: effect of photoperiod Sobrevivência e crescimento de larvas de surubim, Pseudoplatystoma corruscans (Pisces, Pimelodidae): efeito do fotoperíodo [PDF]
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2008 The survival and the growth of Pseudoplatystoma corruscans larvae exposed to four photoperiods: light:dark (LD) 0:24, LD 10:14, LD 14:10, and LD 24:0, in a brackish water (5‰) culture were analyzed. Larvae were fed with Artemia sp. nauplii at a 500

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 ...

Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of Hypancistrus (Siluriformes: Loricariidae) in the Xingu River [PDF]
Ecology and Evolution, Volume 16, Issue 5, May 2026.We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.

DNA metabarcoding assessment of Neotropical ichthyoplankton communities is marker‐dependent [PDF]
Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023 DNA metabarcoding has been applied as a rapid, cost‐effective, and accurate taxonomy tool, allowing the identification of multiple individuals simultaneously. The combined use of the three markers increased the genera detection rates by 25%–87.5%, allowing an increased taxonomic coverage and robust taxonomic identification of complex Neotropical ...

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures [PDF]
Journal of Fish Biology, Volume 108, Issue 1, Page 69-85, January 2026.Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...
