Evaluation of protein isolate obtained from byproducts of hybrid sorubim (Pseudoplatystoma reticulatum x Pseudoplatystoma corruscans)

Journal of Bioenergy and Food Science, 2018
Industrial fish processing generates large quantities of protein-rich byproducts, which are usually discarded because of their low commercial value.

Evaluation of Ethylene Glycol as a Cryoprotectant in the Sperm Cryopreservation of Trans-andean Shovelnose Catfish (Sorubim Cuspicaudus, Pimelodidae)

Acta Biológica Colombiana, 2014
The catfish Sorubim cuspicaudus cryopreservation semen was evaluated using three levels (5, 10, 15%) of ethylene glycol (ETG). Males (n = 13) undergoing spermiation and in final maturation females (n = 6) were induced with 0.4 ml Ovaprim®/Kg, after 12 ...

Valorization of pulp and viscera from hybrid sorubim and pacu by production of protein concentrate using alkaline solubilization

Aquaculture and Fisheries
Fish protein concentration (FPC) by alkaline solubilization has proven to be an alternative method in adding value to muscle-based materials. The aim of this work was to evaluate the influence of different processes (decanting/sieving or centrifugation),

First Report of Vibrio vulnificus Outbreak in Farm-Raised Sorubim (Pseudoplatystoma sp.) from Brazil

Fishes
Vibrio vulnificus is an opportunistic pathogen in humans and exhibits pathogenic behavior in several aquaculture fish species. To date, in Brazil, there are no reports of V. vulnificus outbreaks in farmed fish. However, in 2019, sorubim (Pseudoplatystoma

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]

Mol Ecol
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Establishing new grid-size-dependent attributes to rank areas of endemism for conservation priorities. [PDF]

Cladistics
Abstract Delineating Areas of Endemism (AEs) is crucial for identifying priority areas for biodiversity conservation in a spatial planning framework. Endemicity Analysis in the NDM/VNDM software is one of the primary methodologies for its delineation.

Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin. [PDF]

J Fish Biol
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods. [PDF]

J Fish Biol
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

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]

J Fish Biol
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 ...
