Evaluation of laserpuncture on testicular maturation and semen quality of the catfish Sorubim cuspicaudus

open access: yesAquaculture Reports
Sorubim cuspicaudus is a native catfish species with potential for aquaculture diversification in Colombia. However, captive reproduction is constrained by asynchronous gonadal maturation and low male semen volume.

Reproduction of duckbill catfish Sorubim lima in captivity (Siluriformes, Pimelodidae) by means of hormonal induction/
Reprodução em cativeiro do jurupecê Sorubim lima (Siluriformes, Pimelodidae) por meio de indução hormonal

open access: yesSemina: Ciências Agrárias, 2011
Sorubim lima is a migratory catfish that do not reproduce in lenthic environments such as those formed after construction of hydroelectric power plants. An alternative for conservation of the species in these environments is the stocking with fingerlings

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

open access: yesMol 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 ...

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

open access: yesJ 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 ...

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

open access: yesCladistics
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.

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]

open access: yesJ 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 ...

Individual identification of bony fishes using unique body markings: Implications and applications. [PDF]

open access: yesJ Fish Biol
Abstract The natural variation in animal body markings, such as spots, stripes and blotches, offers a powerful tool for researchers, conservationists, citizen scientists and resource managers to distinguish specific individuals within species. By building libraries of photo‐identified individuals, we can track and differentiate individuals over time ...

Use of Cryopreserved Sperm of Grass Carp (Ctenopharyngodon idella) for Seed Production at the Hatchery Level of Bangladesh-A Need for Development of Germplasm Repositories. [PDF]

open access: yesAquac Res
Grass carp (Ctenopharyngodon idella), a freshwater nonnative fish species, is a potential aquaculture candidate in Bangladesh. The seed of the species is produced in the hatcheries by hypophysation, but the quality of seedstock of grass carp is deteriorated due to inbreeding, negative selection, and interspecific introgression among fishes. To increase
