Findings From the Pearl River Basin: Dissolved Oxygen Dominates Functional Trait Filtering and Diversity Patterns in Urban Rivers. [PDF]
Ecol EvolUrbanization reshapes fish communities via environmental filtering. Surveying 44 sites across an urban (Huadi) and a relatively natural (Zengjiang) river in the Pearl River Basin (2024), we linked environmental variables to fish functional traits using RLQ and SEM, finding that dissolved oxygen is the dominant filter in urban reaches—selecting low ...

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

Toxicological Effects of Lufenuron on Antioxidant Defence in Grass Carp (Ctenopharyngodon idella). [PDF]
Vet Med SciGRAPHICAL ABSTRACT Lufenuron exposure in grass carp disrupted antioxidant enzyme activities in a tissue‐specific manner, indicating oxidative stress. Superoxide dismutase and glutathione increased, whereas catalase and peroxidase showed organ‐dependent alterations, highlighting antioxidant enzymes as sensitive biomarkers for assessing ecotoxicological ...

Effects of Low Concentration of Glyphosate-Based Herbicide on Genotoxic, Oxidative, Inflammatory, and Behavioral Meters in Danio rerio (Teleostei and Cyprinidae). [PDF]
Biochem Res IntThe glyphosate herbicide is a pesticide widely used in the world and can contaminate soil, air, and water. The objective of this work was to evaluate the toxicity of a glyphosate‐based herbicide (GBH) in zebrafish (Danio rerio). Fish were exposed to different concentrations of GBH (0, 50, 250, and 500 µg/L) for 96 hours.

Different stocks of Prochilodus lineatus along the Cinzas River basin: contributions from a free-flowing tributary in the Capivara Reservoir region, Paranapanema River basin (upper Paraná River) [PDF]
Neotropical Ichthyology, 2023 Dams are one of the main threats to Neotropical potamodromous fish, causing blockages of migratory routes and loss of breeding areas in an increasing number of drainage systems.

Estudio del desarrollo embrionario del sábalo (Prochilodus lineatus) [PDF]
Archivos de medicina veterinaria, 2010 El almacenamiento de espermatozoides de peces por medio de la criopreservacion es muy utilizado hoy en dia. Si bien se sabe que el proceso de congelamiento/descongelamiento genera la fragmentacion del ADN del espermatozoide, no se conocen las consecuencias que esto tiene en el desarrollo embrionario.

Digestive aspartic proteases from sábalo (Prochilodus lineatus): Characterization and application for collagen extraction [PDF]
, 2018 Acid proteases from sábalo stomach mucosa were recovered using salting-out procedure. This single step produced an enzyme extract purified 1.8-fold over the crude extract with a recovery of 45.1% of its initial proteolytic activity.

Scale morphology of Prochilodus lineatus with emphasis on the scale epithelium [PDF]
Brazilian Journal of Biology, 2013 The fish body is entirely covered by a thin, smooth and glandular epidermis, closely attached to the scales inserted on the dermis. The descriptive work on this tissue dates to twenty or thirty years ago, bears very little photographic record and does not focus on the scale epithelium, despite the fact that it is in direct contact with the environment.
