Radiotagging a long-distance migratory characid fish: reproduction after surgery, tag losses, and effects in weight

Neotropical Ichthyology, 2021
Although biotelemetry studies bring useful information, tagging is a highly invasive procedure. For this reason, we assess if intracoelomic tagging alters survivorship, weight gain and/or reproductive capacity of a neotropical migratory fish.

Fish hatchering and its effects on the morphology of Prochilodus lineatus (Actinopterygii: Prochilodontidae) [PDF]

Brazilian Journal of Biology, 2016
Abstract The fish stocking in captivity for later release into natural water bodies has historically been applied in Brazil, as a measure to mitigate impacts caused by dams. However, the released fish are adapted to the hatchery environment, which is totally different from the natural, which results in low post-release survival rates and ...

Invasive Fishes Interact With Temperature to Reshape Community Size Structure Across Climatic Zones

Global Change Biology, Volume 32, Issue 4, April 2026.
Non‐native fishes are reshaping lacustrine communities across climatic zones worldwide through trophic‐ and temperature‐dependent pathways that are leading to flatter size spectrum exponents and a decline in the total biomass of the native community.

Genetic diversity of migratory fish populations of the Rio Grande Reservoir (São Paulo, Brazil)

Semina: Ciências Agrárias, 2019
In recent years, anthropogenic factors such as pollution, overfishing, and construction of hydroelectric plants have significantly impacted natural fish populations. Research focusing on genetically evaluation of these impacts is necessary to objectively

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

Journal of Fish Biology, Volume 108, Issue 1, Page 43-56, January 2026.
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 ...

First Records of Length–Weight Relationships for Ten Fish Species From the Middle Stretch of the Uruguay River, Southern Brazil

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
This study estimated the length–weight relationships (LWRs) of 10 fish species from the middle stretch of the Middle Uruguay River basin, aiming to provide new morphometric data and contribute to the knowledge of Neotropical ichthyofauna. Fish were collected at seven sites with sampling conducted at each site during every season, totaling 84 sampling ...
