Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Low eDNA sampling effort (< 10 sample sites) using a portable on‐site kit with syringe filters and a modest water volume (< 500 mL per site) provided a rapid and robust snapshot of fish biodiversity. Environmental DNA based species richness increases along the upstream‐downstream gradient showing a significant negative correlation with river elevation ...

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.

Desempeno del sabalo Prochilodus lineatus en policultivo con pacu Piaractus mesopotamicus

Latin American Journal of Aquatic Research, 2016
In fish farming 30% of the nutrients provided are retained as animal biomass, and the remainder is lost in the sediments. An alternative is to produce in polyculture, to take advantage of space and food. The aim of this work was to compare and evaluate the growth of Prochilodus lineatus (PL) in monoculture, in contrast to polyculture of PL and pacu ...

Impacts of Global Warming on Quality of Male Fishes: Evidence From A Meta‐Analysis of Temperature Effects on Sperm Motility Kinematics

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...
