Beyond Occurrence: Evidence Gaps for Non‐Native Freshwater Fishes in Brazilian Drylands

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Non‐native freshwater fishes are widely reported in inland waters, but occurrence records are often interpreted together with stronger evidence of establishment, reproduction, spread, pathways and impacts. This can overstate what published records support, especially in regions where reservoirs, river‐basin transfers and artificial ...

Estimation of genetic parameters for weight and length gains in tambaqui (Colossoma macropomum)

open access: yesBrazilian Journal of Biology, 2023
Abstract The goal of this study was to determine the genetic parameters for growth traits in tambaqui (Colossoma macropomum) fish of similar age and weight. The data set included monthly measurements of body weight and length from120 fish for a year (1,440 measurements). The study found that weight gain had a heritability estimate of 0.01, while length

Dimorfismo sexual no desempenho do tambaqui Colossoma macropomum (Teleostei: Serrasalmidae). [PDF]

open access: yes, 2022
O Tambaqui (Colossoma macropomum) é o principal peixe de água doce na aquicultura nativa do Brasil. Apesar disso, informações sobre crescimento e maturidade sexual ao longo do cultivo ainda hoje são escassas. O objetivo do presente trabalho foi avaliar a

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Genomic Insights Into Carnivorous Fish in the Characiformes

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study employed comparative genomic approaches using 12 high‐quality Characiformes genomes (covering nine subfamilies) with zebrafish as an outgroup to explore the molecular mechanisms underlying the carnivorous adaptation of Characiformes. Expanded gene families, positively selected genes, and rapidly evolving genes in carnivorous species were ...
