Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

Journal of Fish Biology, Volume 109, Issue 1, Page 371-383, July 2026.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Habitat‐Driven Sexual Dimorphism in Triplophysa strauchii Between Oxbow Lake and Stream: A Geometric Morphometric Analysis

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The combined effects of sexual selection and natural selection give rise to sexual dimorphism in operculum and eye morphology of T. strauchii across the two river basins. And our study reveal the fine‐scale responses of fish sexual dimorphism to diverse selective forces.

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

Journal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Pharmacokinetics, Optimal Dosages, and Withdrawal Time of Florfenicol in Cobia (Rachycentron canadum) After Oral Administration via Medicated Feed

Journal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 3, Page 343-351, May 2026.
ABSTRACT Antimicrobial drugs are commonly used for the treatment of bacterial diseases in cobia (Rachycentron canadum), but information regarding the rationale of their therapeutic use, such as pharmacokinetics (PK), optimal dosages, and withdrawal time (WDT) in this species is very rare.

Findings From the Pearl River Basin: Dissolved Oxygen Dominates Functional Trait Filtering and Diversity Patterns in Urban Rivers

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Urbanization 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 ...

Genomic Insights Into Carnivorous Fish in the Characiformes

Ecology 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 ...

Utilizing Environmental DNA Metabarcoding to Assess Fish‐Based Food Resources in Key Foraging Areas of the Black Stork

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study employed environmental DNA (eDNA) to assess fish‐based food resources in key foraging areas of the Black Stork (Ciconia nigra)—Zhanghe Canyon and Qixi River National Wetland Parks in Henan, China. Results show that the main prey in these habitats are fish from the orders Siluriformes, Cypriniformes, and Perciformes, with no significant ...
