Description of Encephalon Morphology of Nile Tilapia Oreochromis niloticus (Linnaeus, 1758) (Perciformes: Cichlidae) From Brazil

Anatomia, Histologia, Embryologia, Volume 55, Issue 1, January 2026.
ABSTRACT The Nile tilapia (Oreochromis niloticus) is a cichlid species native to Africa and is widely farmed in tropical and subtropical regions around the world, making it one of the most commercially important aquaculture species. Despite its significance, there is still a lack of detailed anatomical descriptions of its brain.

Macro‐Hybrid and Micro‐Hybrid of Fish

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT This study reviews the progress in fish breeding, focusing on distant hybridization and gynogenesis, and introduces the theory of macro‐hybrid and micro‐hybrid. The macro‐hybrid refers to the allo‐progeny derived from distant hybridization, including the allo‐progenies.

Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications

The Anatomical Record, Volume 308, Issue 12, Page 3069-3081, December 2025.
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

Assessing Current Fish Diversity in the Yellow River Basin by Integrating Large‐Scale Barcoding and Morphological Data

Ecology and Evolution, Volume 15, Issue 12, December 2025.
In this study, 127 sampling points were sampled in the Yellow River Basin, and a DNA barcode database of 3011 sequences and 110 species was constructed. We found that diversity of fish species in the Yellow River Basin has been seriously underestimated.

Brain Transcriptomics Reveals Molecular Mechanisms of Cave Adaptation in Triplophysa Loaches

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study compares brain transcriptomes of cave (Triplophysa shilinensis) and surface‐dwelling (T. xiangshuingensis) loaches to uncover molecular adaptations to subterranean life. We identified widespread gene down‐regulation in the cave ecotype, with enriched pathways in energy metabolism, circadian rhythms, sensory perception, and body coloration ...

Genomic Insights Into Diversity, Phylogeny, Hybridization and Evolutionary History of Palearctic Fish Genus Rutilus (Leuciscidae)

Diversity and Distributions, Volume 31, Issue 12, December 2025.
ABSTRACT Aim Using a widely distributed and frequently hybridising fish (genus Rutilus) in the Palearctic as a model system, we re‐evaluated a series of hypotheses on phylogeny, taxonomy, phylogeography and the role of hybridization in evolutionary history based on the first large‐scale analyses of nuclear SNPs together with mtDNA data obtained from ...

Description of a New Eyeless Cavefish Species Using Integrative Taxonomic Methods—Sinocyclocheilus changlensis (Cypriniformes, Cyprinidae), From Guangxi, China

Ecology and Evolution, Volume 15, Issue 11, November 2025.
The karst landscapes of southwestern China, one of the world's largest, support a high diversity of cavefish, including the Sinocyclocheilus genus, which has 84 species adapted to subterranean life. Here, we describe a new species, Sinocyclocheilus changlensis, distinguished by traits such as eyelessness, unpigmented scales, and unique morphological ...
