Length–Weight Relationships of Four Fish Species Belonging to the Genus Traccatichthys (Teleostei: Nemacheilidae) in Southern China

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
Traccatichthys is a genus of small benthic omnivorous nemacheiline loaches, with limited ecological and biological data available. Here, we described length–weight relationships (LWRs) for four Traccatichthys species from southern China. Fishes were sampled using stationary fish cages (10 m in length, mesh size: 0.5 cm) between January and April 2025 ...

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 ...

Climate‐Driven Habitat Loss and Natural Fragmentation Increase Extinction Risk and Compromise Population Viability in Freshwater Fish

Global Change Biology, Volume 31, Issue 12, December 2025.
The article aims at evaluating the effect of climate change on extinction risk in freshwater fish species. ABSTRACT Climate change is one of the major drivers of the current extinction crisis. In this context, determining the probability of species extinction is crucial.

Socio‐ecological complexity in managing long‐standing invasive water hyacinth in wetland agriculture and fisheries

People and Nature, Volume 7, Issue 10, Page 2407-2420, October 2025.
Abstract Managing long‐established invasive species in an ecosystem can be complex due to their multifaceted socio‐economic roles and use to the stakeholders, an issue requiring more attention. We measured the effects of water hyacinth (Pontederia crassipes), one of the world's most notorious invasive aquatic plants, on wetland agriculture, water ...

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou

Ecology and Evolution, Volume 15, Issue 9, September 2025.
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.

Spatial Organization of Fish Assemblages and Its Relation to Environmental Factors in the Lower Yalong River, China

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Obvious variations were found in fish assemblages depending on the stream order. There were three site groups, one covering the tributaries of the Anning River, one covering the Anning River, and one covering the lower Yalong River. From low‐ to high‐order rivers, the alterations of key species within the fish communities exhibited a turnover pattern ...
