The impact of isosmotic conditions on the metabolism and hypoxia tolerance of a reportedly oxyconforming teleost. [PDF]

J Fish Biol
Abstract Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Molecular Characterization of Eustrongylides sp. Infecting Channa punctata in Bangladesh. [PDF]

Vet Med Sci
In this study, a total of 137 medium‐sized Channa punctata (17.5 ± 2.5 cm) were collected from different locations of Jamalpur and Netrokona district, Bangladesh and microscopically identified as belonging to the genus Eustrongylides based on morphological characteristics.

Water temperature and river discharge drive age‐dependent changes in brown trout (Salmo trutta) growth

Journal of Fish Biology, EarlyView.
Abstract Rivers and streams exhibit inherent variability in environmental conditions, particularly in water temperature and stream discharge. These factors can impact fish growth through both direct (i.e., physiological) and indirect (i.e., ecosystem productivity) mechanisms.

Unravelling β‐Diversity and the Role of Small Streams in Shaping Fish Communities Using a National‐Scale eDNA Database

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
The role of river size on fish communities remains underexplored in freshwater ecology. Small streams, despite accounting for 75% of stream length, are more vulnerable to human impacts and often lack legislative protection. Nevertheless, they can serve as refuges and rearing areas for fish, including rare or threatened species.

Landscape and Hydro‐Climatic Drivers of Fish Communities in Floodplain Wetlands

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Floodplain wetlands are characterised by dynamic hydrological regimes and seasonal patterns of wetting and drying. They support distinct communities of fish, many of which are adapted to dynamic and variable conditions. Seasonal hydrological variation and the degree of water permanence influence physicochemical conditions and local habitat ...

Catch Me If You Can: Assessing Sampling Techniques for Threatened Floodplain Wetland Fish

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Floodplain wetlands are declining globally in extent and ecological condition. Changing climates, increasing agricultural activity and invasive species are among the key threats contributing to biodiversity loss, with native fish species increasingly in decline and listed as threatened or endangered. Floodplain wetlands present unique sampling

Environmental DNA as a Detection and Quantitative Tool for Brown Bullhead Catfish (Ameiurus nebulosus): A Comparison With Conventional Netting

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.

Impacts of climate change on temperature and dissolved oxygen in an oligotrophic deep lake

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Climate change has significant effects on freshwater ecosystems, including lakes, influencing key water quality indicators such as water temperature and dissolved oxygen concentrations (DO). This study uses a 3D hydrodynamic model (AEM3D) coupled with a simple biogeochemical module (iWQ) alongside observations to examine historical changes in ...
