Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Study on the prevalence and intensity of three parasites in Sturgeon fingerlings cultured in earthen ponds

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2007
In 2001, we studied 2600 sturgeon fingerlings including: 2242 Acipenser persicus, 150 Acipenser stellatus, 150 Acipenser nudiventris and 58 Huso huso from Shahid Beheshti and Yousefpour hatcheries for parasitic infection.

Whole‐Genome Sequencing and Resequencing of Hucho bleekeri Provides Insights into Genetic Mechanisms of Environmental Adaptation

Integrative Zoology, EarlyView.
A high‐quality chromosome‐level reference genome was constructed for Hucho bleekeri. Population structure and environmental adaptation of Hucho species were revealed by whole‐genome resequencing. ABSTRACT Salmonidae represents an important family in the study of genome evolution following genome duplication.

THE ABUNDANCE AND SPECIES COMPOSITION OF STURGEON IN THE NORTHERN CASPIAN SEA

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2008
This study was carried out in the northern Caspian Sea on Gidrobiolog vessel in summer 2006 to assess the abundance and species composition of sturgeons. We used bottom trawl (9m) and gillnets with mesh size 60, 110, 250 and 29Omm.

A new acoustic telemetry tag that identifies carrier mortality by monitoring activity level

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1735-1742, June 2026.
Abstract We present a new acoustic telemetry tag capable of detecting whether its carrier stops moving for long enough to presume the organism has died, and of reporting the time elapsed since movement ceased. The tag uses existing environmental sensor technology together with an algorithm with user‐specifiable thresholds, and importantly, can separate

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...
