The integrated reproductive response: the scope for seasonal phenotypic flexibility shapes reproductive outcomes across fish populations

open access: yesOikos, EarlyView.
Across north‐temperate environments, rapid environmental change has disrupted the seasonal life histories of resident organisms, decreasing the reliability of environmental cues. Flexible responses capable of buffering the effects of unpredictable environmental variation to defend performance and reproductive outcomes may thus be key to species‐ and ...

Results for trawl surveys of juvenile pink salmon in the Bering and Okhotsk Seas in 2025 and prospects for the species return and catch in the Karaginskaya subzone and Okhotsk Sea in 2026

open access: yesИзвестия ТИНРО
Surveys of juvenile pink salmon during their feeding in the sea in fall season provide information on possible returns of pink salmon in the next year used for the catch forecasting.

Recovery of the stocks of the European eel (Anguilla anguilla) by spawner enhancement

open access: yesInformationen aus der Fischereiforschung - Information on fishery research, 2006
The production of healthy high quality female European eel in recycle systems is proposed as a means to secure sufficient numbers of silver eel for spawning migration in order to meet the requirements of the European Commission’s proposal for a Regulation for the recovery of the stock of the European eel.

The Return of the Allis Shad (Alosa alosa) to the Lower Navigable Reaches of the Seine: Locks Play a Role

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT In France, it is estimated that shads (Alosa spp.) have lost 69% of their historical range, mainly due to disrupted river connectivity. After an absence of one century, signs of their return in the Seine River have been recorded over the past two decades: adult and juvenile specimens have been caught by anglers or recorded at video‐counting ...

A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Reproductive Strategies of the European Catfish at Its Southern Invasion Front: Insights from the Tagus River

open access: yesProceedings
Introduction: The European catfish (Silurus glanis) has expanded rapidly across Europe, significantly impacting native freshwater biodiversity. Despite its well-documented ecological and economic effects as a top predator, reproductive biology data from ...

Fish Migration Through Ship Locks at the Danube River, Austria

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Longitudinal connectivity in the Austrian section of the Danube has improved over the last three decades thanks to the progressive installation of fish passage facilities at hydropower plants. However, navigation locks which are present at all barrages remain poorly quantified with respect to their role in fish migration.

Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.
