A Mark‐Recapture Estimate of the Number of American Eels Arriving at the Lowermost Barrier on the Wolastoq|Saint John River, Canada

River Research and Applications, Volume 42, Issue 1, Page 40-59, January 2026.
ABSTRACT The upstream migration of juvenile American eels (Anguilla rostrata) is frequently obstructed by dams and other in‐stream barriers, leading to habitat loss and fragmentation, factors that are believed to contribute to the species' population decline.

Sequencing improves our ability to study threatened migratory species: Genetic population assignment in California's Central Valley Chinook salmon

Ecology and Evolution, 2016
Effective conservation and management of migratory species requires accurate identification of unique populations, even as they mix along their migratory corridors. While telemetry has historically been used to study migratory animal movement and habitat

Proteomic Analysis of Chinook Salmon (Oncorhynchus tshawytscha) Ovarian Fluid

PLoS ONE, 2014
The ovarian, or coelomic, fluid that is released with the egg mass of many fishes is increasingly found to play an important role in several biological processes crucial for reproductive success. These include maintenance of oocyte fertility and developmental competence, prolonging of sperm motility, and enhancing sperm swimming speed. Here we examined

Stream Restoration for the Spawning of Trout: How to Enhance the Egg to Fry Survival and to Monitor the Spawning Efficiency?

River Research and Applications, Volume 42, Issue 1, Page 123-148, January 2026.
ABSTRACT Today, salmonid management is largely based on river restoration. One of the fundamental elements is the creation of functional spawning sites. Key values of sedimentological characteristics must be defined in terms of granulometry, permeability, and oxygen concentration to ensure the best possible success of the operations.

The Socio‐Cultural and Spiritual Dimensions on Non‐Marketed Environmental Valuation

Sustainable Development, Volume 34, Issue S1, Page 407-426, January 2026.
ABSTRACT The present review aims to strengthen both the theoretical foundation and real‐world relevance of environmental valuation methods, especially in regions marked by cultural diversity or spiritual significance. Its goal is to explore how embracing socio‐cultural pluralism can support more inclusive, meaningful, and accepted environmental ...

Effects of cover and mesohabitat type on the abundance of young-of-the-year Chinook salmon

California Fish and Wildlife Journal
Snorkel surveys were conducted on the Sacramento River to investigate the relative importance of microhabitat and mesohabitat scales on the abundance of young of the year (YOY) Chinook salmon (Oncorhynchus tshawytscha), while taking into account temporal

Initial responses of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) to removal of two dams on the Elwha River, Washington State, U.S.A.

Frontiers in Ecology and Evolution
Large dam removal is being used to restore river systems, but questions remain regarding their outcomes. We examine how the removal of two large dams in the Elwha River, coupled with hatchery production and fishing closures, affected population ...

Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish Species

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors.
