The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Estimates of Spawning Stream Contributions to an Imperilled Bull Trout Metapopulation Utilizing Otolith Geochemistry and Redd Counts

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Migratory fish species have experienced substantial declines throughout aquatic habitats, but actions to manage and conserve migratory species require a better understanding of the relative contributions of local populations to the metapopulation.

Multidisciplinary Evaluation of a 10‐Year Restoration Program for Two Endangered Atlantic Salmon (Salmo salar) Populations

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Supportive breeding programs are widely implemented to counteract demographic collapse in threatened populations. Their long‐term success, however, depends on maintaining genetic diversity while ensuring that released individuals contribute effectively to wild populations.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

Fish and Fisheries, Volume 27, Issue 4, Page 813-830, July 2026.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform
