Beyond barriers: fish assemblage recovery following dam removal on the Cuyahoga River, a Lake Erie tributary

open access: yesRestoration Ecology, EarlyView.
Dam removals are increasing globally, yet ecological outcomes vary widely because biological recovery depends on post‐removal connectivity and access to source populations. We evaluated how multiple dam removals and remaining fragmentation influenced fish assemblage recovery in the Cuyahoga River (OH, United States), a historically polluted Great Lakes

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

open access: yesEcology 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 ...

Integrated Metabolomics and Gut Microbiota Analysis Reveal the Intestinal Stress Response of Juvenile Four‐Finger Threadfin (Eleutheronema tetradactylum) to Nitrite Exposure

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
Nitrite exposure induces intestinal stress in juvenile Eleutheronema tetradactylum, characterized by microbial dysbiosis, metabolic reprogramming, and altered digestive enzyme activities. Integrated metabolomics and microbiota analyses reveal coordinated hostmicrobe responses involving key pathways such as ABC transporters and amino acid metabolism ...

Evaluation of Liver Damage and Herbal Detoxification of Coral Reef Fish Caused by Ammonia Stress

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
Slybum marianum can reduce ammonia stress and enhance liver protection in marine fish. ABSTRACT Ammonia nitrogen can cause serious toxicological damage to fish and cause fish death. This study focused on liver damage caused by ammonia nitrogen stress in coral reef fish and used herbal extracts to improve ammonia poisoning and prevent liver tissue ...
