Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil

Journal of Fish Biology, EarlyView.
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Does turbulence affect the habitat choice of Atlantic salmon parr? [PDF]

, 2007
Habitat preferences of Atlantic salmon parr are commonly described using mean flow velocity, water depth, and substrate as habitat variables, and a variety of habitat models have been developed using these variables to predict habitat quality.

Inshore marine coastal zone migration patterns in Atlantic salmon post‐smolts emigrating from eight rivers in north‐east Scotland

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon, Salmo salar, migrate through multiple habitat types, each having the potential to impact differently upon migration success. The inshore marine coastal zone is arguably disproportionately impacted by potential stressors on populations.

Temporal allele frequency changes in large‐effect loci reveal potential fishing impacts on salmon life‐history diversity

Evolutionary Applications
Fishing has the potential to influence the life‐history traits of exploited populations. However, our understanding of how fisheries can induce evolutionary genetic changes remains incomplete.

Reproductive parameters of wild and hatchery‐reared sea trout (Salmo trutta m. trutta L.) females from the Łeba River (southern Baltic Sea)

Journal of Fish Biology, EarlyView.
Abstract Sea trout Salmo trutta m. trutta L. has high socioeconomic and ecological importance in the Atlantic region; therefore, stocking hatchery‐reared fish is widely practiced for stock enhancement and recovery of wild populations. In this study, fecundity of wild and stocked hatchery‐reared sea trout sampled from the Łeba River (southern Baltic Sea

“Consumers’ Preferences Toward Farmed Salmon in China: Integrating Sensory and Choice Experiments”

Food Frontiers
China's growing demand for farmed salmon is apparent, with the country importing 190 thousand tonnes valued at over $1.12 billion in 2023. In response, the Chinese government allowed rainbow trout to be labelled and sold as salmon starting in 2018 ...

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

Journal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Return migration to fresh water and overwintering locations used by sympatric anadromous populations of Arctic char (Salvelinus alpinus) and Dolly Varden (Salvelinus malma malma)

Journal of Fish Biology, EarlyView.
Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...

The use of tricaine methanesulfonate, clove oil, metomidate, and 2-phenoxyethanol for anesthesia induction in alewives (Alosa pseudoharengus) [PDF]

, 2015
Anesthetics are widely used in routine aquaculture operations to immobilize animals for tagging, spawning, handling, and vaccination. A number of anesthetics are currently available for finfish, but their efficacy and optimal dosage is highly species ...

The lake sink in Atlantic salmon smolt downstream migration

Journal of Fish Biology, EarlyView.
Abstract The objective was to estimate the movements and survival of Atlantic salmon smolts migrating downstream through a river–lake system consisting of two large, interconnected lakes (areas 58.2 and 13.2 km2, minimum crossing distance 29 and 16 km).
