Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

Journal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

Freshwater hydrology emerges as the strongest predictor of phenological variability in a Southeast Alaska steelhead trout (Oncorhynchus mykiss) population

Journal of Fish Biology, EarlyView.
Abstract Phenological variation, such as the migration trends of salmonids, may provide resilience in changing environmental scenarios, influencing individual survival and population productivity. Phenological shifts may be particularly consequential for anadromous species that rely on seasonal cues for migration between freshwater and marine habitats ...

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

Cytotoxicity Profiling of Tenacibaculum Extracellular Products on Chinook Salmon (Oncorhynchus tshawytscha) Gill Cell Line, OTgill1PFR

Journal of Fish Diseases, EarlyView.
ABSTRACT Tenacibaculosis is an important disease of marine fishes caused by bacteria of the genus Tenacibaculum. Pathogenic Tenacibaculum species or serotypes, including Tenacibaculum maritimum, T. dicentrarchi, T. finnmarkense and T. soleae, have been isolated from farmed Chinook salmon (Oncorhynchus tshawytscha) during disease outbreaks in Aotearoa ...

Development of a Multiplex Polymerase Chain Reaction Assay for Differentiating Three Lactococcus Species Associated With Piscine Lactococcosis

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscine lactococcosis is an important bacterial disease of farmed fish. The causative agents, Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis, are closely related, which complicates species‐level identification. We developed a conventional multiplex PCR assay targeting species‐specific genes identified by comparative ...

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

A bitter taste of fish: the temporality of salmon, settler colonialism, and the work of well-being in a Yupiaq fishing village

Ecology and Society, 2020
In southwest Alaska, dominant narratives of subsistence and conservation are concerned predominantly with material relations with fish, with the number of fish that are killed. In Akiak, an Alaska Native (Yupiaq) village located along the Kuskokwim River,

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

Restoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...
