Impact of light pollution on fishes: Mechanisms and ecological consequences

Journal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

Cloned and outbred Atlantic salmon display equal parasite dispersion when infected with the salmon louse

Aquaculture, 2017
Abstract The salmon louse is an ectoparasitic copepod that infects salmonids in the marine environment. This parasite causes a major economic and biological challenge to the Atlantic salmon farming industry, and efforts to increase the resistance of salmon to this parasite are ongoing.

Energetic costs of catch and release angling in Brook Trout (Salvelinus fontinalis) at two temperatures

Journal of Fish Biology, EarlyView.
Abstract Catch and release (C&R) angling is a common practice in recreational fisheries, which can involve a range of acute stressors for fish that lead to physiological and behavioural impairments. Following a C&R event, energy is expended to fuel recovery, while a cessation in feeding can limit energy intake.

Expert‐Based Prioritization of Control Measures for Salmonid Rickettsial Septicemia in Chilean Salmon Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsiosis (SRS) remains the main infectious disease affecting salmon aquaculture in Chile. This study evaluated expert perceptions of the effectiveness of SRS control measures and the level of agreement among industry professionals.

Assessment of Salinity Tolerance in Lepeophtheirus salmonis Following Five Generations of Freshwater Treatment Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...

Divergent Healing Trajectories Among Common Mechanical Skin Wound Types in Post‐Smolt Atlantic Salmon (Salmo salar Linnaeus, 1758)

Journal of Fish Diseases, EarlyView.
ABSTRACT Mechanical wounds are a common form of skin damage in Atlantic salmon (Salmo salar Linnaeus, 1758) aquaculture and can predispose fish to secondary infections. Such wounds often arise from routine farming practices, including delousing operations.

RNA-Seq analysis using de novo transcriptome assembly as a reference for the salmon louse Caligus rogercresseyi.

PLoS ONE, 2014
Despite the economic and environmental impacts that sea lice infestations have on salmon farming worldwide, genomic data generated by high-throughput transcriptome sequencing for different developmental stages, sexes, and strains of sea lice is still ...

‘Let's Go to the Land Instead’: Indigenous Perspectives on Biodiversity and the Possibilities of Regenerative Capital

Journal of Management Studies, EarlyView.
Abstract The land has been a source of capital accumulation since colonization through extractive activities like mining and industrial agriculture. Indigenous peoples have profoundly different relationships with the land, which are more relational than extractive. However, their knowledge has been subjugated by and systematically excluded from Western

Chitin synthesis in the salmon louse Lepeophtheirus salmonis

, 2021
The salmon louse Lepeophtheirus salmonis is a parasitic copepod that lives and feeds on Atlantic salmon (Salmo salmar). At present, this parasite is the number one threat to the Norwegian aquaculture. The density of salmons living together in aquaculture sea cages gives the salmon lice optimal conditions for infecting and reproducing.
