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.

A review of the biology and genetics of sea lice [PDF]

ICES Journal of Marine Science, 2006
Abstract Studies of the biology of sea lice have been conducted from various perspectives for two decades. For Lepeophtheirus spp., most of the published literature has centred on the economically important Lepeophtheirus salmonis, while for Caligus spp., research has focused on a wider range of species.

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.

Using sentinel cages to estimate infestation pressure on salmonids from sea lice in Loch Shieldaig, Scotland

Aquaculture Environment Interactions, 2014
Sentinel Atlantic salmon, held in cages, were used to estimate the monthly infestation pressure of sea lice at 3 locations along a salmonid migration route in Loch Shieldaig, a Scottish west coast sea loch.

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.

Sea lice gap analysis [PDF]

Sea lice are a major health hazard for farmed Atlantic salmon in Europe, and their impact is felt globally. Given the breadth of ongoing research in sea lice dispersal and population modelling, and focus on research lead adaptive management, we brought

Evaluating the effect of synchronized sea lice treatments in Chile

Preventive Veterinary Medicine, 2017
The sea louse is considered an important ectoparasite that affects farmed salmonids around the world. Sea lice control relies heavily on pharmacological treatments in several salmon-producing countries, including Chile. Among options for drug administration, immersion treatments represent the majority of antiparasitic control strategies used in Chile ...

Are CSR incidents truly bad news?

Journal of Financial Research, EarlyView.
Abstract We revisit whether disclosures of negative Corporate Social Responsibility (CSR) incidents adversely affect firms' stock prices. While univariate tests reveal significant negative abnormal returns around incident announcements, the effect disappears once firm characteristics, industry, and time‐fixed effects are controlled for.
