A flume study to evaluate the processes governing retention of sea lice therapeutants using skirts in the treatment of sea lice infestation

Aquaculture, 2011
Results are presented from laboratory model investigations into the processes governing the retention of therapeutant added to skirted fish cages during treatment for sea lice infection. The results demonstrate the importance of turbulent entrainment and shear at the edges of the skirt in reducing the concentration of therapeutant within the cage.

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.

Salmon louse Lepeophtheirus salmonis predominates over Caligus elongatus on Atlantic salmon post-smolts in central and western Norway

Aquaculture Environment Interactions
Atlantic salmon Salmo salar are exposed to parasitic sea lice as they enter the marine environment, particularly in areas with high densities of open net-pen salmon farming, where infestations can reach harmful levels.

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.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype associated with pyrethroid resistance

Aquaculture Environment Interactions, 2019
Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters.

Screening of blood and mucus parameters towards breeding for resistance to salmon louse (lepeophtheirus salmonis) in atlantic salmon

, 2012
Over the last three decades salmon farmers have experienced serious economic hardships due to losses caused by sea lice (Lepeophtheirus salmonis) infestations. In the absence of an effective vaccine, inefficiency of biological control methods and growing

Extracting vitalities: Cuts in Indigenous women's bodies‐territories (Brazil)

Medical Anthropology Quarterly, EarlyView.
Abstract In this article, I explore the connections between the medicalization of childbirth and environmental devastation through Guarani‐Mbyá understandings of life and the living. I argue that the cuts made to Guarani‐Mbyá women's vaginas (episiotomies) in Brazilian hospitals are experienced and situated on the same cosmopolitical level as the cuts ...

An Account of Luck, Fortune, and Fate

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT Luck is one of our most important concepts. In this article, I first argue that extant accounts of luck are deeply flawed. I then argue for a hybrid account of luck that is based around the difference between skill‐based and non‐skill‐based events.

Timing and probability ofarrival for sea lice dispersingbetween salmon farms

, 2022
Sea lice are a threat to the health of both wild and farmed salmon and an economic burden for salmon farms. With a free-living larval stage, sea lice can disperse tens of kilometres in the ocean between salmon farms, leading to connected sea louse ...
