Simulated effects of increasing salmonid production on sea lice populations in Norway

Epidemics, 2021
Norway produces more than one million tonnes of salmonids every year, almost exclusively in open-water net pens. In 2014, the Norwegian government announced plans to increase salmonid production.

Allee Effects May Slow the Spread of Parasites in a Coastal Marine Ecosystem [PDF]

, 2011
Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects acting on parasites have rarely been considered in the analogous process of infectious disease establishment and ...

Microsomal triglyceride transfer protein in the ectoparasitic crustacean salmon louse (Lepeophtheirus salmonis)

Journal of Lipid Research, 2017
The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish.

Quantifying environmental impacts of cleaner fish used as sea lice treatments in salmon aquaculture with life cycle assessment

Journal of Industrial Ecology, 2021
Increasing pressure of sea lice, development of multi‐resistance to chemotherapeutants, and alternative delousing strategies have been raising concerns about the environmental impacts of salmon farming. Ectoparasitic sea lice and its treatments represent

ENSO and QBO modulation of the relationship between Arctic sea ice loss and Eurasian winter climate

Environmental Research Letters, 2022
The causality between Arctic sea ice decline and cold boreal winters has been widely debated recently and remains controversial. A major source of uncertainty in the sea ice-cold winter relationship originates from that the stratosphere polar vortex (SPV)

Semigroup analysis of structured parasite populations [PDF]

, 2009
Motivated by structured parasite populations in aquaculture we consider a class of size-structured population models, where individuals may be recruited into the population with distributed states at birth.

Salmon louse labial gland enzymes: implications for host settlement and immune modulation

Frontiers in Genetics
Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin.

Sea lice in Iceland: assessing the status and current implications for aquaculture and wild salmonids

Aquaculture Environment Interactions, 2019
This is the first in-depth study which quantifies lice infestation levels on wild and farmed salmonids in a fjord system in Iceland (Arnarfjörður, Westfjords) and gives a baseline for the assessment of sea lice infestation within Icelandic fjords.
