Dynamic Spatial Forecasting of Sea Lice Abundances
Sea lice, Lepeophtheirus salmonis, are a major challenge to both aquaculture and wild salmon populations. L. salmonis infect salmonids, feeding on mucous, skin and flesh of infected fish, reducing fitness and increasing morbidity. The management of sea lice is a key consideration for farm operators …

Sea lice infestation on wild salmonids in the southern part of the Icelandic Westfjords
Laxalús, Lepeophtheirus salmonis og grálús Caligus elongatus, eru náttúruleg sníkjudýr á laxfiskum í sjó. Lýsnar nærast á slímhúð, roði og blóði fiskanna og valda þannig streitu hjá þeim. Þær geta einar og sér valdið dauða fiska séu þær í miklum mæli en geta auk þess borið með sér aðra sýkla. …

Molecular docking and geographical information systems as tools to assess the potential impact of veterinary medicines on non-target organisms and the environment
… concentrations (MECs) and potential impact of sea lice treatments on salmon farms in Scotland. Alternative methods for ecotoxicology testing including mixture toxicity, and the use of in silico techniques to predict the chronic impact of VMs on different species of aquatic organisms were also …

The effects of water quality on the growth of lumpfish (Cyclopterus lumpus)
… lumpus) are of economic value as a biological lice control of Atlantic salmon (Salmo salar) in sea cages, reducing or eliminating the need for chemical or mechanical treatments for sea lice (Lepeophtheirus salmonis, Caligus elongatus). Lumpfish aquaculture production is still in early stages …
