Background: Infestations of the parasitic copepod Lepeophtheirus salmonis, commonly referred to as sea lice, represent a major challenge to commercial salmon aquaculture. Dependence on a limited number of theraputants to control such infestations has led to concerns of reduced sensitivity in some se...

Analyses of a unique database containing sea lice records over an 11 year period provide evidence of changing infestation patterns in Scotland. The data, collected from more than 50 commercial Atlantic salmon farms, indicate that both species of sea lice commonly found in Scotland, Lepeophtheirus sa...

Most lice infestations on salmon farmed in the North Atlantic are attributed to Caligus elongatus and Lepeophtheirus salmonis. This study reports findings from time-series analysis conducted on observations of the lesser-studied C. elongatus, in four farms on the west coast of Scotland over the peri...

In everyday life there are low risk situations where resources normally need to be protected and thus access to them controlled, but at the same time the implications of occasional unauthorized access are not severe. In these situations using an authentication technique that is expensive or requires...

Conservation management of wild fish may include fish health management in sympatric populations of domesticated fish in aquaculture. We developed a mathematical model for the population dynamics of parasitic sea lice (Lepeophtheirus salmonis) on domesticated populations of Atlantic salmon (Salmo sa...

In order to investigate whether the efficacy of emamectin benzoate (SLICE) against sea lice (Lepeophtheirus salmonis) infestation in Atlantic salmon had changed in Scotland, UK, in the period since regular application of the drug began, sea lice abundance and treatment data were examined from 56 wes...

Although Caligus elongatus is one of two major species of sea lice that parasitize farmed salmon, its epidemiology has not been extensively studied. In this communication, the abundances of the adult stage of C. elongatus in salmon populations from 33 farms in the West of Scotland between 1997 and 2...

Quantitative information was collected through a Delphi survey on the most important clinical signs and risk factors for diagnosis of bovine anaplasmosis, babesiosis, cowdriosis, fasciolosis, parasitic gastroenteritis (PGE), schistosomosis, theileriosis and trypanosomosis, with the aim of compiling ...

During the last 30 years, modelling has increasingly played an important role in improving the efficiency of agricultural production systems. In the case of vector-borne diseases, most of the approaches have focused around calculus methods to describe the dynamics of the interactions of host and...

Readers will be aware that the issue of sea lice infection and control is a problem that affects farms in most salmon-producing areas. However, when discussing the problem or its solution with reference to other countries it is important to understand the major differences as well as similarities in...
