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...

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...

Purpose

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...

This paper discusses a comparison of one heuristic and two Bayesian belief network based expert systems used to aid veterinarians in the process of differential diagnoses of equine diseases where coughing is the presenting clinical sign. Each implementation infers the likelihood of the presence of a...

The long and narrow Hardanger fjord in western Norway has a high density of salmon farms and has had severe salmon lice, Lepeophtheirus salmonis, problems. In the years 2004-06, salmon lice numbers were recorded in selected salmon farms in the fjord as part of a larger research project. Most farm si...

Provides a review of the literature related to the application of domain-specific thesauri in the search and retrieval process. Focusing on studies that adopt a user-centered approach, surveys the methodologies and results from empirical studies undertaken in the use of thesauri as sources of term s...
