The control of the ectoparasite, sea lice (L. salmonis), on farmed Atlantic salmon in Eastern Canada was complicated by the development of resistance to emamectin benzoate, the primary in-feed medication used since 2000. Field efficacy and bioassay assessments were initiated to address the emergency...

This chapter covers the host range and specificity, morphology, life cycle, physiopathology, parasite-host interactions, role as disease vector and control and prevention (biological control, environmental approach, drug therapy, vaccination and insecticides) of Lepeophtheirus salmonis and Caligus r...

A major challenge for Atlantic salmon farming in the northern hemisphere is infestation by the sea louse parasite Lepeophtheirus salmonis. The most frequent method of controlling these sea louse infestations is through the use of chemical treatments. However, most major salmon farming areas have obs...

Background
Recent focus on earlier detection of pathogen introduction in human and animal populations has led to the development of surveillance systems based on automated monitoring of health data. Real- or near real-time monitoring of pre-diagnostic data requires automated classification of r...

The development and implementation of systems for real-time monitoring of health data has been limited in veterinary medicine by the lack of computerized, automatically collected data. We describe the construction of a surveillance system for early detection of cattle diseases based on laboratory re...

Resistance development to parasiticides has been a problem in both terrestrial and aquatic environments. A major challenge exists in early detection of resistance emergence due to the low frequency at which resistant organisms can occur initially within a population and the difficulty in detecting t...
