Sea lice, Lepeophtheirus salmonis (Krøyer), are a well-documented parasite of farmed salmonids; infestations can be costly as a result of chemical treatments to salmonids as well as loss of fish due to mortality and morbidity. Some medicinal treatments have been pursued by the salmon industry to control sea lice infestations on farms, but these methods are expensive, stressful to salmon, have detrimental environmental impacts, and can be hazardous to workers. A team from The University of Prince Edward Island, the Centre for Veterinary and Epidemiological Research, and the Atlantic Veterinary College developed an agent-based model to simulate the effects of cleaner fish on sea lice loads of farmed salmonids.
