Effects of temporal, geographical and environmental factors on salmon lice (Lepeophtheirus salmonis) levels of Atlantic salmon (Salmo salar) in Ireland.

ABSTRACT: The salmon louse (Lepeophtheirus salmonis) poses a major challenge for Atlantic salmon (Salmo salar) aquaculture in the northern hemisphere. These ectoparasites feed on the blood, tissue, and mucus of their fish host, causing skin damage, increasing susceptibility to secondary infections, and, in severe cases, leading to fish mortality. The economic impact on aquaculture is substantial due to treatment and management costs. Effective management strategies rely on a comprehensive understanding of infection dynamics. To investigate these dynamics, we analysed a 30-year dataset on sea lice abundance from Atlantic salmon farms in Ireland, collected by the Marine Institute through the National Sea Lice Monitoring Programme. Using generalised linear mixed-effects models, we detected temporal flu
