Understanding the behavior of Atlantic salmon ( Salmo salar ) in commercial sea cages is critical for developing effective strategies to manage parasites. It is particularly relevant since many preventive measures, such as lice skirts, snorkel cages, and submerged systems, aim to limit encounters between salmon and lice in the upper part of the water column. Furthermore, behavior is also a recognized welfare indicator, with deviations from normal patterns potentially signaling stress or disease.
