Stress response of Salmo salar ( Linnaeus 1758) facing low abundance infestation of Caligus rogercresseyi ( Boxshall & Bravo 2000), an object in the tank, and handling
Abstract This study looks at how low infestation loads of adult Caligus rogercresseyi and other stressors affect the physiology of Salmo salar . Experimental fish groups were with (infested) or without (control) exposure to the parasite. The parasite cohort was followed for 78 days post‐infestation...
