“…Sea lice infestations in these areas regularly exceed more than 0.35 lice per gram of fish mass, initiating physiological disturbance to the trout with weight range from 16 to 70 g (Wells et al, 2006(Wells et al, , 2007. The sea lice levels on wild sea trout are particularly high within 30 km of salmon farms, but elevated lice infestations extend beyond this distance (Gargan et al, 2003;Moore et al, 2018;Serra-Llinares, Bjørn, Finstad, Nilsen, & Asplin, 2016;Serra-Llinares et al, 2014;Tully, Gargan, Poole, & Whelan, 1999).
