The influence of aquaculture unit proximity on the pattern of Lepeophtheirus salmonis infection of anadromous Salmo trutta populations on the isle of Skye, Scotland

Abstract: A total of 230 anadromous Salmo trutta (brown trout) were sampled in five sheltered coastal fjords (or sea lochs) on the Isle of Skye, Scotland, U.K., in 2016 at varying distances from active Atlantic salmon Salmo salar farms. Statistical models were developed to investigate potential correlations between salmon lice Lepeophtheirus salmonis burdens on S. trutta hosts and their proximity to S. salar farm cages. Significant correlations were found between lice burdens and fish fork length and proximity to the ne… Show more

“…Sea lice induce ionoregulatory dysfunction, physiological stress, anaemia, reduced feeding and growth, changes in post-smolt behaviour, increased susceptibility to secondary infections, reduced disease resistance and ultimately mortality of individual sea trout (Finstad & Bjørn, 2011;ICES, 1997;Poole, Nolan, & Tully, 2000). On the other hand, in farm-intensive areas, sea lice levels on wild sea trout are typically higher (Gargan et al, 2003;Moore et al, 2018;. On the other hand, in farm-intensive areas, sea lice levels on wild sea trout are typically higher (Gargan et al, 2003;Moore et al, 2018;.…”

“…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).
