“…are external parasites responsible for multi-million dollar losses in the salmon industry worldwide (Costello 2009a), and for some of the major ecological impacts associated with marine aquaculture (Krkošek et al 2007, Costello 2009b, Torrissen et al 2013. Sea lice have a multiple-stage life cycle which includes free-swimming larvae and attached moult stages.…”

“…Their life cycle consists of non-feeding planktonic larvae (nauplii), an infective planktonic copepodite, 1 immature 'chalimus' embedded on the host skin and mobile pre-adults and adults that move freely over the host skin. Sea lice are the most pathogenic parasite in salmon farming and may cost the industry E300 million (US$480 million) a year and 6 per cent of product value (Costello 2009). The planktonic larvae and mobile adults infest farmed fishes from natural populations and adjacent farms, but their progeny are then released from the net pens into the surrounding environment where they may infect wild hosts.…”

How sea lice from salmon farms may cause wild salmonid declines in Europe and North America and be a threat to fishes elsewhere

Fishes farmed in sea pens may become infested by parasites from wild fishes and in turn become point sources for parasites. Sea lice, copepods of the family Caligidae, are the best-studied example of this risk. Sea lice are the most significant parasitic pathogen in salmon farming in Europe and the Americas, are estimated to cost the world industry E300 million a year and may also be pathogenic to wild fishes under natural conditions. Epizootics, characteristically dominated by juvenile (copepodite and chalimus) stages, have repeatedly occurred on juvenile wild salmonids in areas where farms have sea lice infestations, but have not been recorded elsewhere. This paper synthesizes the literature, including modelling studies, to provide an understanding of how one species, the salmon louse, Lepeophtheirus salmonis, can infest wild salmonids from farm sources. Three-dimensional hydrographic models predicted the distribution of the planktonic salmon lice larvae best when they accounted for wind-driven surface currents and larval behaviour. Caligus species can also cause problems on farms and transfer from farms to wild fishes, and this genus is cosmopolitan. Sea lice thus threaten finfish farming worldwide, but with the possible exception of L. salmonis, their host relationships and transmission adaptations are unknown. The increasing evidence that lice from farms can be a significant cause of mortality on nearby wild fish populations provides an additional challenge to controlling lice on the farms and also raises conservation, economic and political issues about how to balance aquaculture and fisheries resource management.

“…The sea lice of the family Caligidae are one of the most major health pathogens for farmed fish. In the Northern Hemisphere the salmon louse Lepeophtheirus salmonis (Krøyer, 1838) alone is responsible for commercial losses in excess of € 180 million in salmonid aquaculture (Costello, 2009).…”
