Optimal salmon lice treatment threshold and tragedy of the commons in salmon farm networks [PDF]

Aquaculture, 2019
Abstract The ectoparasite Lepeophtheirus salmonis has for decades plagued salmon aquaculture by decreasing profits and impacting wild salmon stocks. To protect migrating wild salmon stocks and avoid excessive cross-farm infections, authorities require treatments when sea lice level reach a given threshold.

Effects of salmon lice infection and salmon lice protection on fjord migrating Atlantic salmon and brown trout post-smolts

Hydrobiologia, 2007
Effects of artificial salmon lice infection and pharmaceutical salmon lice prophylaxis on survival and rate of progression of Atlantic salmon (n = 72) and brown trout post-smolts (n = 72) during their fjord migration, were studied by telemetry. The infected groups were artificially exposed to infective salmon lice larvae in the laboratory immediately ...

Atlantic salmon infected with salmon lice are more susceptible to new lice infections

Journal of Fish Diseases, 2016
AbstractAggregation is commonly observed for macroparasites, but its adaptive value remains unclear. Heavy infestations intensities may lead to a decrease in some fitness‐related traits of parasites (e.g. parasite fecundity or survival). However, to a dioecious parasite, increased aggregation could also increase the chance of finding individuals of the

The physiological effects of salmon lice infection on post-smolt of Atlantic salmon

Journal of Fish Biology, 1996
The physiological effects of salmon lice infections on post‐smolt of Atlantic salmon were examined by experimentally infecting hatchery reared post‐smolts with infective copepodids. Even at high infection intensities, ranging from 30–250 lice per fish, early chalimus stages did not have severe, physiological effects on the fish.

Salmon lice from aquaculture reduce marine survival of Atlantic salmon

Journal of Animal Ecology
Abstract Salmon lice from marine salmon aquaculture have been shown to impact the survival of wild salmon migrating through aquaculture areas, but quantifying the level of impact has proven difficult. This difficulty has led to the use of randomised control trials.
