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 ...

Controlling salmon lice on farmed salmon and implications for wild salmon.

CABI Reviews, 2009
Abstract This review documents the extent to which management of salmon lice ( Lepeophtheirus salmonis ) on farms has a measurable impact on the health of wild salmon.

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.

Modelling salmon lice dispersal in Loch Torridon, Scotland

Marine Pollution Bulletin, 2006
A particle transport model is described that is being used to simulate the dispersal of salmon lice (Lepeophtheirus salmonis) larvae in the waters of Loch Torridon. A hydrodynamic model, forced by tides and winds, drives the transport model. Particle movements are strongly influenced by winds, which can lead to formation of lice concentrations in ...

Coho salmon productivity in relation to salmon lice from infected prey and salmon farms

Journal of Applied Ecology, 2010
Summary 1. Pathogen transmission from open net‐pen aquaculture facilities can depress sympatric wild fish populations. However, little is known about the effects of pathogen transmission from farmed fish on species interactions or other ecosystem components.
