Organophosphate Poisoning of Atlantic Salmon in Connection with Treatment against Salmon Lice [PDF]
Acta Veterinaria Scandinavica, 1989 Three incidents with high mortality in Atlantic salmon after trichlorfon treatment against salmon lice are described. All 3 incidents occurred at water temperatures of 12 degrees C or higher. The mean brain acetylcholinesterase (AChE) activity of dead fish was less than 20% of normal activity, while survivors showed mean activities of 22-61% of normal ...

Aquaculture Environment Interactions, 2021 Salmon lice Lepeophtheirus salmonis pose a major threat to the sustainable development of salmonid farming. To investigate effects of farm-origin salmon lice on wild salmonids, salmon lice dynamics are typically simulated using models that depend on ...

The effectiveness of hyposaline treatments against host-attached salmon lice. [PDF]
Sci Rep, 2019 AbstractUnderstanding how salinity affects marine parasites is vital to understanding their ecology and treatment, particularly for host-parasite systems that traverse marine and freshwater realms such as the globally important Atlantic salmon (Salmo salar), salmon louse (Lepeophtheirus salmonis) system.

Aquaculture Environment Interactions, 2017 Atlantic salmon Salmo salar has shown declines in abundance associated with reduced survival during marine life stages. Key impacts on survival may include a changing ocean environment and salmon louse Lepeophtheirus salmonis infestation from aquaculture.

Prediction of the salmon lice infestation pressure in a Norwegian fjord [PDF]
ICES Journal of Marine Science, 2020 AbstractA further growth in the Norwegian aquaculture industry might potentially be hampered by the conclusion that it is not environmentally sustainable. As direct measurements of the lice induced mortality on wild salmonids are impossible, the management is based on a set of high-quality and well-documented sustainability indicators. These indicators

PLoS ONE, 2011 BackgroundPathogens are growing threats to wildlife. The rapid growth of marine salmon farms over the past two decades has increased host abundance for pathogenic sea lice in coastal waters, and wild juvenile salmon swimming past farms are frequently ...

Lice pressure from salmon farms on wild sea trout (Salmo trutta) in a Norwegian fjord
Frontiers in Marine Science, 2015 Salmon lice Lepeophtheirus salmonis are external parasites on salmonids in the marine environment. However, during recent years, salmon lice abundance has increased due to the presence of salmon farming.

Salmon lice treatments and salmon mortality in Norwegian aquaculture: a review [PDF]
Reviews in Aquaculture, 2018 AbstractWith the expansion of Atlantic salmon aquaculture, the economic and ecological impacts of salmon lice (Lepeophtheirus salmonis) has increased. Norway battles this problematic parasite with various control and preventative methods within farms. We analysed two national‐level databases to examine the number of operations reported each year from ...

Epidemics, 2014 Infection by parasitic sea lice is a substantial problem in industrial scale salmon farming. To control the problem, Norwegian salmonid farms are not permitted to exceed a threshold level of infection on their fish, and farms are required to monitor and ...
