Snorkel technology to reduce sea lice infestations: efficacy depends on salinity at the farm site, but snorkels have minimal effects on salmon production and welfare

Sea lice are a critical health issue in most salmonid farming regions. New cage-based technologies can prevent infestations from occurring, such as the ‘snorkel’, which introduces an impermeable

Sea lice removal by cleaner fish in salmon aquaculture: a review of the evidence base

There is a mismatch between the current evidence and the extent of use by the industry, and more targeted, evidence-based use of cleaner fish should increase their efficacy and help to alleviate economic, environmental, and ethical concerns.

Sea lice prevention strategies affect cleaner fish delousing efficacy in commercial Atlantic salmon sea cages

It is demonstrated that different in-cage anti-lice strategies altered the magnitude of lice consumption in corkwing wrasse at this site and for this production period.

Planktonic and Parasitic Sea Lice Abundance on Three Commercial Salmon Farms in Norway Throughout a Production Cycle

The present article reports the densities of planktonic sea lice (Lepeophtheirus salmonis and Caligus elongatus) in three Atlantic salmon (Salmo salar) localities, and the relationship between the



Sea lice infestation levels decrease with deeper 'snorkel' barriers in Atlantic salmon sea-cages.

Deeper snorkel depths dramatically and consistently reduced infection levels of salmon lice compared with shallow snorkels, without consequences for fish welfare and production performance.

Salmon lice – impact on wild salmonids and salmon aquaculture

The use of cleaner fish has emerged as a robust method for controlling salmon lice, and aquaculture production of wrasse is important towards this aim.

The Cost of Lice: Quantifying the Impacts of Parasitic Sea Lice on Farmed Salmon

This empirically investigate the biological and economic impacts of observed levels of infective lice in Norwegian salmon farms over an 84-month period, estimating that lice parasitism produced US$436m in damages to the Norwegian industry in 2011.

Recent failure to control sea louse outbreaks on salmon in the Broughton Archipelago, British Columbia

It is proposed that a combination of poorly timed treatments and warm environmental conditions likely explains the outbreak of native ectoparasitic copepods in the salmon-farming region of the Broughton Archipelago, British Columbia.
