“In summer 2017, after a sea lice infestation (>3 lice/fish), the pen under investigation was treated using Salmosan®Vet (azamethiphos, 500 mg/g powder) bath for three consecutive treatments, with 12 days between first and second treatment and 21 days between the second and third treatment. An enclosed plastic skirt (1800 m3) was used, and fish were treated with 0.2 ppm of azamethiphos for 45 min with additional oxygen injection as suggested by the manufacturer”.

should read:

“In summer 2017, after a sea lice infestation (>3 lice/fish), the pen under investigation was treated using chemical bath sea lice treatment containing the active ingredient azamethiphos for three consecutive treatments, with 12 days between first and second treatment and 21 days between the second and third treatment. A tarpaulin (1800 m3) was used, and fish were treated with 0.1 ppm of azamethiphos for 45 min with additional oxygen injection as suggested by the manufacturer”.

In the Results section under subheading ‘Seawater conditions and fish general health’,

“There were no immediate mortalities after the first two azamethiphos exposures, whereas mortalities occurred at the rate of 1% after the third exposure”.

should read:

“There were no immediate mortalities after the first two azamethiphos exposures, whereas mortalities occurred at the rate of 0.4% after the third exposure”.
