Mowi opts not to file an appeal after Hordaland district court dismissed its case in April, but may mount a future legal challenge once Norway's tax settlement decision is confirmed.
The salmon farming company is undertaking a smolt vaccination program in an effort to improve future fish health, after experiencing what CEO Ivan Vindheim calls "a rather challenging quarter".
Mowi is the second salmon farmer to undergo auditing by the Norwegian Food Safety Authority Mattilsynet, which has identified four areas where it says the company has deviated from regulations.
