Salmon market analysts say they are unwilling to try to guess how Mowi's lawsuit against the Norwegian government's production tax will pan out but understand the company's reasoning for taking legal action.

It's almost a year since Norwegian government first proposed the introduction of a 40 percent resource tax on salmon and trout farming companies, touching off controversy in the sector and pushback from the country's salmon farming firms.

The Norwegian government justified the proposed tax hike, saying the companies use fjords and sea areas belonging to the community with licenses issued by the state, and is given an unlimited protected right to operate as an industry.
