Norwegian salmon and trout farming company Blom Fiskeoppdrett is alleging that export company Coast Seafood -- a part owner in Blom -- underpaid it over the last six years, resulting in millions in losses.

Maaloy-based Coast, one of the largest seafood exporters in the country, reached an agreement in 2014 with Blom to sell all of the fish the farmer produced. That same year, Coast took an equity stake in the company, which has since grown to a nearly 34 percent share.
