Investment in alternative aquaculture feed ingredients may start to slow as an indirect consequence of the proposed new resource tax announced by the Norwegian government last week, industry executives warned.

Government officials proposed a new resource tax on salmon and trout farming of 40 percent for larger companies. The proposed tax, which must still be approved by the Norwegian Parliament, is set to take effect on Jan. 1, 2023 and will apply to volumes above 4,000 or 5,000 metric tons.
