Which of the following is no longer allowed in the atlantic provinces?

Cod fishing is no longer allowed in the Atlantic Provinces, if your other options are fishing, aquaculture, and fish processing. Due to the fact that the population of cod has drastically decreased, it is now forbidden to fish cod in these areas. Other fish can still be fished, but not cod. Also, aquaculture refers to various species of fish and plants in the waters, so that cannot be forbidden. And there is no reason to forbid fish processing, it just means to clean the fish so that it can be sold to people and eaten.
