The mackerel that are in the Gulf of St. Lawrence and Atlantic Canada later in the summer migrate to American coastal waters to overwinter. There is a winter fishery in the United States, but the quotas have been greatly reduced, as was mentioned earlier. However, the fishery is still open there, to my knowledge.
So this is a big problem, indeed, which requires concerted action with the U.S. to ensure the return of this stock. If the United States dips into the stockpile when we stop dipping, we won't make it.
