Just to clarify, the data I looked at are the data provided online by the Department of Fisheries and Oceans. The reason I picked data from the last 10 years is that I didn't want to go back too far. There are also challenges in compiling data, which sometimes change at certain times. Since I've only looked at the data from Quebec, I can't confirm that the phenomenon is similar in the rest of Canada, but that is most likely the case. We can't go back more than 10 years because the data aren't necessarily comparable.
