Yes.
Over those years, researchers at the Department of Fisheries and Oceans, oceanographers, have shown that in the Labrador Sea in particular, that is to say in the salmon--and cod--wintering zones, water temperatures have been abnormally cold during several consecutive years. This had a very important effect on the survival of the fish that were there during the winter. Since then, the water temperature has returned to normal.
If you look at temperature graphs for all of Canada, you will see that the Labrador Sea currents are often colder than water in other regions. Climatologists attribute this to the more rapid melting of glaciers in the North, which makes the water colder and sends more cold water into the Labrador Sea.
However, that is not the only factor. There have been other changes at sea. People will talk to you about the increase in the number of predators such as seals. The populations of gulf seals have gone from approximately a million to six, seven, eight or ten million. Of course, seals eat almost no salmon. It is very rare. But if each seal ate one salmon in a given year, there would not be any left. In fact, the quantity of salmon predated by seals is very low.
These ocean changes have not only affected salmon and cod, but there has also been the appearance and disappearance of certain species of plankton. We have observed enormous changes. It is logical to conclude that global climate change has had an effect on the ocean and on the species that live in it. I hear more and more researchers talking about this. Yesterday, researchers presented a report on birds that are in difficulty in North America. This is particularly the case for marine birds. I think that birds and fish are affected by climate change that affects the ocean.
