Mr. Speaker, with respect to the fish, it does seem to me that all animal life cycles are very complicated, but salmon is the most extreme case.
My colleague mentioned the question of temperatures in the river. It seems to me that in a life cycle as complicated as the salmon's, at least one important trigger at various stages of that life cycle must be temperature. He has mentioned the temperature of the rivers, which has been disputed here and I know this is a matter of science. However, he also mentioned the oceans. In climate change at the moment it is becoming increasingly clear that critical changes in temperature in various parts of the oceans are partly triggers and partly a result of climate change. A very significant feature of the current change in climate is changes in the temperature of the oceans.
I wondered, and I know it is science, if the hon. member has any thoughts about the effect of changes in temperature in the ocean part of the cycle of these fish.
